Detailed Directions and Instructions
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or line it with parchment paper for easier removal.
Step 2: Combine the Dry Ingredients
In a medium bowl, sift together 1 cup of all-purpose flour, 1 cup of granulated sugar, 1/3 cup of unsweetened cocoa powder, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. Set this mixture aside.
Step 3: Melt the Butter and Chocolate
In a saucepan over low heat, melt 1/2 cup of unsalted butter and 1 cup of semi-sweet chocolate chips, stirring until smooth. Remove from heat and let it cool slightly.
Step 4: Mix Wet Ingredients
In a large mixing bowl, whisk together 3 large eggs, 1 teaspoon of vanilla extract, and the melted chocolate mixture until well combined.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet mixture, stirring until just combined. Do not overmix to ensure a fudgy texture.
Step 6: Bake the Brownie Cake
Pour the batter into the prepared baking pan and smooth out the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but not wet batter.
Step 7: Cool Completely
Once baked, remove the pan from the oven and let the brownie cake cool in the pan on a wire rack for at least 30 minutes.
Step 8: Prepare the Peanut Butter Frosting
In a medium bowl, beat together 1/2 cup of unsalted butter, 1 cup of creamy peanut butter, and 2 cups of powdered sugar until smooth. Then add 1 teaspoon of vanilla extract and enough milk to reach desired consistency.
Step 9: Frost the Cake
Once the brownie cake is cooled, spread the peanut butter frosting evenly over the top using a spatula.
Step 10: Serve and Enjoy
Cut the brownie cake into squares and serve. Best enjoyed with a glass of milk or your favorite beverage.
