Preheat your oven to 350 degrees F.

In a bowl, whisk together the flour, baking powder, and salt. Set aside.

Cream together the butter and sugar until light and fluffy, about 2-3 minutes. Mix in the eggs, one at a time. Stir in the vanilla extract.

Add the dry ingredients to the wet mixture until just combined. Divide the dough in half into separate bowls.

Add 1 tablespoon of green sugar to one bowl and mix. Add 1 tablespoon of red sugar to the other bowl and mix.

Divide the remaining 1/2 cup sugar into two bowls. Mix 1 teaspoon green sugar into one bowl and 1 teaspoon red sugar into the other.

Spoon out 1-inch dough balls and roll in colored sugar. Place on the cookie sheet and slightly flatten each ball with your finger before baking.

Bake for 8-10 minutes. Remove from oven and place a peppermint kiss on each cookie, pressing slightly. Let cool completely before moving.
