I like St. Patty’s alright, but it was never even close to a favorite holiday. It’s quickly becoming a fast favorite though, next to Thanksgiving and Christmas.

It’s hard not to like. It’s a big party, full of revelry and debauchery and jolliness. How can it not be fun?

For the last few years, we’ve spent our St. Patty’s in Buffalo, NY, at a big parade with all of my S.O.’s childhood friends. It’s a blast. We have the most incredible day of boisterous festivities.

March in Buffalo isn’t always the most ideal weather for spending a large part of the day outside at a parade, but when you’re surrounded by friends, good food, and plenty of Guinness and Bailey’s (and Jameson, for that matter), then you get okay with it.

The first year I went to the St. Patty’s parade in Buffalo, we started the day off at a friend’s bar. Somebody brought homemade Guinness cupcakes to the bar. That is how I want to start every Sunday afternoon – like St. Patty’s – with Guinness cupcakes and beer.

I think that particular St. Patty’s Day was 5 years ago now, but I have not forgotten those cupcakes, and it’s been my intention for a few years to recreate them. Finally, here we go.

These are devil’s food cake mix cupcakes with almost an entire bottle of Guinness thrown into them. They stay moist and light, and I love that the Guinness flavor adds so much to enhance the chocolate, but isn’t overwhelming or too bold. Bailey’s is such a nice complement to Guinness – or we wouldn’t have the Irish Car Bomb! But we do, thankfully.

The Bailey’s frosting is strong in Irish cream flavor and chocolate, and is creamy and fluffy.

The best part might be the chocolate ganache in the center. As soon as you take a bite, that gooey and rich center is such a welcome surprise!

There is no possible way that you won’t be the most popular person at a St. Patty’s Day party with a batch of these cupcakes in hand.
