It comes together quickly thanks to Betty Crocker™ Super Moist™ Cake Mix and requires zero layering or fussy frosting techniques. Guinness stout takes the place of the liquid in this recipe and lends a complementary depth to the chocolate cake. This single-layer cake is finished off with a thick, billowy crown of smooth cream cheese frosting.

How to Make Easy Chocolate Guinness™ Cake

Here are our favorite tips for making the easiest Chocolate Guinness Cake. Follow the recipe for full details.

1. Make the Batter

Starting with Betty’s Super Moist Triple Chocolate Fudge Cake makes this recipe easy. We’ve altered the box recipe to make a rich and fudgy single-layer cake by swapping in Guinness stout, butter, and egg yolks for the water, oil, and eggs called for on the box. No fancy technique needed, simply mix everything together in a bowl until well combined.

2. Bake the Cake

Bake the cake until a toothpick inserted in the center comes out clean. The cake may rise in the center but fall a bit as it cools. This is okay, it will add to the dense, fudgy texture of the finished cake.

3. Frost the Cake

While the cake bakes and cools, make the fluffy cream cheese frosting. Feel free to swap out the vanilla with Irish cream liqueur—just a tablespoon will add a unique and complementary flavor to the frosting. Spread the frosting generously over the top of the cake in a thick layer. 

How to Store Easy Chocolate Guinness™ Cake

Follow these tips for storing this fudgy chocolate cake.

Refrigerator

Since this cake has cream cheese in the frosting, it needs to be stored in the refrigerator. Store the leftover cake loosely covered in plastic wrap or in a cake storage container for up to 3 days.

Freezer

Freeze the leftover cake, whether whole or in slices, until the frosting is firm. Then wrap well in plastic wrap and freeze for up to 1 month.

Thawing

Thaw the cake in the refrigerator overnight. Do not microwave as the frosting will melt and possibly burn.
