This is the best blondie recipe I’ve made. They are perfectly chewy and fudgy, and I love that the batter comes together in just one bowl.
Imagine a brownie, but instead of rich chocolate or cocoa, it has a warm, caramel-like vanilla flavor. That’s a blondie! The key to that classic flavor is using melted butter and brown sugar as the base of the batter.
This blondie recipe is incredible when made with plain melted butter, but for even more flavor, you have the option to make brown butter blondies. Browning the butter first adds a nutty and toasty flavor that really takes them to the next level. This simple step only takes an extra 5 minutes, but makes a big difference in the end.
Key Ingredients
- Butter: The secret to rich and flavorful blondies. I use unsalted butter, and for an extra toasty flavor, I love to brown the butter, as shown in our recipe video below. See how to brown butter for more tips.
- Brown Sugar: The toasty notes of the molasses in brown sugar make these taste like sweet caramel. Light brown sugar is fine, but if you have it on hand, I love using dark brown sugar for even more flavor.
- Egg: The egg provides structure and helps make them fudgy in the middle. A room temperature egg mixes better into the batter, so either leave it out on the counter for a bit, or quickly warm up your egg by placing it in a bowl of lukewarm water for 5 minutes before adding it to the batter.
- Vanilla and Salt: Just like when making homemade chocolate chip cookies, vanilla and salt help the bars taste amazing. If you have almond extract on hand, add a little dash (it’s delicious).
- Flour: I use all-purpose flour, which provides some structure, although I don’t use much of it. Like when making our favorite homemade brownies, we only add a little flour to the batter (more flour results in a cakey, drier texture).
- Chocolate Chips: I love chocolate chip blondies, but I’ve provided tips for using other mix-ins in our recipe. Consider white chocolate chips, butterscotch chips, peanut butter chips, chopped candy bars, M&Ms, dried fruit, or nuts. Anything goes!

How to Make the Best Blondies
Tip 1: Melt the butter. Starting with melted butter makes these blondies so easy to mix. You don’t need a mixer or softened butter. Whenever I can use melted butter in baking, I do (see our chocolate chip cookies as proof). Since we’re melting it anyway, take the extra minute to make brown butter for a toasty, caramelized flavor.
To brown the butter, swirl it in a saucepan over medium-low heat. It will melt, get foamy, and then turn golden brown with a nutty aroma.
Tip 2: Combine the butter and sugar. Whisk the still-warm butter into the brown sugar (we use all brown sugar for a rich, caramel-like flavor). The mixture may look a bit greasy or gritty at first, but don’t worry. It’s normal, and it will smooth out once the other ingredients are added.
Tip 3: Add the egg and flavorings. When the butter-sugar mixture is no longer hot to the touch, whisk in the egg, vanilla, salt, and optional almond extract. The liquid from the egg helps smooth the batter and brings everything together, just as it does when making our one-bowl brownies.
Tip 4: Add a small amount of flour. There’s very little flour in this blondie recipe, and that’s on purpose. Using less flour keeps them dense and fudgy rather than cakey. You’ll also notice there’s no baking powder or baking soda. That’s how we keep the texture chewy. (If you prefer a bit more lift, check the recipe notes for an easy adjustment.)
Tip 5: Fold in mix-ins. Here’s where you can have some fun. This batter can handle about 1 ½ cups of mix-ins. We used chocolate chips in our video and photos, but you can switch it up with crushed freeze-dried strawberries and white chocolate chips, chopped candy, nuts and dried fruit, or sprinkles for a funfetti-style twist.
Tip 6: How to know when blondies are done. The biggest mistake you can make is baking your blondies for too long. For the best texture, remove them from the oven when the edges are set but the center looks shiny and slightly underbaked. Just like when baking our fudgy brownies, these will continue to set and firm up in the middle as they cool.
Serving Suggestions
These blondies are incredible all on their own, but I wouldn’t be doing my job if I didn’t share a few of my favorite ways to serve them. They’re wonderful warm with a scoop of vanilla ice cream, or chilled (almost frozen) and crumbled over the top of ice cream for a little crunch.
You can even turn them into a blondie sundae, and drizzle them with chocolate or caramel sauce, add whipped cream, and finish with a cherry on top. Yum!

