Heat your oven to 350 degrees. In a large bowl, sift the sugar and flour together, then add the marshmallows. In a saucepan, mix the butter or margarine, oil, cocoa, and Coca-Cola. Bring all of this a boil and pour it over the dry ingredients, and mix until well blended. Dissolve the baking soda in the buttermilk just before adding it to the rest of the batter, along with the eggs and vanilla extract. Mix everything well, and pour into a well-greased 9 x13 inch pan. Bake the cake for 35-45 minutes, and frost it as soon as it comes out of the oven!

Coca-Cola Cake Frosting

Of course you can buy your own frosting, but if you’re committed to baking this cake from scratch you’ll need to make the frosting too! It’s very simple, and definitely worth it.

Ingredients

½ cup of butter

3 tablespoons of cocoa

6 tablespoons of Coca-Cola

1 box (or 16 oz) of confectioners sugar

1 teaspoon of vanilla extract

1 cup of chopped pecans

Directions

Combine the butter, cocoa, and Coca-Cola in a saucepan. Bring it all to a boil and pour it over the confectioners sugar, blending everything well. Add the vanilla extract and pecans. Spread it over your cake when it’s fresh out of the oven, let it cool, and serve in squares!
