# What You'll Need:
→ Dry Ingredients
01 - 1 cup all-purpose flour
02 - 1/2 cup unsweetened cocoa powder
03 - 1/2 teaspoon salt
04 - 1/2 teaspoon baking powder
→ Wet Ingredients
05 - 1 cup unsalted butter
06 - 2 cups granulated sugar
07 - 4 large eggs
08 - 2 teaspoons vanilla extract
→ Add-ins
09 - 1 cup chopped walnuts
10 - 1/2 cup semisweet chocolate chips (optional)
# How to Make It:
01 - Preheat the oven to 350°F. Grease a 9x13-inch baking pan or line it with parchment paper.
02 - Place the butter in the baking pan and melt it in the preheating oven. Remove the pan and stir in the granulated sugar until fully incorporated.
03 - Add the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract until uniform.
04 - Sift the flour, cocoa powder, salt, and baking powder over the wet mixture in the pan. Fold gently with a spatula until just combined.
05 - Incorporate the chopped walnuts and optional chocolate chips evenly into the batter.
06 - Smooth the batter evenly in the prepared pan. Bake for 28 to 32 minutes, or until a toothpick inserted in the center yields a few moist crumbs.
07 - Allow the brownies to cool completely in the pan before cutting into twelve squares.
