PREPARE your favorite recipe for sugar cookies. Halve dough and tint with food colors.
PREHEAT oven following recipe. Roll out dough 1/8-inch thick between 2 lightly floured parchment paper sheets.
CUT OUT 48 cookies with a mitten cookie cutter. Place 12 cookies 1-inch apart on parchment-lined cookie sheets. Use mini cookie cutters to cut out decorations.
MELT mint baking chips in a microwave-safe bowl. Spread melted mint chips over cookies on the cookie sheets. Top each with another cookie cut-out. Place mini decorations on cookies. (To hold decorations in place, brush underside with egg whites beaten with a little water.) Repeat with remaining cut-out cookies.
