Ingredients
  

  • 1 cup finely chopped pecans
  • 1 teaspoon flour
  • 1 box chocolate cake mix prepared according to package directions
  • 1 cup brewed coffee
  • 1 (16 oz) package mini marshmallows
  • ½ stick butter, softened
  • 3 cups powdered sugar
  • cup cocoa powder
  • cup milk

Instructions
 

  • Preheat oven to 350°F. Spray a 13x9 inch pan with cooking spray.
  • In a small bowl, stir together the pecans and flour.
  • Prepare cake mix according to package directions, but substitute brewed coffee for the water that’s called for on the package. Stir in the flour-coated pecans.
  • Bake the cake according to package directions, but underbake by 5 minutes.
  • Remove from the oven and pour the mini marshmallows over the top. Place the pan back in the oven for 5 minutes, or until the marshmallows are very lightly toasted.
  • Let the cake cool completely.
  • Place the softened butter, powdered sugar, cocoa powder, and milk in a large bowl. Beat with a hand mixer until smooth and fluffy.
  • Spread over the cake. Let sit for several hours until the frosting firms up slightly (or refrigerate for 30 minutes). Cut into slices and serve.
