It’s that time of year for everything green! At McDonald’s, that means you can get the famous Shamrock Shake! Creamy, minty ice cream, topped with fluffy whipped cream! So good!

I’ve been in the mood for whoopie pies and thought that making a Shamrock Shake version for St. Patrick’s Day would be so fun! So the experimenting began.

The first version I made, were a complete disaster. The cookies were too soft and too flat. They definitely would not hold up to the filling. So I made a few tweaks, and the result was so yummy!

The filling is a delicious blend of buttercream frosting and marshmallow cream with a hint of mint. Just like a Shamrock Shake! The best part of this recipe is how easy they are to make! Another easy treat for St. Patrick’s Day are Leprechaun Treats! Give them a try!
