325* oven.
Line your baking sheet with parchment paper or a silicone baking mat and set aside. Don't use a spray grease or your cookies may spread.
Whisk together your dry ingredients.
In the bowl of a stand mixer, cream the Butter and Sugar until light and fluffy, roughly two minutes.
Add the Egg, Food Coloring, and Vanilla Extract. Beat until combined (roughly one minute), scraping the bottom of the bowl and the sides as required.
Add in the flour mixture. DO NOT OVERMIX. Stop mixing when you see a few streaks of flour and mix the rest by hand.
Scoop out 1 teaspoon, either forming balls with your hands (which is stupid time consuming) or save yourself the hassle and get a cookie dough scoop. Set the balls 2" apart.
Lightly press your index finger's knuckle into the soft cookie dough ball. Don't press all the way down. All you are doing is creating a shallow well for frosting.
Bake from 9 to 12 minutes or until you can smell the cookies, they look "set," and the bottoms are lightly browned.
Set cookies to cool on a wire rack away from your heat source (if you do not use a wire rack, your cookies will keep baking, and will take longer to cool down). After 5 minutes, lightly press your knuckle into the cookies again. DO NOT do like I do and decide to press down shortly after you remove the cookies from the oven. It's HOT. Oops.
Cool completely before you spoon in or pipe on the frosting.
