Ingredients

1 box Betty Crocker™ Delights Super Moist™ Triple Chocolate Fudge Cake Mix
3/4 cup Guinness™ Draught Stout

3/4 cup butter, melted
1 large egg

2 large egg yolks
1 package (8 oz) cream cheese, softened

1/4 cup butter, softened
2 cups powdered sugar
3/4 cup cold heavy whipping cream

2 teaspoons vanilla

Instructions

Step 1: Heat the oven to 350°F. Grease a 9-inch round cake pan using shortening or cooking spray.
Step 2: In a large mixing bowl, whisk together the cake mix, Guinness stout, melted butter, egg, and egg yolks until the batter is smooth. Pour it evenly into the prepared pan.

Step 3: Bake for about 25 minutes, or until a toothpick inserted into the center comes out clean and the top springs back when lightly touched. Remove from oven and cool completely on a wire rack, about 1 hour.
Step 4: While the cake cools, beat the cream cheese, vanilla, and softened butter with an electric mixer on medium speed until smooth. Gradually add the powdered sugar in two batches, scraping down the bowl as needed. Slowly beat in the cold heavy cream until medium peaks form.
Step 5: Spread the frosting evenly over the cooled cake.

Step 6: Slice and serve. Store any leftovers in an airtight container in the refrigerator.

Tips & Variations

For extra moisture, substitute half of the Guinness with strong brewed coffee.
Try adding a teaspoon of instant espresso powder to the batter to enhance the chocolate flavor.

If you prefer, swap the cream cheese frosting with a classic chocolate ganache for a richer finish.

Storage

Store the cake in an airtight container in the refrigerator for up to 3 days. Before serving, you can let it sit at room temperature for about 30 minutes to soften. The frosting may be gently whipped again if it becomes too firm after refrigeration.

How to Serve

A single slice of dark chocolate cake sits in the center of a smooth white plate, showing two layers: a thick, moist chocolate base with a slightly crumbly texture and a thick, creamy layer of white frosting on top. The frosting has a smooth surface with gentle swirls that add a soft texture contrast. The plate rests on a white marbled surface, and a second slice of the same cake is blurred in the background on another white plate. The lighting emphasizes the rich color of the cake and the bright white frosting, creating a clean and simple look. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use a different type of stout or beer?

Yes, you can substitute Guinness with other stouts or dark beers, but keep in mind that the flavor profile may change slightly depending on the beer’s characteristics.

Is it necessary to use both egg yolks and whole eggs?

Using both adds richness and moisture to the cake, but you can use three whole eggs as a substitute if preferred, though the texture might be a bit less dense.
