In case you hadn’t taken notice, St. Patrick’s Day is this weekend. I love all the glittery shamrocks, leprechauns, and Irish booze. What better way to mark the occasion than by baking cupcakes laced with two of the green isle’s two favorite spirits? Bailey’s and Guinness.

A quick Google led to several different variations. Many recipes called for a whiskey ganache filling for the cake, which sounded divine, but I was kind of pressed for time.  So, I went with a basic recipe for a moist, chocolate Guinness cake topped with a Bailey’s buttercream frosting.

I made these for my ladies book club that I hosted last Friday night, and everyone really enjoyed them. There is just enough of a boozy bite from the frosting to give it a kick, and the Guinness cake was just perfect – light, airy, and moist. I was honestly a bit worried about the cupcakes before putting them in the oven. With a whole bottle of beer in the batter, it’s very thin. Next time I might try using a batter bowl to fill the cupcake liners, instead of a scoop. Whether you’re creating an Irish celebration at home this St. Patty’s Day, or going out for a wild night on the town…try to squeeze in some time to make these cupcakes!

    They were so delish. Jimmy ate both of them that night. He let me taste a bite and they were wonderful. Thanks.

    I can’t wait to try these. I really wanted to do them for St. Paddy’s Day, but I didn’t have time. Probably for the next big event though. Thanks for sharing!

      It’s 12 ounces, Jen. Which would be about 355 ml.

    I made the cupcakes yesterday. After a day the flavors had melded, and they were wonderful. I added some espresso powder.
    There seem to be a discrepancy in the contents of a bottle (I used Guinness draught), per website it has 12 fl.oz, but the tag on the bottle says 11.2. That makes quite a difference for a cake batter, 24 ml. I made half of the recipe, and took 6 fl. oz. When the cupcakes came out of the oven, they were so wet and soft (not underbaked), that I almost considered them a failure, but set after some hours somewhat, so that I could frost them. (I used a Bailey’s cream cheese frosting.)
    I will definitely make them again, but with a little less liquid.
    Half the recipe amount yielded more than 13 cupcakes (3/4 filled).

    I’m making these next week. They look amazing! Could you tell me if they require refrigeration after being frosted? It’s a humid 94 degrees here.

      In your case, I probably would. Then just let them warm up a little bit on the counter before you enjoy them!
