Ingredients

Scale

For the Cake

  • 1 box (15.25 oz) chocolate cake mix
  • 1/2 cup unsalted butter, melted
  • 1 cup water
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 cups mini marshmallows

For the Frosting

  • 1/2 cup unsalted butter
  • 1/4 cup milk
  • 1/4 cup cocoa powder
  • 2 1/2 cups powdered sugar
  • 1 tsp vanilla extract
  • A pinch of salt


Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan thoroughly to prevent sticking.
  2. Make the Batter: In a large bowl, combine the chocolate cake mix, melted butter, water, eggs, and vanilla extract. Mix until the batter is smooth and well blended.
  3. Bake the Cake: Pour the prepared batter evenly into the greased pan. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean, indicating the cake is fully baked.
  4. Add Marshmallows: Remove the cake from the oven and immediately sprinkle mini marshmallows evenly over the hot cake.
  5. Toast Marshmallows: Return the cake to the oven for an additional 5 minutes, allowing the marshmallows to puff up and develop a light golden color.
  6. Prepare the Frosting: While the cake is toasting, melt the butter for the frosting in a saucepan over medium heat. Stir in the cocoa powder and milk, and bring the mixture to a simmer.
  7. Finish the Frosting: Remove the frosting mixture from heat and whisk in the powdered sugar, vanilla extract, and a pinch of salt until the frosting is smooth, thick, and creamy.
  8. Frost the Cake: Allow the cake to cool for about 10 minutes, then pour the warm frosting evenly over the marshmallow layer. Spread gently to cover all marshmallows.
  9. Cool and Serve: Let the cake cool completely before slicing into 12 servings and enjoying this rich, gooey chocolate treat.

Notes

  • Use full-fat milk for a richer frosting texture.
  • Ensure the cake is slightly warm when adding the marshmallows so they melt properly.
  • For an extra chocolate boost, consider adding chocolate chips to the batter before baking.
  • Store leftovers covered at room temperature for up to 3 days or in the refrigerator for up to 5 days.
