- ⅔ cup all purpose flour
- 2 eggs
- ⅓ cup butter {melted}
- 2 Tablespoons sour cream
- ¼ cup sprinkles {plus more for the top of the cookies}

Preheat oven to 350°.
Confetti Cookie
-
Combine cake mix, flour, eggs, melted butter, sour cream in a large bowl. Mix using a hand held {or stand} mixer until you have a thick dough. Add the sprinkles and mix in by hand until they are evenly distributed.
-
Using a 1/4 cup, measure out 11-12 cookies. Use your hands to press the cookie dough into a disc that is a thick round circle. Bake 6 cookies at a time. Place the cookie on a silicone mat {or parchment} lined baking sheet for 10-12 minutes or until set.
-
Remove cookies from the oven and allow them to cool completely on the baking sheet.
Cream Cheese Frosting
-
For the frosting, combine the softened cream cheese and butter in a large bowl with a hand held mixer until creamy and smooth. Add cake mix and powdered sugar and continue to mix until you have a pipeable consistency. Add enough milk to get the consistency you want.
Assembly
-
Add the frosting to a piping bag {or zipper bag} and cut a large triangle from the bottom. Pipe a circular motion starting on the outside and working your way to the middle. Sprinkle the top of each cookie with a few additional sprinkles. Store in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months.