This blondie recipe makes dense, rich, and fudgy blondies with a paper-thin, crinkly top. If you have it, use dark brown sugar. In our video, we use browned butter (adding an extra 5 minutes to the prep time). You can use plain melted butter in this recipe, but brown butter adds a lovely, toasty caramel flavor.
I love how fudgy and gooey these turn out. With our recipe, the bars will be around ½ inch thick. We love them this way, but for thicker blondies, try adding baking powder to your batter (see tips below the recipe).
Watch Us Make the Recipe
You Will Need
8 tablespoons unsalted butter (113g)
1 cup dark or light brown sugar, lightly packed (200g)
1 large egg at room temperature
1 teaspoon vanilla extract
¼ teaspoon almond extract, optional
¼ rounded teaspoon fine sea salt, decrease a little if sensitive to salt
1 cup all-purpose flour, spooned and leveled (130g)
1 cup chocolate chips (170g)
½ cup optional extras like toasted nuts or dried fruit (85g)
Directions
1Prep the oven and pan: Preheat the oven to 350°F (180°C). Lightly butter and line an 8×8-inch baking pan with aluminum foil or parchment paper.
2Prep the butter: Melt the butter or make browned butter. To make browned butter, add the butter to a heavy-bottomed pan over medium-low heat. As the butter melts, continuously swirl it around the pan. It will melt, get a little foamy, and finally turn golden brown. Remove it from the heat when the butter is light brown and smells nutty.
3Make the batter: Whisk the warm butter into the brown sugar until blended. The mixture will look greasy and gritty. Set aside for a few minutes to cool. When the sugar and butter mixture is warm, not hot, add the egg, vanilla, almond extract (optional), and salt. Stir until smooth and ever so slightly lighter in color.
4Add the flour: Add the flour in two additions, gently folding it into the batter after each addition until you no longer see streaks of flour.
5Add the mix-ins: Stir in the chocolate chips and any additional add-ins like nuts or dried fruit.
6Bake blondies: Spread the batter evenly in the prepared pan. It just covers the bottom of the pan. The batter is very thick, so gently pressing the batter into the corners helps. Bake until the edges look dry and the middle looks shiny and slightly underbaked, 20 to 30 minutes.
7Cool and cut: Cool to room temperature before removing from the pan, allowing them to set in the middle. Cut into 16 squares. Don’t be surprised if the blondies have not risen much (they should be about ½-inch thick). These are supposed to be dense, rich, and a little fudgy.
Adam and Joanne's Tips
- Storing: Keep these in an airtight container at room temperature for 2 to 3 days. Or store them in the fridge for 2 weeks. You can also freeze them for up to 3 months! I like wrapping them individually so I can take one or two out of the freezer.
- Baking powder: For taller 1-inch blondies, whisk ½ teaspoon of baking powder with the flour before adding to the batter. They will be a bit less fudgy.
- Measuring flour: Weigh it or use the “spoon and level” method. Fluff the flour, spoon it into the measuring cup, then level off the top with a flat edge.
- Baking tips: We consistently achieve excellent results when baking these in a 350°F oven for 23 minutes. Ovens vary, and bake time can be affected by the pan you use. We remove the pan when the top looks shiny and light golden brown. The batter might still look slightly wet if there are cracks, but the middle should not wiggle like jello.
- Baking pan: We recommend using an 8-inch metal square pan (ours is from USA Pans), as it provides consistent heat distribution and baking results. Glass and ceramic pans are okay. Due to their different heat transfer properties, they may require a longer baking time.
- Doubling the recipe: Double all the ingredients and bake in a 9-inch by 13-inch baking pan. They will be slightly thicker. The bake time will be similar, but keep an eye on them and use our visual cues in the recipe as a guide.

I made these with gluten free flour, and they were incredible! So good!
Hi- about to make these but realized I only have a 9×9 inch square baking pan. How can I adpat recipe? Thank you!
Hi Rachel, You should be fine, they will just be slightly thinner.
I’m from France and couldn’t find a good blondies recipe on my usual French blogs, so I tried this one. I made the brown butter version and it was absolutely fantastic! The flavor was amazing. I will definitely double the quantities next time 🙂
You’re right! I also tried the brown butter version and I will always do so in the future! The blondies had the most delicious caramel flavor.
