Ingredients
- 1 ½ cup (390 g) creamy peanut butter
- 1 cup (110 g) powdered sugar
- boxed brownie mix or plain brownie recipe, batter prepared according to instructions
Instructions
- In a bowl, mix peanut butter and powdered sugar until well combined.
- Place a piece of parchment in a 9 x 13 baking dish. Dollop the peanut butter mixture on top. Place another layer of parchment paper on top of the peanut butter mixture.
- Press the peanut butter into an even layer.
- Freeze for several hours, or overnight, until peanut butter is solid. Keep frozen until ready to use.
- Prepare the brownie batter according to package or recipe instructions.
- Spread ⅓ to ½ of the brownie batter into a prepared 9 x 13 baking dish.
- Peel one layer of parchment paper off of the frozen peanut butter layer. Place the peanut butter layer, peanut butter-side down, on top of the brownie batter.
- Peel away the remaining parchment paper. Spread remaining brownie batter on top.
- Bake according to package or recipe instructions.
Notes
Yield - this recipe makes enough of the peanut butter layer for a 9 x 13 batch of brownies. If your boxed brownies or plain brownie recipe is for an 8 x 8, either halve this recipe or double the brownies.
Baking dish - If you're using the same glass or ceramic baking dish to freeze the peanut butter and bake the brownies, make sure the baking dish comes to room temperature before baking to prevent it from cracking from the sudden temperature change.
