Step 1

Whisk the flour, baking powder, and salt together in a medium bowl. Set aside.

Step 2

In a large bowl using a hand mixer or a stand mixer fitted with a paddle attachment, beat the butter and granulated sugar together on medium-high speed until creamed, about 1 minute. Add the egg and vanilla extract and beat on high speed until combined, about 1 minute. Scrape down the sides and up the bottom of the bowl and beat again as needed to combine.

Step 3

Add the dry ingredients to the wet ingredients and mix on low until combined. Beat in 1/2 cup of sprinkles. Dough will be thick and sticky. Scoop large sections of dough (about 2 Tablespoons of dough each) and roll into balls. For extra sprinkle goodness, lightly dip the tops of the cookie dough balls in more sprinkles. Place dough balls onto a large plate or lined baking sheet.

Step 4

Cover and chill the cookie dough balls in the refrigerator for at least 2 hours (and up to 4 days).

Step 5

Preheat oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats. Set aside.

Step 6

Arrange chilled cookie dough balls 3 inches apart on the baking sheets. Bake for 11-12 minutes or until lightly browned on the sides. The centers will look very soft.

Step 7

Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Step 8

Cookies stay fresh covered at room temperature for up to 1 week.
