Preheat oven to 350°F. In a medium bowl whisk together flour, baking powder, baking soda, and salt. Set aside. In a large bowl beat the butter, granulated sugar, and brown sugar until light and fluffy.

Add the egg and vanilla. Mix until combined. Slowly mix in the dry ingredients until just combined.

Fold in sprinkles.

Scoop cookie dough and shape into balls on baking sheet. Press down on each cookie dough to flatten them out a bit. Bake for about 9-11 minutes. Let the cookies cool before frosting. (I let cool 5 min on baking sheet before transferring to cooling rack).

In a bowl beat the cream cheese, butter, vanilla, and salt until smooth and combined. Add the powdered sugar 1/3 at a time and mix until combined.

You can use a piping bag or frosting tool and frost cookies. Add as many sprinkles as you would like!
