This Guinness Chocolate Cake is rich and indulgent with a slight Guinness flavor and thick chocolate frosting on top!

Guinness Chocolate Cake with a beer

all about Guinness Chocolate Cake

As much as I want to tell you that this super indulgent Guinness Chocolate Cake is just for St Patrick’s Day, I’d be doing you a disservice. Because if you can find Guinness at the store, I recommend you make this cake for any time you need a serious chocolate fix!

Yes, it has beer in it but it gets cooked off in the process and leaves only a very mellow flavor which the thick rich chocolate frosting takes away in a few seconds. So apart from feeling ultra sad when the cake is gone, no other effects will be noticeable unless you eat it with a beer or two (or three) to celebrate your St Patrick’s Day dinner!

Talking of dinner, this cake would be the perfect end to a corned beef and cabbage meal. Or try and leave some room for a traditional Irish coffee paired with a slice of Guinness Chocolate Cake.

Spreading frosting on my Guinness Chocolate Cake

making your chocolate cake

The cake is denser than a regular light and fluffy cake, and it’ll rise and then fall a bit when it’s cooling. Don’t worry though because once you cover it with my easy chocolate frosting I stole from this amazing Chocolate Peanut Butter Pie, you’ll be well on your way to a second piece.

Make sure to enjoy your Chocolate Cake at room temperature and not straight from the fridge. I want you to experience that melt in your mouth sensation which will never happen if the cake is chilled.

Happy St Patrick’s Day friends and remember to tag me on Instagram (@foodnessgracious) if you make this cake!
