Baileys Irish Cream filled Chocolate Whoopie Pies

Tomorrow is St. Patrick’s Day! On this St. Patrick’s Day eve I thought I’d post this recipe for Baileys Irish Cream Filled Chocolate Whoopie Pies. And I’ve got to tell you, these are possibly the best whoopie pies I’ve ever tasted.

The chocolate pie part is wonderfully moist with hints of the coffee and espresso flavours in the rich chocolate. But I think it’s the Baileys Irish Cream filling that has truly won my heart.

This filling is not your simple buttercream frosting, it is a Swiss Vanilla Buttercream, which I had never tasted before, much less made. It is to die for! Amazingly creamy and yet still light and fluffy. And when you add that Baileys Irish Cream into the mix…it is totally over the top!

I’m a huge fan and urge you to give it a try. I think you will be a convert too!

Baileys Irish Cream filled Chocolate Whoopie Pies

recipe from: Allison Eats

yield: 30 whoopie pies


for the pies:

  • 3 1/2 Cups All-Purpose Flour
  • 1/4 tsp Salt
  • 1 1/4 tsp Baking Powder
  • 1 1/4 tsp Baking Soda
  • 3/4 Cup Dark Unsweetened Cocoa Powder
  • 2 tsp Instant Espresso Powder
  • 1/2 Cup Hot Coffee
  • 2 Cups firmly packed Light Brown Sugar
  • 3/4 Cup Canola Oil
  • 1 Large Egg
  • 1 tsp Vanilla Extract
  • 1/2 Cup Buttermilk, shaken

for the filling:

  • 5 Large Egg Whites
  • 1 1/2 Cups Sugar
  • 2 Cups (4 sticks) Butter, cut into 1/2 inch cubes, cool but not cold
  • 1/4 tsp Salt
  • 3 Tablespoons Baileys Irish Cream


for the pies:

Preheat the oven to 350 degrees. Line 2 baking sheets with parchment paper (or grease them with oil).

In a large bowl, whisk together the flour, salt, baking powder, and baking soda, and set aside. In another large bowl, whisk together the cocoa powder and espresso powder. Add the hot coffee and 1/2 cup hot water, and whisk until both powders are completely dissolved.

In a medium bowl, stir the brown sugar and oil together. Add this to the cocoa mixture and whisk until combined. Add the egg, vanilla, and buttermilk and whisk until smooth.

Use a rubber spatula to gently fold the dry ingredients into the wet ingredients. Make sure to scrape down the sides and bottom of the bowl as you fold. Fill a piping bag with batter and pipe quarter-sized dollops 1-inch apart onto greased baking sheets. Bake for 10 minutes, until a toothpick inserted into the center of one whoopie comes out clean. Place whoopie’s onto wax paper to cool while you bake the remaining batches.

for the filling:

In a medium bowl, whisk the egg whites and sugar together. Set the bowl over a pan of simmering water but do not let the water touch the bottom of the bowl. Heat the mixture until the sugar is completely dissolved and the color is milky white, about 2-3 minutes.

Transfer the egg mixture to the bowl of an electric mixer fitted with the whisk attachment, and beat on medium-high speed (start slowly at first) until smooth and fluffy, about 5 minutes. Remove the whisk attachment and replace with the paddle attachment. Add the cubed butter and beat on medium-high speed (start slowly at first) until smooth and fluffy, about 5 minutes. If the buttercream looks like it is breaking, don’t worry, it will eventually come together.

Add the salt and Irish Cream and beat for 5 seconds to combine.

Pipe filling onto the flat sides of half of the whoopies and top with remaining half.
