Ingredients
  

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

Instructions
 

  • Preheat oven to 350°F (175°C) and grease a 9×13-inch baking pan.
  • Mix the cake mix, melted butter, water, eggs, and vanilla extract in a large bowl until smooth.
  • Pour the batter into the prepared pan and bake for 30–35 minutes, until a toothpick inserted comes out clean.
  • Remove cake from oven and immediately sprinkle mini marshmallows evenly on top.
  • Return cake to oven for 5 minutes, until marshmallows are puffed and lightly golden.
  • In a saucepan over medium heat, melt butter for the frosting, then stir in cocoa powder and milk.
  • Bring the mixture to a simmer, then remove from heat and whisk in powdered sugar, vanilla, and salt until smooth.
  • Let cake cool for about 10 minutes, then pour warm frosting over marshmallows and spread evenly.
  • Allow the cake to cool completely before slicing and serving.

Notes

  • Use coffee instead of water in the cake batter for a richer flavor.
  • Chopped pecans or walnuts can be added before frosting for added texture.
  • Store leftovers at room temperature for 2 days or refrigerate up to 5 days.
  • Microwave slices for 10–15 seconds to reheat.
