Preheat oven to 350°F and line a baking sheet with parchment paper. Spray with nonstick spray and set aside.
In a large bowl, combine the eggs and vegetable oil. Stir in the cake mix and baking powder until well combined.
2 large eggs, ⅓ cup vegetable oil, 16 ounces confetti cake mix, 1 teaspoon baking powder
Fold in the confetti sprinkles.
¼ cup rainbow sprinkles
Use a 2-tablespoon-sized scoop to make large cookies. Space the cookies out so they don’t touch as they bake.
Bake for 8-9 minutes and remove. Cool on the pan for 5 minutes, then place on a cooling rack until completely cooled.
While the cookies cool, make the icing. In a large bowl, using a hand mixer, beat the butter and cream cheese together, then beat in the powdered sugar and vanilla. Mix in food coloring, if desired.
6 tablespoons unsalted butter, 4 ounces cream cheese, 1 cup powdered sugar, 1 teaspoon pure vanilla extract, Pink food coloring
Place the icing in a Ziplock bag and snip off a little bit of the corner.
Start at the center of the cookie and go in a circle out. Add sprinkles to the top of the cookies.
¼ cup rainbow sprinkles
