Recipe Information
Ingredients
- 0.75 cup unsalted butter
- 1.5 cups granulated sugar
- 0.5 cup light brown sugar
- 4 pieces large eggs
- 2 teaspoons vanilla extract
- 1 cup all-purpose flour
- 0.5 cup unsweetened cocoa powder
- 0.5 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 2 cups mini marshmallows
- 0.75 cup chopped pecans or walnuts
Instructions
Preheat your oven to 350°F (175°C). Grease and line a 9x13-inch baking dish with parchment paper, leaving an overhang for easy removal.
In a microwave-safe bowl, melt the butter in 20-second intervals until fully liquefied. Let it cool slightly.
In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth and well combined.
Add the eggs, one at a time, whisking well after each addition. Stir in the vanilla extract.
In a separate bowl, sift together the flour, cocoa powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until combined. Be careful not to overmix.
Fold in the chocolate chips until evenly distributed throughout the batter.
Pour the batter into the prepared baking dish and spread it out evenly with a spatula.
Bake in the preheated oven for 25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Remove the brownies from the oven and immediately sprinkle the mini marshmallows evenly over the top. Bake for an additional 3-5 minutes, just until the marshmallows puff up and start to melt slightly.
Remove the brownies from the oven again and sprinkle the chopped nuts over the top of the marshmallows, pressing them down gently with the back of a spoon.
Let the brownies cool completely in the pan on a wire rack. Once cooled, use the parchment overhang to lift the brownies out of the pan and onto a cutting board.
Cut into 16 squares and serve. Enjoy your Rocky Mountain Brownies!
