Preheat oven to 300°F, and line a cookie sheet with a piece of parchment.
In a medium mixing bowl, whisk together all-purpose flour, cornstarch and salt and put aside.
Using a stand mixer with the paddle attachment, beat the softened butter, powdered sugar, and vanilla together until light and fluffy (about 3-5 minutes). Scrape down the sides and bottom of the bowl as needed.
Gradually add in the flour mixture, about ½ cup at a time, mixing until fully incorporated.
Using a 1 tablespoon cookie scoop, place dough about 1 inch apart on a baking sheet.
Lightly dip a fork in flour and tap any excess off. Flatten the cookies about 1/3 of the way down. Add sprinkles and bake for 12-13 minutes.
Allow them to cool for at least 15 minutes on the cookie sheet before transferring to a wire rack.
