A Traditional Coca Cola Cake Recipe

Yes, you can even make chocolate cake using Coca-Cola! Here's how to make a classic Coca-Cola cake from scratch.

You may have heard of soda being used in recipes like pot roast, but did you know Coca-Cola is actually delicious in a cake as well? This sweet soda is the perfect addition to a homemade chocolate cake.

The traditional way to make Coca-Cola Cake

According to Coca-Cola's classic recipe, traditionally Coca-Cola cake is frosted while the cake is still hot. You're supposed to pour the frosting mixture onto the cake while it is still warm from the oven.

However, after a few attempts at making the Coca-Cola cake, I found that this technique didn't go exactly as planned. Pouring warm frosting onto a warm cake means the frosting will seep into the cake, creating a moister (and sweeter) cake than you may have anticipated. This may sound unappealing, but after having a few friends and some of our Eat This, Not That! editors try the cake, numerous people expressed their satisfaction with such a sweet confectionary.

Personally, I feel waiting for the cake to cool a bit before frosting it would be best. However, if you would like to make a Coca-Cola cake in the traditional manner, pouring the frosting while the cake is still warm the way to go.

Pour cake mixture into a greased pan

Grease a 9×13" pan by coating the pan with some butter. You can easily do this by unwrapping part of a stick and drawing on the pan with butter until it is coated. Pour in the whisked cake mixture into the bowl, then bake it for 40-45 minutes. To make sure the cake is done, use a toothpick in the center. If it comes out clean, it's good to go!

5

Make the frosting

To make the frosting, cook the Coca-Cola in a pot for at least 10 to 12 minutes, or until the soda has reduced to half the size. Add in the butter and the cocoa powder, then whisk together. Once it starts boiling, add the sauce to a bowl with four cups of powdered sugar and whisk until smooth.

6

Pour frosting onto the cake

While the frosting is warm, pour it onto a cooled cake. If the cake isn't fully cool, that is okay! You're supposed to pour frosting onto a warm Coca-Cola cake. But for this recipe, I find waiting for the cake to slightly cool gives you the best result.
