Recipe Information
Ingredients
- 0.5 cup unsalted butter
- 1 cup granulated sugar
- 0.5 cup light brown sugar (packed)
- 2 units large eggs
- 1 teaspoon pure vanilla extract
- 1.5 cups all-purpose flour
- 0.5 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 0.25 teaspoon salt
- 3 cups mini marshmallows
- 1.5 cups semi-sweet chocolate chips
- 0.75 cup creamy peanut butter
- 2 tablespoons unsalted butter (for topping)
- 1.5 cups rice cereal (like Rice Krispies)
Instructions
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan or line it with parchment paper.
In a large bowl, cream together 1/2 cup butter, 1 cup granulated sugar, and 1/2 cup light brown sugar until light and fluffy.
Beat in the eggs, one at a time, followed by the vanilla extract.
In a separate bowl, combine the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until fully combined.
Spread the batter evenly into the prepared pan. Bake in the preheated oven for 18-20 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs.
Immediately sprinkle the mini marshmallows evenly over the hot chocolate base. Return the pan to the oven for an additional 2-3 minutes, or until the marshmallows are soft and slightly puffed. Remove from the oven and let cool completely.
In a small saucepan or microwave-safe bowl, melt the semi-sweet chocolate chips, peanut butter, and 2 tablespoons of butter until smooth. Stir in the rice cereal until fully coated.
Gently spread the chocolate-peanut butter mixture over the cooled marshmallow layer, ensuring it covers the entire surface.
Refrigerate the bars for at least 2 hours, or until the topping is firm.
Once set, slice into 16 bars and serve. Enjoy!
