Nutritional Benefits
Some people might raise their eyebrows at a cake recipe that calls for soda, but hear me out! While this Coca-Cola Cake isn’t necessarily a health food, there are some aspects to appreciate. For one, using buttermilk instead of regular milk adds a nice dose of calcium and gives the cake a deliciously tender crumb. Plus, it’s a fantastic treat that brings people together, creating memories that are worth every calorie!
Adaptable Variations
Want to make this cake a bit healthier? You can swap out some of the all-purpose flour for whole wheat flour to add a bit more fiber. And if you want to make it a bit lighter, try using unsweetened applesauce instead of vegetable oil (though it might alter the texture just a little). You can also play around with the types of cocoa powder you use—dark chocolate cocoa gives it an even richer flavor!

The Recipe
Ingredients
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup Coca-Cola (regular, not diet)
- 1/2 cup vegetable oil
- 1/2 cup buttermilk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup mini marshmallows (optional, for extra moisture)
- 1/2 cup butter (for the frosting)
- 1/4 cup Coca-Cola (for the frosting)
- 1/4 cup unsweetened cocoa powder (for the frosting)
- 4 cups powdered sugar
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
- In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt until well combined.
- In a saucepan, combine 1 cup of Coca-Cola, vegetable oil, and cocoa powder; bring to a boil over medium heat.
- Once boiling, pour the hot mixture into the dry ingredients and stir until fully combined.
- Add in the buttermilk, eggs, and vanilla extract. Mix until smooth. If you’re adding mini marshmallows, fold them in now!
- Pour the batter into the prepared baking pan, and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- While the cake is baking, let’s make the frosting! Melt the butter in a saucepan over medium heat.
- Add in 1/4 cup of Coca-Cola and 1/4 cup of cocoa powder, stirring until well blended.
- Remove from heat and mix in the powdered sugar until the frosting is spreadable and smooth.
- Once the cake is baked and has cooled for about 10 minutes, poke holes across the top with a fork to allow the frosting to soak in better.
- Pour the warm frosting over the warm cake, spreading it evenly to cover the surface.
- Let the cake cool completely in the pan before slicing and serving.
- Enjoy your delicious classic Southern Coca-Cola Cake!
