Irish cream coffee cake is the ultimate breakfast on St. Patrick’s Day. The cake is spiked with Irish cream and made with a brown sugar crumble.
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!

- 1/2 cup (60 g) confectioners’ sugar sifted
- 2 tablespoons (30 ml) Irish Cream
- Preheat the oven to 350° F. Line a 8-inch by 8-inch baking pan with parchment paper (or lightly grease with cooking spray). Set aside.

- With the mixer on medium-high, add eggs one at a time, beating until incorporated. Add vanilla and sour cream. Mix until combined.
- Turn mixer speed to low, add half the flour mixture and mix for a few seconds. Pour in Irish cream, mix for a few more seconds. Add remaining flour mixture and mix just until combined (careful not to overmix!) Scrape down the sides of the bowl with a rubber spatula as needed.
- Pour half the batter in prepared baking pan and spread evenly. Top with half the streusel mixture. Pour remaining batter on top (spread carefully if needed). Top with remaining streusel mixture.
- Bake for 40 minutes or until a toothpick inserted in the center comes out clean. Set pan on wire rack to cool for 15 minutes.
- In a small bowl, whisk together confectioners’ sugar and Irish cream. Drizzle over the cake. Slice and serve.
- Store sliced coffee cake in an airtight container at room temperature for up to 5 days.