Yay! 🙂
Wow! These are perfection, and SO easy to make! So much better than making chocolate chip cookies! Perfect, every time!! I’ve made these several different times, in several different ways: white chips, butterscotch chips, toffee bits, etc., but really enjoy them with 1 1/2 cups semisweet chips. Thank you so much!!
You are so welcome! 🙂
I’ve made this recipe twice: the first time with plain melted unsalted butter, and the second time with browned butter. Well, I will always make these blondies with browned butter in the future! The caramel-like flavor is incredible, especially when using dark brown sugar. I added vanilla chips and toffee brickle. Rave reviews! Thank you for this wonderful recipe.
You are so welcome and so we glad you love the recipe! Thank you for coming back to leave a review 🙂
I followed this recipe exactly, added chocolate chips…it was INCREDIBLE! The best easy treat I’ve ever made. Need to make it a weekly staple – so decadent with a perfect texture. Easy for a beginner baker.
Hi! So I have a question regarding the amount of sugar. In the recipe it calls for 115 grams but that adds up to about 3/4 of a cup when lightly packed. Is there a chance theres been an error? Thank you 🙂
Oh no! You are absolutely correct. The grams provided were incorrect. I’ve corrected it. you will need 1 cup or 200 grams of brown sugar in this recipe.
The original recipe here was STELLAR! This is NOT the original recipe on the blog. Your ratio to of brown sugar and flour are not the same. I made this over a second time because I thought I mucked up the first batch. The original recipe has a shiney crinkly top. This recipe doesn’t have enough sugar and too much flour. I am a professional baker for a living, I’m no novice. I loved this recipe so much I had it saved from years ago as my go to when I made blondies. I just thought it would be easier if I pulled it up on my phone to get the recipe. Turns out I had to dig in my files to determine what happened as there was no way I made the same mistake twice. Please adjust to the original gram weight you had previously. Thank you.
Hi Carrie, You are so right! When editing this recipe, we mistakenly changed the gram weight. Very sorry and it is fixed now.
Could you add in diced apples to make it more of an apple blondie?
That sounds great!
I’ve been in love with this recipe for years. It’s my go-to whenever I want to bring dessert to work or to friends. And EVERYTIME, I’m asked for the recipe. It’s a killer!!! Recently I’ve found that melting about 25% of the chips in the batter gives it a more chocolatey flavour which is also delicious. Thank you for this wonderful recipe
Have made this several times. This is the first time I ever doubled it. Directions were spot on. Taking it to a cookout tomorrow. Thank you! Judging from that extra batter, which I already sampled, I have a hit!
10/10! This recipie is so bomb. The blondies wre crispy and sweet. Perefect chocolate ratio.
Absolutely delicious! I know my family will ask me to make these blondies again and again. I did use the 1/2 teaspoon of baking soda to make them a little more cookie-like. Thanks for all your great recipes!
This recipe has long been a favorite of mine. I’ve been asked to make it many, many times. I use white chocolate chips as the add-in and have on many occasions made a boozy version with bourbon. The bourbon with the brown sugar is definitely a good combo! A colleague of mine used butterscotch chips as the add-in. I’m gonna have to try that next time! They turn out perfect every single time!
I’m sorry to hear that your blondies turned out flat and oily! We understand that sometimes recipes can be a bit finicky, and results can vary. Our blondie recipe is designed to be on the denser, chewier side, which is why it doesn’t include a leavening agent like baking soda or powder. Many of our readers, and we ourselves, love them for their rich, fudgy texture without the lift a leavener provides. While we’re confident in the recipe as written, baking can sometimes be a bit of an experiment. For a lighter, cake-like blondie, you could try adding 1/2 teaspoon of baking powder to the dry ingredients next time!
Would the recipe work if I make mini cupcakes?
Yes, I have done this many times. You may have a shorter baking time, though.
I’m glad I tried these out, they’re better than a previous blondie recipe I have used. The browned butter flavor is great. Next time I will skip the almond extract, it tastes like maraschino cherries to me.
Wonderful! So glad you enjoyed them 🙂
These are the GOAT!!!!
