Ingredients
Scale
Brownie Base
- 1 Family Sized Box of Ghirardelli Double Chocolate Brownie Mix
- Eggs (as required according to the brownie mix box instructions)
- Oil (as required according to the brownie mix box instructions)
- 1 cup Reese’s Peanut Butter Chips
Topping
- 1 batch of The Best Peanut Butter Buttercream Frosting
- 1/2 cup Semi-Sweet Chocolate Chips (for optional drizzle)
Instructions
- Prepare Brownie Batter: Follow the instructions on the Ghirardelli Double Chocolate Brownie Mix box to prepare the brownie batter, adding the required eggs and oil as specified. Once mixed, fold in 1 cup of Reese’s Peanut Butter Chips evenly into the batter.
- Bake Brownies: Pour the prepared brownie batter into a greased 13″ x 9″ baking pan. Bake according to the timing and temperature recommended on the brownie mix package. Allow the brownies to cool completely in the pan before proceeding.
- Make Peanut Butter Frosting: While the brownies cool, prepare a batch of The Best Peanut Butter Buttercream Frosting, which is rich, thick, and packed with peanut butter flavor. (Refer to the specific recipe for this frosting.)
- Frost Brownies: Once the brownies have cooled to room temperature, spread a generous and even layer of the peanut butter buttercream frosting over the top of the brownies using an offset spatula or knife.
- Optional Chocolate Drizzle: For an enhanced presentation and flavor, melt 1/2 cup of semi-sweet chocolate chips by placing them in a plastic bag and microwaving in short intervals until smooth. Carefully snip a very small corner of the bag and drizzle the melted chocolate over the frosted brownie bars. Let the chocolate drizzle set and harden before cutting and serving.
Notes
- Be sure to allow the brownies to cool completely before frosting to prevent the frosting from melting.
- The optional chocolate drizzle adds a decorative touch and extra chocolate flavor but can be omitted if desired.
- Using a family-sized boxed brownie mix makes this recipe quick and easy.
- The peanut butter buttercream frosting recipe is key to achieving the rich peanut butter flavor and creamy texture for this dessert.
