Ingredients

• 1 cup unsalted butter
• 1.5 cups semi-sweet chocolate chips
• 1.5 cups granulated sugar
• 4 large eggs
• 2 teaspoons vanilla extract
• 1.25 cups all-purpose flour
• 0.25 cup unsweetened cocoa powder
• 0.5 teaspoon salt
• 3 cups mini marshmallows
• 1.25 cups milk chocolate chips
• 0.75 cup creamy peanut butter
• 2 cups crisp rice cereal

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease or line a 9x13-inch baking pan with parchment paper.

Step 2

In a microwave-safe bowl, melt the unsalted butter and 1.5 cups of semi-sweet chocolate chips in 30-second intervals, stirring well between each interval, until smooth. Let it cool slightly.

Step 3

In a large mixing bowl, whisk the granulated sugar, eggs, and vanilla extract together until well combined.

Step 4

Gradually mix the melted chocolate-butter mixture into the sugar-egg mixture until smooth.

Step 5

Sift together the all-purpose flour, unsweetened cocoa powder, and salt in a separate bowl. Gradually fold the dry ingredients into the wet mixture, stirring until no streaks remain.

Step 6

Pour the brownie batter into the prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted near the center comes out with moist crumbs. Allow the brownies to cool slightly in the pan.

Step 7

Once the brownies have cooled for 10 minutes, evenly spread the mini marshmallows over the top of the brownies. Return the pan to the oven for 3-5 minutes, until the marshmallows puff up but do not brown. Remove from the oven and let cool completely.

Step 8

In a microwave-safe bowl, melt the milk chocolate chips and creamy peanut butter together in 30-second intervals, stirring well between each interval, until smooth.

Step 9

Stir the crisp rice cereal into the melted chocolate-peanut butter mixture until evenly coated.

Step 10

Spread the rice cereal mixture evenly over the cooled marshmallow layer. Gently press into an even layer with a spatula or the back of a spoon.

Step 11

Refrigerate the pan for at least 2 hours, or until the topping is firm and set.

Step 12

Once set, slice the bars into 16 squares or desired serving sizes. Serve and enjoy!
