March is almost here, which means my mind is already thinking St. Patrick’s Day. This week I made Irish cream coffee cake. It’s tender, flavorful and spiked with Irish cream!

How have I not thought of this before? You have coffee spiked with Irish cream and you have coffee cake. It only seems natural to flavor the cake with Irish cream!

Turns out it’s pretty simple to do. Most coffee cakes call for some type of liquid, usually milk. And in my opinion the best coffee cakes calls for sour cream.

I wanted to keep sour cream as an ingredient while bringing in the Irish cream flavor. I decided to sub the milk with Irish cream hoping it would keep the moist texture, but add flavor.

Turns out that it works!

I will, however, be the first to admit that the Irish cream flavor is subtle. It’s not overwhelming at all since the recipe calls for only half a cup.

To add a little more flavor I decided to add a simple icing on top of the coffee cake. All it is is confectioners’ sugar and Irish cream (I like to use Bailey’s). I used a similar icing in my boozy Bailey’s cookies.

That extra Irish cream kick was exactly what these coffee cake squares needed!

The rest of the recipe is pretty straight forward. Layer the coffee cake with alternating layers of batter and streusel. By the way, the streusel is amazing. Can’t go wrong with brown sugar and butter, right?

To make it even simpler, I created a recipe video. I suggest turning on the volume to get you in the spirit for St. Patrick’s Day!
