Recipe Information
Ingredients
- 1 cup unsalted butter (for cake)
- 2 cups granulated sugar
- 1.5 cups all-purpose flour
- 0.25 cup unsweetened cocoa powder
- 4 large eggs
- 2 teaspoons pure vanilla extract
- 0.5 teaspoon salt
- 10 ounces mini marshmallows
- 0.5 cup unsalted butter (for frosting)
- 0.25 cup unsweetened cocoa powder (for frosting)
- 0.25 cup milk
- 2 cups powdered sugar
- 0.5 cup chopped pecans or walnuts (optional)
Instructions
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish. Set aside.
In a large saucepan over medium heat, melt 1 cup of butter. Remove from heat and stir in 2 cups of granulated sugar, 1.5 cups of all-purpose flour, 1/4 cup of unsweetened cocoa powder, 4 large eggs, 2 teaspoons of vanilla extract, and 0.5 teaspoon of salt. Mix until smooth.
Pour the batter into the prepared baking dish and smooth the top with a spatula.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Once the cake is out of the oven, immediately sprinkle the 10-ounce bag of mini marshmallows evenly over the hot cake. Set aside to allow the marshmallows to soften and slightly melt while you prepare the frosting.
In a medium saucepan, melt 0.5 cup of butter over medium heat. Stir in 1/4 cup of unsweetened cocoa powder and 1/4 cup of milk. Allow the mixture to come to a gentle simmer, stirring constantly.
Remove the saucepan from heat and whisk in 2 cups of powdered sugar until the frosting is smooth. If using, fold in 0.5 cup of chopped pecans or walnuts.
Pour the warm frosting evenly over the marshmallow layer, spreading gently with a spatula to ensure coverage.
Allow the cake to cool completely in the pan before slicing into squares and serving. Enjoy!
