For The Cake

  • 1 3/4 cups all-purpose flour
  • 2 cups sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 eggs, beaten
  • 1 cup milk
  • 1/2 cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water
  • 1 10.5-oz bag of mini marshmallows

For The Frosting

  • 1/2 cup butter, softened
  • 6 Tbsp milk
  • 3 cups powdered sugar
  • 1/4 cup unsweetened cocoa powder
  • 1 tsp vanilla extract
  • 1 cup chopped pecans or walnuts


To Make The Cake

  • Preheat your oven to 350ºF and grease a 13x9-inch pan with cooking spray.
  • In a medium bowl whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add in eggs, milk, oil, and vanilla extract and using an electric mixer, beat for 2 minutes. Slowly stir in boiling water then pour into prepared pan and cook until a clean toothpick inserted comes out clean, about 40 minutes. Top with marshmallows and place back in oven for one minute more. Remove from oven and cool.

To Make The Frosting

  • In a large bowl cream the butter with an electric mixer until light and fluffy. Add milk, powdered sugar, cocoa powder, and vanilla and beat until incorporated. Stir in chopped nuts.
  • Top cake with frosting and serve.


The nuts are optional in this cake but we love the crunch they give.
You can always make these into 24 cupcakes, cooking about 25 minutes.

Perfect Pairing

Serve this cake with a bit of Chicory Coffee.
