When it comes to dessert my Guinness Chocolate Cake will not disappoint! While traveling through Ireland I enjoyed quite a few slices of this delicious cake.

And although it doesn’t quite resemble the original version of an Irish stout cake, it’s been adopted wholeheartedly by Irish restaurateurs and pub owners. And for that I am grateful!

When you think of stout and the complex intensity of the brew, with its deep flavors, mixing it with chocolate, adds to the complexity and increases the depth of the chocolate….sigh. It’s a wonderful thing.

Let’s start by gathering the ingredients we need to make a Guinness Chocolate Cake. In Chef Speak this is called the “Mise en Place” which translates to “Everything in its Place”.

Not only does setting your ingredients up ahead of time speed the up cooking process, but it also helps ensure you have everything you need to make the dish.

Do I have to use Guinness in the cake recipe?

No, you can use any of your favorite dark beers or red wine to make this delicious cake. If you can’t have alcohol or would rather not include it in the recipe these are acceptable substitutes.

Root Beer
Black Coffee
Black Tea
Chocolate Milk

**Coffee will be the closest substitute that will bring out the deep chocolate notes. The alcohol will all burn off, and I promise no one will get drunk from the cake.

How do I make Guinness Chocolate Cake?

Start by preheating your oven to 350 degrees F.

Melt the butter in a saucepan over medium-low heat. Add the Guinness to the melted butter and bring to a simmer.
Remove the pan from the heat and stir in the cocoa powder. Mix well and allow to cool for 10 minutes.

Why is the cocoa added to the warm Guinness?

By adding the cocoa to the warm Guinness and letting sit for a few minutes, were allowing the cocoa to bloom. This step brings out the cocoa’s deep chocolate notes and helps create the rich chocolate flavors that this cake is known for.

Why do I melt the butter instead of creaming it with the sugar?

This is a different technique than most cakes call for. By melting the butter and adding it to the Guinness and cocoa, the butter now reacts to the mixture like oil and produces a soft moist crumb.

When the frosting is smooth and the cake has cooled, frost the top of the cake with the frosting. The cake should resemble a pint of Guinness.
