Soft and Colorful Unicorn Cookies with Rainbow Sprinkles (Print version)

Soft sugar cookies swirled with pastel gel colors and rainbow sprinkles for bright, chewy party cookies.

# Ingredients:

For the cookie dough

01 - 1 cup (226 g) unsalted butter, softened
02 - 1 1/2 cups (300 g) granulated sugar
03 - 2 large eggs, room temperature
04 - 2 teaspoons vanilla extract
05 - 3 1/4 cups (390 g) all-purpose flour
06 - 1 tablespoon cornstarch
07 - 1/2 teaspoon baking soda
08 - 1/2 teaspoon cream of tartar
09 - 1/2 teaspoon fine salt
10 - 2/3 cup rainbow jimmie sprinkles

For coloring and finishing

11 - Pink gel food coloring
12 - Blue gel food coloring
13 - Purple gel food coloring
14 - 1/4 cup extra rainbow sprinkles or coarse sugar, for rolling

# Instructions:

01 - Heat the oven to 350 F. Line two baking sheets with parchment paper.
02 - Beat the softened butter and granulated sugar on medium speed for about 3 minutes, until pale and fluffy.
03 - Beat in the eggs one at a time. Mix in the vanilla until smooth, scraping the bowl as needed.
04 - Whisk the flour, cornstarch, baking soda, cream of tartar, and salt in a separate bowl. Add to the butter mixture on low speed until just combined.
05 - Fold in the rainbow jimmies gently so they are evenly scattered without breaking down.
06 - Divide the dough into four portions. Leave one plain, then tint the others pink, blue, and purple. Place chunks of each color in one bowl and fold a few times to create a marbled look.
07 - Scoop 2 tablespoon dough balls and roll the tops in extra sprinkles or coarse sugar. Space them 2 inches apart on the prepared baking sheets.
08 - Bake for 10-12 minutes, until the edges are set and the centers still look soft. Cool on the baking sheet for 5 minutes, then transfer to a wire rack.

# Good to know:

01 - Makes about 20 medium cookies.
02 - Use gel food coloring for the brightest dough.
03 - Store airtight at room temperature for 4-5 days.
