Preparation
- Preheat the oven to 350°F and line two cookie sheets with parchment paper or silicone baking mats.
- In a standing mixer, combine the cake mix, egg, and softened butter. Beat until a soft dough forms.
- Fold in 1 cup of sprinkles until evenly distributed through the dough.
Assembling the Cookies
- Use a small cookie scoop to portion the dough and roll each portion in remaining 2 cups of sprinkles.
- Place on prepared sheets spaced about 1 to 1.5 inches apart.
- Bake for 10–12 minutes until tops look set. Remove and cool completely.
Making the Frosting
- Beat the softened butter with powdered sugar, vanilla, heavy whipping cream, and pink gel food coloring until creamy.
- Scoop frosting into a piping bag with a star tip and pair cookies into sandwiches.
