In a bowl, whisk the eggs with the granulated and brown sugar until frothy, about a minute. Add the melted butter and vanilla extract and whisk until incorporated.

In a separate bowl, whisk the flour, cacao powder (sift it if it’s clumpy), baking soda, baking powder, salt, and espresso powder.
195 grams whole wheat flour, 20 grams cacao powder, 1 teaspoon baking soda, 1/2 teaspoon baking powder, 1/2 teaspoon salt, 1 teaspoon espresso powder or instant coffee
Add the dry ingredients to the wet and mix them in using a silicone spatula.
Fold in the chopped chocolate or chocolate chips.
200 grams chopped chocolate or chocolate chips
Cover the bowl with plastic wrap or a shower cap and refrigerate for 1 hour.
Preheat the oven to 350F (180C).
Using a 2-inch-diameter cookie scooper (5cm), scoop each cookie into a parchment-paper-lined baking tray. Leave about 2 inches of space between each one.
Bake on the middle rack for 10 minutes. Remove from the oven. Let them rest on the baking tray for 2-3 minutes. Transfer the cookies to a cooling rack to cool completely. Enjoy!
