Step 1

With an electric mixer, cream the butter with the sugar until the mixture is light and fluffy. Add in mint extract and coloring.

Step 2

Add flour, baking powder, and salt. Mix until it forms a dough.

Step 3

Divide the dough in half. On a sheet of wax paper, form each half into an 8-inch log. Chill the logs, wrapped in the wax paper, for at least 2 hours or overnight. (If you're pressed for time, 30 minutes in the freezer works well too!) I always aim for rounder logs and end up with a more oval shape. It works!

Step 4

Heat the oven to 300°F.

Step 5

Cut the logs into 1/4-inch-thick slices with a sharp knife.

Step 6

Arrange the slices 2 inches apart on parchment-lined baking sheets.

Step 7

Bake the cookies on the top rack of the oven for 22-26 minutes.

Step 8

Transfer to wire racks to cool. Heat chocolate in a microwave for 1 minute, stir gently and continue heating in 15-second increments until smooth.

Step 9

Dip 3/4 of the cookie into chocolate. Set on wax paper and add holiday sprinkles. Do not remove until cool and set.
