These double chocolate chip walnut cookies are incredibly delicious and easy! We love them with walnuts, but hazelnuts or almonds would also be delicious. We use a handheld mixer, but a stand mixer works, too. I use salted butter in the recipe, but you can use unsalted butter (add ¼ teaspoon of salt to the batter to accommodate).
1 cup all-purpose flour, spooned and leveled (130g)
¼ cup unsweetened cocoa powder (20g)
½ teaspoon baking soda
8 tablespoons salted butter, at room temperature (113g)
½ cup granulated sugar (100g)
½ cup brown sugar (100g)
1 teaspoon vanilla extract
1 large egg, at room temperature
¾ cup chopped walnuts (85g)
½ cup chocolate chips (85g)
1Prep: Preheat the oven to 350°F (177°C). Line two baking sheets with parchment paper or use a silicon baking mat.
2Mix dry ingredients: Sift or whisk the flour, cocoa powder, and baking soda together. Set aside.
3Cream butter and sugar: Add the butter, sugars, and vanilla to a large bowl. Cream the butter and sugars together until light and fluffy, 3 to 5 minutes. You can also use a stand mixer fitted with the paddle attachment.
4Add egg: Scrape the side and bottom of the bowl, and then add the egg. Mix on medium-low speed for 30 seconds. The egg will not be completely incorporated.
5Make cookie dough: Turn the speed to the lowest setting. Add the dry ingredients in three parts, mixing until just combined, 1 to 2 minutes. With the mixer on low, add the walnuts and chocolate chips and mix until just incorporated.
6Bake: Drop heaped tablespoons of cookie dough onto baking sheets (or use a medium cookie scoop). Leave 2 inches between the cookies to allow for spreading. Lightly press cookie dough mounds down towards the baking sheet.
7Bake the cookies, one sheet at a time, for 8 to 10 minutes. The edges should be dry, and the tops should be slightly cracked. Let the cookies cool on the baking sheet for 2 minutes, then transfer them to a wire rack to cool completely.
