Coca-Cola Cake

Two pieces of Coca Cola Cake with forks.

This Coco-Cola Cake is absolutely addictive. And I know because my daughter and I ate the whole thing by ourselves. I had originally made it for a friend’s birthday, but he unexpectantly left town and I couldn’t deliver it to him. My husband and son were in Montana for their annual Man Week, so my daughter and I snacked on it all week long.

This Coca-Cola Cake is easily one of the best chocolate cakes I’ve ever had, and I’ve eaten a lot of chocolate cake. The recipe is from ChocolateChocolate, my go to cookbook for chocolate recipes. I have never been disappointed with a recipe from this cookbook.

There is coke in both the batter and the frosting, and the cola helps produce an extra tender cake. The cake was still moist 5 days later when we ate the last crumb, and I didn’t even have it covered very well since I would grab a nibble practically every time I walked past it.

The recipe suggests making a second type of frosting, which I did. It’s very different tasting, much creamier and richer than the cola frosting and compliments the cake well. Plus if you pipe it on using a pastry bag, you can make the cake look much more fitting more a special occasion.

BUT- the cake would still be completely delicious without this second frosting.

Coca-Cola Cake - maybe the most moist and rich cake ever!

Cake Batter

  • ½ cup buttermilk
  • 1 teaspoon baking soda
  • ½ pound unsalted butter, cut into large chunks
  • 1 cup Coca-Cola
  • ¼ cup unsweetened alkalized cocoa powder
  • 2 cups bleached all-purpose flour
  • 2 cups superfine sugar
  • ½ teaspoon salt
  • 2 large eggs
  • 2 teaspoons vanilla extract

Coca Cola Frosting

  • 3 ¾ cups plus 2 tablespoons confectioners’ sugar
  • Large pinch of salt
  • 1 stick butter, melted and cooled to tepid
  • 2 ounces unsweetened chocolate, melted and cooled to tepid
  • 1 ¼ teaspoons vanilla extract
  • 6 tablespoons Coca-Cola, at room temperature

Chocolate Cookie Frosting

  • 4 cups confectioners’ sugar, or more if needed
  • 1/8 teaspoon salt
  • 6 ounces unsweetened chocolate, melted and cooled to tepid
  • 2 ½ teaspoons vanilla extract
  • ½ cup plus 1 tablespoon milk, heated to tepid
  • 8 tablespoons unsalted butter, softened


  • To make cake: Heat oven to 400º. Spray a 13x9x2-inch pan with cooking spray. Whisk the buttermilk and baking soda in a small nonreactive bowl. (The buttermilk will start to swell.)
  • In a medium saucepan, combine 2 sticks butter, 1 cup Coca Cola, and the cocoa powder and bring to a boil.
  • Meanwhile, place flour and 2 cups superfine sugar in a large mixing bowl fitted to an electric mixer and use the whisk attachment to sift them together. Pour the hot Coke mixture into the mixing bowl and mix on moderately low-speed until thoroughly combined, about 2-3 minutes.
  • Mix in the eggs, vanilla extract, and buttermilk mixture. Mix well to combine. Batter will be thin. Pour into prepared pan. Bake for 20 minutes, or until a toothpick inserted in the center comes out clean. Let cake cool for 5 minutes.
  • To make Coca Cola Frosting: Combine the confectioners’ sugar (3 3/4 cups plus 2 tablespoons) and a large pinch of salt in a large mixing bowl. In a small bowl whisk together butter and melted chocolate until smooth. (I melted them to together in a small saucepan over low heat.) Mix vanilla extract into chocolate mixture.
  • Pour the chocolate mixture over the confectioners’ sugar and add the 6 tablespoons of Coca Cola. Beat on low-speed for 1 ½ to 2 minutes, just until combined and smooth. Scrape down sides of the bowl to ensure everything is mixed evenly. Pour frosting over cake and use a rubber spatula to smooth it out.
  • To make Chocolate Cookie Frosting: Place 4 cups confectioners’ sugar and salt into a mixing bowl of an electric mixer fitted with a paddle attachment. Add melted chocolate, vanilla extract, and milk. Beat on medium-low speed for about 2 minutes.
  • Blend in butter 2 tablespoons at a time, beating just until incorporated. Increase speed to medium and beat until smooth, about 1-2 minutes. Scrape down sides of bowl periodically to keep frosting smooth.
  • Note: If frosting is too thick, add additional milk 2 teaspoons at a time (no need to warm this milk). If too thin, add additional confectioners’ sugar. Use a pastry bag to pipe frosting onto cake. Garnish with walnuts if desired.

  1. How about adding information on the best way to store these cakes, and how long they can be stored and still taste great.

  2. I would have never thought to use coca-cola in a cake – this is so different! And with two different kinds of frosting? Holy yum!
