Introduction
Double Chocolate Coca Cola Cake is a legendary Southern dessert known for its incredibly moist texture, deep chocolate flavor, and rich, glossy chocolate frosting poured on while the cake is still warm. The Coca Cola might sound unusual, but it’s the secret ingredient that makes this cake unbelievably soft, tender, and full of flavor without tasting like soda.
This cake has been passed down through generations and is often served at potlucks, family gatherings, church dinners, and holidays. The carbonation in the Coca Cola helps create a lighter crumb, while the sweetness enhances the cocoa, giving the cake a bold, chocolate-forward taste. Adding chocolate both in the batter and the frosting turns this into a true double chocolate experience.
One of the best things about this cake is how easy it is to make. It’s typically baked as a sheet cake, mixed in one bowl, and topped with a warm pour-over frosting that sets into a fudgy layer. No layers, no fancy decorating—just pure chocolate comfort in every bite.
Ingredients
For the Cake
2 cups all-purpose flour
2 cups granulated sugar
½ teaspoon salt
½ teaspoon baking soda
1 cup unsalted butter
¼ cup unsweetened cocoa powder
1 cup Coca Cola (not diet)
½ cup buttermilk
2 large eggs
1 teaspoon vanilla extract
For the Chocolate Frosting
½ cup unsalted butter
¼ cup unsweetened cocoa powder
6 tablespoons Coca Cola
3 ½ cups powdered sugar
1 teaspoon vanilla extract
Preparation
Step 1: Prepare the Pan and Oven
Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan (or jelly roll pan for thinner cake) and set aside.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the flour, sugar, salt, and baking soda until well combined.
Step 3: Heat the Coca Cola Mixture
In a saucepan over medium heat, combine the butter, cocoa powder, and Coca Cola. Stir continuously until the butter is melted and the mixture is smooth. Bring just to a gentle boil, then remove from heat.
Step 4: Combine Wet and Dry Ingredients
Pour the hot cocoa-Cola mixture over the dry ingredients and stir until smooth. Add the buttermilk, eggs, and vanilla extract. Mix until the batter is fully combined and glossy.
Step 5: Bake the Cake
Pour the batter into the prepared pan and spread evenly. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
