Mint Chip Ice Cream Sandwiches

Preheat the oven to 375F.

In a medium bowl, cream together the butter, shortening and sugar. Once fluffy, add the egg yolk and vanilla and beat to combine. Set aside.

In a small bowl, combine all remaining ingredients (except the ice cream, duh), whisking well. Sprinkle about 1/2 of the mixture over the butter and sugar mixture, beat until combined, then sprinkle in the rest. Beat until just combined–do not overmix.

Scoop your cookies and roll them into balls in your hands. Use 2 teaspoons of dough for small cookies or 1 heaping tablespoon of dough for larger cookies. Place them evenly on a baking sheet lined with parchment paper (or a silicone mat) and bake for 9-12 minutes, depending on size of cookie. They are done when they start to crack on top. Remove them from the oven and let them cool on sheet for 1 minute before moving cookies to a wire rack to cool completely.

When ready to serve, place 1 large scoop of ice cream on the bottom of 1 cookie and top with another cookie. If there are leftovers, wrap the sandwiches in plastic wrap and freeze them. Let them thaw for a few minutes before eating.
