In a large bowl, whisk together flour, baking powder, baking soda, and salt, then set to the side.
Using an electric mixer and a separate large bowl, beat butter until smooth. Pour in the sugar and cream for 1 minute until light and fluffy.
Add eggs and vanilla extract, then beat until combined.
Gently fold in the flour mixture and combine with a wooden spoon or plastic spatula. Next, gently fold in the sprinkles.
Use a medium-sized cookie scoop to scoop the cookie dough onto a non-stick baking tray, spacing 2 to 3 inches apart.
Bake for 10-12 minutes or until the edges are set and the center of the cookies looks slightly underbaked.
Leave the cookies on the baking tray for 5 minutes before removing them to cool completely on a cooling rack.
Notes
If you're a fan of taller and puffier cookies, leave the cookie dough to cool for at least 30 minutes but ideally 1 hour. It stops the cookies from spreading out as much while baking.
It's best to portion out the cookie dough before chilling. Once chilled, the butter inside the cookie dough will become firm. This will make the cookie dough much tougher to portion.
The sprinkled sugar cookie dough can be wrapped and chilled in the fridge for up to 2 days before baking. Once baked, the sprinkle sugar cookies can be stored in an airtight container at room temperature for up to a week.
