This Double Fudge Coca Cola Cake tastes even better than the one at Cracker Barrel and is easy to make since it starts with a boxed cake mix!

For the cake:

  • 1 box chocolate fudge cake mix
  • 1 (4 oz) (small box) instant chocolate pudding
  • 3 eggs
  • 1/3 cup oil
  • 1 cup Coca-Cola

For the frosting:

  • 1 stick salted butter, (1/2 cup)
  • 3 tbsp unsweetened cocoa
  • 4-6 tbsp heavy cream or milk *see notes below
  • 2 cups powdered sugar
  • 1 tsp vanilla extract
  • 1/2 cup chopped pecans or walnuts, optional


For the cake:

  • Preheat oven to 350F degrees.
  • Spray 9 x 13 baking pan with nonstick cooking spray.
  • In a large bowl, with an electric mixer, stir together cake mix, dry pudding mix, eggs, oil and Coke for about 2 minutes on medium speed.
  • Pour batter into prepared baking dish and bake according to package directions (usually 35-40 minutes). Note: The cake will have a slight dip in the center. This is normal. When it is done, a toothpick will come out clean.

For the frosting:

  • In a medium saucepan, over medium-low heat, start melting butter.
  • Add in cocoa powder and heavy cream (or milk, if using) and stir.
  • Then whisk in confectioners sugar. Stir briskly with a whisk to get all the lumps out.
  • Take mixture off heat and stir in vanilla extract.
  • Pour frosting over cake and evenly spread it out over cake.
  • Sprinkle chopped nuts on top, if using. I think this cake is best served warm with a scoop of vanilla ice cream. 



If you are using milk instead of heavy cream, you will probably only need about 3-4 tbsp. of it because milk is thinner than heavy cream. Just use your judgement on it. Start with less and add a little at a time to get the right consistency. Or, you can always add a bit more powdered sugar to the frosting to make it thicker if you like.
