Coca Cola Cake
This moist Coca Cola Cake is a classic chocolate cake recipe that is sure to please! It is a bit milder than most of our chocolate cakes, with wonderful flavor and texture. The Coca Cola in the recipe adds subtle flavor while also creating an extra tender cake (thanks to the added carbonation and boost of acidity).

Instructions
For the cake
- Preheat the oven to 350 degrees F, and grease and flour three 8 inch cake pans. We like to line the bottom of the pans with parchment paper.
- Sift the flour and sugar into a large heat-proof bowl/mixing bowl, add the baking soda, and whisk to combine. Add the marshmallows. Set to the side.
- Next, in a saucepan, add the butter, oil, cocoa powder, and coca cola. Bring the mixture to a boil over medium-high heat. Then, pour this hot mixture over the dry ingredient mixture. Mix on low speed just until combined. (We used an electric hand mixer for this).
- Next, pour in the buttermilk, eggs, and vanilla. Mix on low speed again, just until combined.
- Divide the batter between the three prepared pans. Bake for 18-20 minutes (Start checking at the 15 minute mark and adjust time as needed). When a toothpick can be inserted and comes out clean or with just a few crumbs attached, they are done.
- Allow the cakes to cool in the pans on a wire rack for 10 minutes before turning out. (Many of the marshmallows will dissolve during baking, but you may have others that have softened but are still visible on top of the cake layers.)
For the Coca Cola Buttercream
- Add butter and mix on low to medium speed until smooth. Add vanilla and blend into the butter. Add powdered sugar, salt, and cocoa powder.
- Add most of the Coca Cola. Begin mixing at low speed so you won't have a cloud of powdered sugar in your kitchen.
- Continue to mix adding remaining Coca Cola as needed. It may take 5 to 6 minutes to reach the smoothness and consistency you like. It will take longer if using a hand mixer. As you mix the frosting will become very smooth. You can add additional Coca Cola or milk (1 Tablespoon at a time) if the frosting is too thick or additional powdered sugar if too soft.
Notes
Substitution for buttermilk: Add 2 teaspoons of white vinegar or lemon juice to the ½ cup of buttermilk and allow to sit for 5-10 minutes until slightly curdled.
For the buttercream, if you prefer a slightly creamier consistency, you can swap in milk or cream for part of the Coca Cola amount.
