Double Chocolate Coca Cola Cake Recipe Details:

  • Preparation time: 20 minutes
  • Cooking time: 30-35 minutes
  • Servings: 12-15
  • Equipment: 9x13-inch baking pan, saucepan, mixing bowls

This decadent dessert brings together the unexpected magic of Coca Cola and rich chocolate in one unforgettable cake.

Ingredients:

For the Cake Base:

  • 1 cup Coca Cola (not diet)
  • ½ cup buttermilk
  • 1 cup unsalted butter
  • ½ cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 and ½ cups mini marshmallows

For the Chocolate Coca Cola Frosting:

  • ½ cup unsalted butter
  • ¼ cup unsweetened cocoa powder
  • ⅓ cup Coca Cola
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 cup chopped pecans or walnuts (optional)

Directions:

  1. Preheat your oven to 350°F. Carefully prepare a 9x13-inch baking pan by greasing it or lining with parchment paper for easy removal.
  2. In a medium saucepan over medium heat, combine the Coca Cola, buttermilk, butter, and cocoa powder. Stir occasionally until the butter melts completely and the mixture becomes smooth and well combined.
  3. Remove the liquid mixture from heat and let it cool slightly. This step ensures the eggs won't scramble when added to the batter.
  4. In a large mixing bowl, whisk together the granulated sugar, flour, baking soda, and salt. Ensure all dry ingredients are evenly distributed.
  5. Gradually pour the slightly cooled Coca Cola mixture into the dry ingredients. Stir gently to combine, being careful not to overmix.
  6. Add the eggs and vanilla extract, mixing until just incorporated. The key is to maintain a light, tender texture.
  7. Gently fold in the mini marshmallows. They'll create magical pockets of gooey goodness during baking.
  8. Transfer the batter to the prepared baking pan, spreading it out evenly. Tap the pan lightly on the counter to remove any large air bubbles.
  9. Bake for 30 to 35 minutes. The cake is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs.
  10. While the cake bakes, prepare the frosting. In a medium saucepan, combine butter, cocoa powder, and Coca Cola over medium heat.
  11. Stir until the butter melts and the mixture becomes smooth. Remove from heat and gradually whisk in the powdered sugar and vanilla extract.
  12. If using, fold in the chopped nuts to the frosting.

Ready to Indulge!

Remove the cake from the oven and immediately pour the warm frosting over the hot cake. Use a spatula to spread it evenly, allowing the frosting to seep into every delicious crevice.

Storage Solutions:

  • Store covered at room temperature for up to 3 days
  • Keep in an airtight container to maintain moisture
  • Can be refrigerated for up to 5 days
  • Bring to room temperature before serving for best flavor
  • Freezes well for up to 1 month when wrapped tightly

Whether you're a chocolate lover or a curious baker, this Double Chocolate Coca Cola Cake delivers an unexpected twist that will have everyone asking for your secret recipe.
