Best sugar cookie recipe

1 cup butter
1 cup white sugar
1 teaspoon vanilla extract
1 egg
2 teaspoons baking powder
1/2 teaspoon salt
3 cups flour

Preheat oven to 350 degrees. In the bowl of your mixer, cream butter and sugar until smooth, at least 3 minutes. Beat in vanilla and egg. In a separate bowl, combine baking powder and salt with flour. Add dry mixture to wet mixture slowly. The dough will be very stiff. If it becomes too stiff for your mixer, turn the dough out onto a countertop surface and finish mixing by hand. Do not chill the dough. Divide into workable batches and roll out onto a floured surface and cut. You want these cookies to be on the thicker size, closer to 1/4-inch. Bake at 350 for 8-9 minutes. Let cool on the cookie sheet until firm enough to transfer to a cooling rack. Top with your favorite frosting and sprinkles.
