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
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan thoroughly to prevent sticking.
- 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.
- 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.
- Add Marshmallows: Remove the cake from the oven and immediately sprinkle mini marshmallows evenly over the hot cake.
- 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.
- 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.
- 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.
- 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.
- 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.
