Ingredients

• 1 cup unsalted butter
• 1 cup semi-sweet chocolate chips
• 1.5 cups granulated sugar
• 4 large eggs
• 2 teaspoons vanilla extract
• 1 cup all-purpose flour
• 0.25 cup unsweetened cocoa powder
• 0.5 teaspoons salt
• 2 cups marshmallow fluff
• 0.5 cup heavy cream
• 1.5 cups semi-sweet chocolate chips (for glaze)
• 2 tablespoons unsalted butter (for glaze)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and line a 9x9-inch baking pan with parchment paper, leaving an overhang for easy removal.

Step 2

In a medium saucepan, melt the 1 cup of unsalted butter and 1 cup of semi-sweet chocolate chips over low heat. Stir constantly until smooth. Remove from heat and allow to cool slightly.

Step 3

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

Step 4

Gradually stir the melted chocolate mixture into the egg mixture until fully incorporated.

Step 5

Sift together the all-purpose flour, cocoa powder, and salt. Gently fold the dry ingredients into the wet mixture, being careful not to overmix.

Step 6

Pour the brownie batter evenly into the prepared baking pan. Smooth the top with a spatula.

Step 7

Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let the brownies cool completely in the pan on a wire rack.

Step 8

Once the brownies have cooled, spread an even layer of marshmallow fluff (about 2 cups) over the top. Use a spatula to smooth it out.

Step 9

To prepare the chocolate glaze, heat the heavy cream in a small saucepan over medium heat until it begins to simmer. Remove from heat and add the 1.5 cups of semi-sweet chocolate chips and 2 tablespoons of unsalted butter. Let sit for 2 minutes, then stir until smooth and glossy.

Step 10

Pour the chocolate glaze over the marshmallow layer, spreading it out evenly with a spatula or the back of a spoon.

Step 11

Refrigerate the pan for at least 1 hour, or until the glaze is set.

Step 12

Once chilled, use the parchment paper overhang to lift the brownies from the pan. Slice into 16 squares and serve. Enjoy!
