Preheat the oven to 350 degrees. Line a baking sheet with parchment paper.
Beat together the butter and sugar until light and fluffy, about 3 minutes with a stand mixer. Beat in the eggs and vanilla until very well combined.
In a small bowl, combine the flour, baking powder, salt, and sprinkles. Gradually add the flour mixture to the butter mixture and mix until combined and the dough comes together.
Use a cookie scoop to drop balls of dough on the prepared baking sheet, about 1-inch apart. Bake for 11 minutes or until edges are turning golden and tops are just slightly underdone looking.
Cool for 10 minutes on the cookie sheet before transferring to a cooling rack to cool completely.
Notes
We use jimmies sprinkles, which melt into the cookies and leave little pops of color throughout. These can be made festive for any holiday by choosing specific colored sprinkles.
