How to Make (Step-by-Step Instructions)
Step 1: Prepare the Brownie Batter
Preheat your oven to 175°C (350°F). In a bowl, mix melted butter and sugar until smooth. Add eggs and vanilla, then whisk until glossy.
Step 2: Add Dry Ingredients
Stir in cocoa powder, flour, salt, and baking powder. Mix just until combined—avoid overmixing to keep the brownies fudgy.
Step 3: Bake the Brownie Base
Pour the batter into a lined or greased 9×9-inch pan. Bake for 20–25 minutes. Let the brownies cool completely before adding layers.
Step 4: Make the Peanut Butter Layer
In another bowl, beat peanut butter, softened butter, powdered sugar, and vanilla until smooth and thick. Spread evenly over the cooled brownie base.
Step 5: Prepare the Chocolate Topping
Melt chocolate chips and butter together using a microwave or double boiler. Stir until smooth and glossy.
Step 6: Assemble and Chill
Pour the melted chocolate over the peanut butter layer and spread evenly. Refrigerate for about 1 hour until set. Slice into squares and serve.
Tips for Best Results
Getting clean layers and balanced flavor comes down to a few key details:
-
