Preheat oven to 300° F. Line two baking sheets with parchment paper and set aside.
In a medium bowl, beat together first 5 ingredients until smooth. Slowly add in flour and mix thoroughly.
On a lightly floured surface, roll dough until ¼-inch thick. Use a 2-inch cookie cutter or cut into squares and place 1-2 inches apart on baking sheets.
Bake 19-22 minutes or until center of cookie is firm. Cool completely on wire rack.
Melt CANDIQUIK according to package directions and mix in coffee grounds.
Dip ½ of each cookie (or drizzle for a different look!) in CANDIQUIK and allow it to set on wax or parchment paper.
