Begin by heating your oven to 300°F and lining baking sheets with parchment paper. Then whip the butter and sugar together until very light and fluffy. In a separate bowl, whisk the dry ingredients together. Then slowly add the dry ingredients to the butter mixture and mix for an additional 5-6 minutes on medium-high speed. This is what creates the light and fluffy dough.
Then scoop ¾-inch balls of dough and place on the cookie sheets. Next, use a fork to press the cookies down in the middle. Then place sprinkles or colored sugar on top.
Bake the cookies for 22-25 minutes. The cookies should not brown-just set. Allow the cookies to cool on the baking sheet for a few minutes before moving to a wire rack. Serve and enjoy!
