This is a fun holiday recipe (especially Christmas or St. Patrick's Day) originally from the cookbook "Honest Pretzels." I made a few small changes and additions to the recipe. We love them! They are very pepperminty.
Preheat oven to 350 degrees. Line a baking sheet with parchment paper or spray lightly with cooking spray.
Mix melted butter, sugar, peppermint extract and vanilla extract. Mix in beaten egg and milk and stir well.
In a separate bowl stir together flour, baking powder, salt and jar of green sugar crystals.
Add flour mixture to butter mixture and stir gently until well mixed. Using small cookie scoop or hands, form small balls (about 1 inch). Place on prepared baking tray (they can be close, but not touching).
Bake for 10-12 minutes. If desired, take out a few minutes before the baking time is up, decorate the tops with kisses or chips and bake for a couple minutes more.
Cool on a wire rack, then enjoy! These cookies taste best after cooling to room temperature.
