Instructions:
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy.
Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract until combined.
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
Gradually incorporate the dry ingredient mixture into the wet ingredients, mixing until just combined.
Gently fold in the jimmie sprinkles, being careful not to over-mix the dough.
Chill the dough in the refrigerator for about 30 minutes to help with texture and shape retention.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, leaving 2-3 inches between each cookie.
Bake the cookies in the preheated oven for 10-13 minutes or until they're lightly golden around the edges but still slightly under-baked in the center.
Remove from the oven and let the cookies cool on the baking sheet for a few minutes before transferring them to a cooling rack.
For the best results, make sure not to over-bake the cookies to maintain their chewy texture. Experiment with different types of sprinkles for a unique twist, and consider adding a pinch of cornstarch to the dough for an even softer cookie.
Enjoy your funfetti cookies fresh out of the oven or store them in an airtight container to keep them soft and delicious!
