Step 1

In a large mixing bowl, beat butter with both sugars. Add in eggs and vanilla extract, beat until fully combined, scraping down the sides of the bowl as needed.

Step 2

Add in flour, baking powder, and salt. Mix just until combined. Add sprinkles, do not overmix.

Step 3

Lay three long pieces of plastic wrap (or the Press and Seal version) on your counter (if using press and seal, make the sticky side down). Divide the dough into three portions, dropping it into the center of each piece of plastic wrap.

Step 4

Using your hands, make dough into a ball, then form into a log. Roll up into the plastic wrap and keep pressing dough until log is about 2 inches in diameter throughout. Repeat for each portion of dough.

Step 5

Place cookie dough in refrigerator for at least 4 hours (or up to 3 days).

Step 6

When ready to bake, preheat oven to 375 degrees F. Line a cookie sheet with parchment paper and set aside.

Step 7

Remove plastic wrap from cookie dough and slice the dough into 1/4-inch slices. Place on prepared baking sheet about 2-inches apart. Bake for 9-11 minutes.

Step 8

Allow to cool 5 minutes on cookie sheet, then remove and cool completely on a wire rack.
