Buttermilk Substitute
No worries if you don't have buttermilk on hand, it can easily be substituted!
To substitute the buttermilk in this recipe, add ¾ cup of either white vinegar or lemon juice to a measuring cup and then add enough to milk to equal ¾ cup. Allow the mix to sit for roughly 10 minutes before adding it into the cupcake batter. This gives the ingredients a chance to mingle together.

Irish Cream Buttercream
This Irish cream buttercream is made with an American buttercream base and is made using basic ingredients.
- Unsalted Butter - room temperature
- Confectioner's Sugar
- Salt
- Irish Cream
- Milk - just enough milk to make the buttercream easy to pipe. About 2 to 4 tablespoons of milk added a little at a time.

How to Make Irish Cream Cupcakes
These cupcakes are pretty basic to make and pretty quick to make from start to finish.
The first step to making these cupcakes is to work with room temperature ingredients. Allow the butter and eggs come to room temperature before making the cupcake batter.
The unsalted butter is beat using a hand mixer until the butter is creamy. Once creamy, the granulated sugar is added. The room temperature eggs are then blended in and the batter will become light and fluffy. At this time the vanilla extract is added in as well.
After the eggs are beat into the batter the unsweetened cocoa powder is mixed in.
Next, the spooned & leveled all-purpose flour is mixed with the baking powder and baking soda. Half of he dry mixture is slowly beat into the wet ingredients.
The Irish Cream and milk is then added into the batter followed by the remaining dry ingredients.
The cupcake batter is then transferred to paper-lined cupcake pans.

Filling the Irish Cream Cupcakes
It is quite easy to fill cupcakes and you only need a piping bag and a Bismark Tip (or a piping tip with a open tip) to fill the cupcakes.
Once the cupcake filling is made, transfer the filling to a bag fitted with the piping tip.
There is no need to cut out the center of the cupcake, all you need to do is puncture the center of the cupcake with tip and squeeze the filling into the cupcake. Gently lift as you squeeze and pull away from the cupcake once you can see the filling of the cupcake start to ooze out of the top.
Once the filling is in all the cupcakes, it's time to make the Irish Cream buttercream frosting. I use a 1M piping tip fitted on a piping bag.

It's a good thing we keep Irish Cream handy at our house. We love the taste and when I saw this recipe I knew I'd be making it for our St. Paddy's day party. Of course I had to give it a trial run. Well, the cupcakes were super moist and that frosting is to die for. I'll definitely keep this recipe handy.
