Soft cake mix cookies topped with vanilla frosting and rainbow nonpareils. Inspired by the viral dot cake trend, these colorful cookies combine birthday cake flavors with a fun sprinkle-covered finish.
Preheat the oven to 350°F. Line two baking sheets with parchment paper.
In a large bowl, mix the cake mix, oil, and eggs until a thick dough forms.
Use a 2-tablespoon cookie scoop to portion the dough onto the prepared baking sheets, leaving about 2 inches between each cookie.
Bake for 9-11 minutes, or until the edges are set.
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Beat the butter until smooth. Add the powdered sugar, vanilla extract, salt, and 1 tablespoon of milk. Mix until smooth, adding additional milk as needed to reach a spreadable consistency.
Spread frosting over the cooled cookies.
Pour the nonpareils into a wide, shallow bowl or small rimmed plate. Dip each frosted cookie into the sprinkles until the frosting is evenly coated.
Notes
Store the cookies in an airtight container for up to 3 days.
Freeze the unfrosted cookies in a freezer-safe container for up to 3 months. Thaw at room temperature, then frost and decorate before serving.
