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)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish. Set aside.

Step 2

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.

Step 3

Pour the batter into the prepared baking dish and smooth the top with a spatula.

Step 4

Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Step 5

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.

Step 6

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.

Step 7

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.

Step 8

Pour the warm frosting evenly over the marshmallow layer, spreading gently with a spatula to ensure coverage.

Step 9

Allow the cake to cool completely in the pan before slicing into squares and serving. Enjoy!