The recipe is perfect as is. I seriously can eat a whole pan alone. I was feeling a little adventurous one day and added a teaspoon of creamy PB mixing in well right before adding the egg, then topped with mini chocolate chips right before they went into the oven. If you do not have a nut allergy, may i suggest trying this as it is AMAZING. Otherwise they are still AMAZING just the way they are and for that i sincerely thank you for this recipe!
Love this so much! So happy you love them!
these are great – buttery and sweet. My pickleball group absolutely loves them!
these look delicious 🙂 and I’ve looked up tons of blondie recipes just now haha I usually make brownies with almond flour.. I think I could just sub it in here. What do you think?
I love how simple this recipe is! I used 1/2 cup each of light brown sugar and muscovado sugar. I did opt for the 1/2 tsp of baking power because to me a taller bar feels like a bigger portion 🤭. I used 1/2 cup each of white and milk chocolate chips, and 2/3 cup of macadamia nuts. The only hard part is spreading the dough, as it is very sturdy. Take the time to gently work the dough into all corners with a small spatula. I will make these again and again – they are a great alternative to cookies.
These are so delicious. I took mine out at 20 minutes to keep them very moist, and retain more flavour! 10/10!
Hi, I was wondering if I could use just an egg yolk, or two egg yolks, or an egg yolk with some buttermilk/whole milk and vinegar mix instead if a whole egg? I’ll be using egg whites and have leftovers. Would it affect the rise? I want them on the thicker side. Thanks for any help you can give
Hi May, Changing the eggs in this recipe will create different results. You may still enjoy them, I just cannot say how they will turn out since I have not tried the changes myself.
my favorite blondie recipe. Quick, easy and so good.
Your recipes are fantastic!!! You helped me perfect my brownies, and now, I’ve been able to do the same with these blondies! I chopped up some Ritter Sport chocolate and topped it before putting it into the oven. I love the depth of flavour that browning the butter adds. What a treat! Thank you for your clear, concise and absolutely delicious recipes.
These were delicious and didn’t last long at all, everyone loved them. Toasting the butter was easy and added so much flavour.
These were so good! I had some left over butterscotch chips so I added those instead of chocolate and they were perfect. The whole family loved them!
Heyy I don’t have any doubt about the taste but if I’m using a tray 11 inch by 11 inch tray how much time would you recommend ? Thank youuuu !
Hi Zoyaaa, I think your pan will be too large for this recipe. You may want to double the recipe. I’d keep an eye on them while they bake and expect them to take 5 to 10 minutes longer.
I have not made yet but they look thin compared to my current recipe… Could I double the quantity but still use the same size tin? Also I’d love a metric version please!!
Yes, you can double it. Just expect them to take longer in the oven.
Oh no! So sorry to hear your blondies hardened after cooling. They should definitely stay soft and chewy. I’m wondering if they might have been overbaked slightly, or perhaps stored uncovered? Blondies can dry out if left exposed to air.
Have made this a few times. Turns out perfect every time. Few ingredients, easy instructions, super results. This one is a keeper.
I just loved this recipe. I make your brownie recipe for several years, so I knew already that this one should be great. And it is! I used the brown butter (it was my first time making it and it turn out perfect). The flavor is very rich. I bake it for 23 minutes but I guess I wil try 20 minutes the next time. Thank you for the recipe!
Very easy to make. I baked them for 20 minutes, but think I’ll go an additional 5 next time. Very good, but very sweet.
This was the best blondie recipe I’ve ever made! I took a page from your brownie recipe and mixed everything in the pot on the stove and it turned out beautifully. It turns out that 23 minutes ended up being perfect our my oven as well. I was shocked at how quick and easy it was to make (even with my 3 year old helping.) I’m absolutely making these again and can’t wait to try out more from your blog!
My son is egg free, so I subbed the egg with canned coconut milk. Turned out excellent! My husband told me to keep the recipe 😉
Perfect indeed! I had made your brownie recipe several times. So I had to try the blondies. The texture was just right – – soft and gooey on the inside with nice crisp outer edges. The melted brown butter added an irresistible carmelization. And of course the chocolate chips made them all the more decadent. Total win all around!
