Heat oven to 375°F. Line 2 cookie sheets with parchment paper.
Cream butter and sugar until light, about 3 to 4 minutes. Add vanilla extract and eggs and mix well.
2/3 cup (150g) salted butter, 1 1/2 cups (300g) brown sugar, 2 teaspoons vanilla extract, 2 large eggs
Combine the flour, cocoa, salt and soda and whisk, then add to the butter, sugar and eggs and stir to combine. Stir in chocolate chips and walnuts.
1 1/2 cups (212g) all-purpose flour, 1/3 cup (35g) unsweetened cocoa powder, 1/2 teaspoon salt, 1/2 teaspoon baking soda, 1 cup semisweet chocolate chips, 1/2 cup coarsely chopped walnuts
Drop onto the parchment-lined cookie sheets using a scoop for evenly sized cookies. Freeze the cookie dough balls for 20 minutes or chill in the fridge for 1 hour.
Bake for 9-11 minutes until mostly set in the center, but be careful not to overbake. The cookies will set up more as they cool.
Let the cookies cool on the pan for a few minutes before transferring to a wire rack to cool completely. Dust with powdered sugar and enjoy.
Powdered sugar

Chilling the dough isn't required but it does help them bake up slightly thicker and spread a bit less.
