Preheat the oven to 350℉. Line or spray a baking pan and set aside. Add 1/4 cup sprinkles to a bowl for decoration and set aside.
In the bowl of a stand mixer or large mixing bowl, add the butter and sugar. Beat together on medium speed for 3-4 minutes until creamed.
Add the egg and mix until incorporated. Add the vanilla and mix until incorporated.
Add the flour, baking powder, salt and sprinkles and mix until fully incorporated.
Scoop 2 tbsp size cookies. Roll them into a ball and then dip the top into the sprinkles we set aside earlier. Set them on the pan at least 2 inches apart and bake for 9-11 minutes, or until the edges just start to feel firm.
Transfer the cookies to a wire rack to fully cool. Store in an airtight container for up to 3 days and enjoy!
