Mocha Irish Cream Cupcakes for St. Patrick’s Day

It snowed this morning!! We have had almost no snow this year, and actually hit 80 degrees last week, and I was missing winter. But I woke up this morning to big wet snowflakes! That has absolutely nothing to do with these cupcakes, but I was so excited I just had to share. 🙂  

Anyway, on to the cupcakes! Do you guys do anything special for St. Patrick’s Day? Do you attend a parade, or bake anything special? I’ve never really celebrated it much, but a few weeks ago I was in Michaels, mostly just browsing, but with my Cherry Chocolate Chip Rolls in mind. I was supposed to be looking for something Valentine’s Day related while I was walking down the baking aisle, and then I spotted these St. Patrick’s Day sprinkles.


I decided I had to have them, but then I had to figure out what to do with them. Cupcakes sounded like a good idea, but what kind? So I started searching Pinterest for St. Patrick’s Day ideas. It seems like Irish cream is pretty popular right now. And since Irish cream has a lot of the same flavors as mocha, I decided to incorporate in into a favorite mocha cake of mine. And make them cupcakes, because cupcakes are just more fun.

I thought it might be easier (and cheaper!) to use an Irish cream coffee creamer. Since I don’t drink coffee, I had never tried the creamer before. Before I started trying to add it to my cake recipe, I tried it straight. Oh my goodness, you guys, it is SWEET. So I knew immediately I would have to reduce the sugar in the recipe. Thankfully, it turned out perfectly on my first attempt, but I sure am glad I tried the creamer first!

To top the cupcakes, I figure I might as well go all the way and make an Irish Cream buttercream. It was a good idea. The cupcakes aren’t overly sweet, so a nice big swirl of buttercream compliments them nicely. And it gives the sprinkles a pretty place to land. 🙂

If you aren’t a fan of Irish cream, or coffee in general, you can make some adjustments to this recipe pretty easily. Try any flavor of creamer that sounds good to you. And if you are using a non-mocha flavoring you can leave the instant coffee out of both the cake and frosting. Amaretto would be fantastic (I LOVE chocolate and almond together!). You can amp up the flavor by adding a little bit of almond extract. Or what about the salted caramel mocha? I might add some salted caramel into the buttercream for that one. A peppermint or peppermint mocha version would be fantastic at Christmas! For now, I’m going to stick with the Irish cream, but I definitely have other ideas brewing! 😉

Recipe Notes

Buttercream makes enough to generously frost 24 cupcakes. If you prefer a smaller layer of frosting, cut recipe in half.

Substitute any flavor creamer for the Irish cream, eliminating the instant coffee granules if preferred. Enhance with extracts if desired. Almond in Amaretto, peppermint in peppermint mocha, etc.
