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

Instructions

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.

Notes

The frosting must be poured over the cake while both the cake and frosting are hot. This allows the frosting to seep slightly into the cake, creating the signature fudgy top layer that Coca Cola cakes are famous for.
