Ingredients
Brownie Base
- 1-1/2 cups butter, divided
- 3/4 cup baking cocoa, divided
- 4 large eggs, room temperature
- 2 cups sugar
- 1 teaspoon vanilla extract
- 1-1/2 cups all-purpose flour
- 1/2 teaspoon salt
Peanut Butter Layer
- 1 jar (16.3 ounces) chunky peanut butter
- 1/3 cup 2% milk
Marshmallow Topping
- 10 large marshmallows
- 2 cups confectioners’ sugar
Instructions
- Prepare Brownie Batter: Preheat your oven to 350°F (175°C). In a small saucepan, melt 1 cup of butter and stir in 1/2 cup of baking cocoa until smooth. Remove from heat. In a large bowl, beat the eggs, sugar, and vanilla extract until well blended. Combine the flour and salt, then gradually add this dry mixture to the egg mixture. Beat in the cocoa and butter mixture until fully incorporated.
- Bake Brownies: Transfer the batter evenly into a greased 15x10x1-inch baking pan. Bake in the preheated oven for 18-22 minutes or until a toothpick inserted in the center comes out clean. Remove from oven and allow to cool on a wire rack for 3-4 minutes.
- Spread Peanut Butter Layer: While the brownies are still warm, heat the chunky peanut butter in the microwave on high for about 30 seconds until softened. Stir well, then spread evenly over the warm brownies. Place the pan in the refrigerator to chill until the peanut butter layer is set, approximately 45 minutes.
- Prepare Marshmallow Topping: In a heavy saucepan, combine the remaining 1/2 cup butter, remaining 1/4 cup baking cocoa, marshmallows, and 1/3 cup 2% milk. Cook over medium-low heat, stirring constantly until the butter and marshmallows melt and the mixture becomes smooth. Remove from heat.
- Finish Topping and Chill: Gradually stir in the confectioners’ sugar into the marshmallow mixture until smooth and spreadable. Spread this marshmallow frosting evenly over the peanut butter layer. Refrigerate the entire brownie layered dessert for at least 30 minutes to set before cutting into squares and serving.
Notes
- Ensure eggs are at room temperature for better batter consistency.
- Do not overbake the brownies; they should be moist and fudgy.
- Use chunky peanut butter for texture contrast but smooth peanut butter can be substituted if preferred.
- Allow the peanut butter layer to fully set in the refrigerator to prevent mixing layers.
- Store brownies covered in the refrigerator for up to 3 days to maintain freshness.
