Ingredients
The Cake Batter:
- 2 cups flour
- 2 cups sugar
- 1 cup butter or margarine
- 3 tablespoons cocoa
- 1 cup Coke
- ½ cup buttermilk
- 2 eggs (slightly beaten)
- 1 teaspoon baking soda
- 1 teaspoon vanilla
- 1 ½ cups miniature marshmallows
The Warm Fudge Frosting:
- ½ cup butter or margarine
- 3 tablespoons cocoa
- 6 tablespoons Coke
- 1 box powdered sugar (10x sugar)
- 1 cup nuts (chopped, optional)
Baking Instructions
🌡️ Oven Temp: 350°F
- Prep the Dry Base: Preheat your oven to 350°F. Grease a 9×13×2-inch baking pan. In a large mixing bowl, combine the 2 cups of flour and 2 cups of sugar; set aside.
- Boil the Chocolate Mix: In a saucepan over medium heat, bring 1 cup of butter, 3 tablespoons of cocoa, and 1 cup of Coke to a rolling boil. Pour this hot mixture directly over your flour and sugar blend, stirring well to combine.
- Finish the Batter: Mix in the buttermilk, slightly beaten eggs, baking soda, vanilla, and miniature marshmallows until just incorporated.
- Bake: Pour the smooth batter into your prepared pan and bake for 30 to 35 minutes.
- Prepare & Apply Frosting: While the cake finishes baking, prepare the frosting. Bring ½ cup of butter, 3 tablespoons of cocoa, and 6 tablespoons of Coke to a boil in a clean saucepan. Immediately pour the hot liquid over the box of powdered sugar and beat dynamically until completely smooth. Stir in the chopped nuts if desired, then pour and spread the hot icing over the warm cake straight out of the oven.
