Best Sugar Cookie Recipe
YIELD: 3 dozen cookies
PREP TIME: 30 minutes
COOK TIME: 6-8 minutes
TOTAL TIME: 38 minutes
Soft cut out sugar cookie recipe that keeps its shape and dough does not need to be chilled before baking- perfect edges every time!

INGREDIENTS:
1 Cup unsalted butter
1 Cup granulated white sugar
1 teaspoon vanilla extract
1/2 teaspoon almond extract
1 egg
2 teaspoons baking powder
1/2 teaspoon salt
4 cups all purpose flour
DIRECTIONS:
Preheat oven to 350° F.
In the bowl of your mixer cream butter and sugar until smooth, at least 3 minutes
Beat in extracts and egg.
In a separate bowl combine baking powder and salt with flour and add a little at a time to the wet ingredients. The dough will be very stiff. If it becomes too stiff for your mixer turn out the dough onto a countertop surface. Wet your hands and finish off kneading the dough by hand.
DO NOT CHILL THE DOUGH. Divide into workable batches, roll out onto a floured surface and cut. You want these cookies to be on the thicker side (closer to 1/4 inch rather than 1/8).
Bake at 350 for 6-8 minutes. Let cool on the cookie sheet until firm enough to transfer to a cooling rack.

For the icing:
1 cup powdered sugar
2 TbSP corn syrup
1 TBSP milk
1/4 tsp almond extract
And gel colors of your liking
