Flashback to Leprechaun Patties from the blog. Arrrrr! Wait… Tee Hee! I’m not quite sure what noise a leprechaun makes, but whatever it is will be exactly the sound that you will be making after trying these delicious cookie sandwiches. A bit of Bailey's will perfectly accent the dark, sweetened chocolate sablé cookies with a smooth, creamy mint filling. Recipe on the blog.
