Ingredients:
1 cup of melted unsalted butter
1 1/2 cups of granulated sugar
1/2 cup of packed brown sugar
4 large eggs
1 teaspoon of vanilla extract
1 cup of all-purpose flour
3/4 cup of unsweetened cocoa powder
1/2 teaspoon of salt
1/2 teaspoon of baking powder
1 cup of semi-sweet chocolate chips
1/2 cup of chopped walnuts (optional)
Instructions:
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish or line it with parchment paper.
In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until the mixture is smooth.
Add the eggs one by one, beating well after each addition, and then mix in the vanilla extract.
In a separate bowl, sift together the flour, cocoa powder, salt, and baking powder. Gradually incorporate the dry ingredients into the wet mixture, stirring until just combined.
Gently fold in the chocolate chips and walnuts, if using.
Pour the batter into the prepared baking dish and spread it out evenly.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Allow the bars to cool completely in the dish before slicing into squares.
