Make Dough

1. In a stand mixer fitted with the paddle attachment, cream together butter & sugar until light & fluffy, about 5-7 minutes
2. Add egg & egg yolk one at a time & mix until combined
3. Add vanilla
4. Alternate adding in dry ingredients with mint chocolate liqueur until combined
5. Wrap dough in plastic & refrigerate at least 2 hours. (Meg recommends chilling the dough overnight)

Roll Out & Bake

1. Let the dough sit out at room temp before rolling it out
2. Sprinkle flour on your work surface so the dough doesn't stick
3. Using a rolling pin, roll the dough to about ¼" thick
4. Cut using cooking cutters and place on a parchment-lined cookie sheet
5. Refrigerate 20-30 minutes before baking
6. Bake 10-12 minutes at 350°, or until edges of cookies are golden

**You can cut your cookies ahead of time and freeze them in wax paper-lined tupperware. Put the frozen cookies straight into the oven & bake until golden.**

2. Pour over chocolate chips and whisk until combined

2. Transfer ganache into a piping bag
3. Fill & sandwich the cookies together
4. Refrigerate at least 15 minutes before decorating
