Ingredients

Scale

  • 1 cup granulated sugar
  • 1/2 cup brown sugar, packed
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 cup rainbow sprinkles
  • 1/2 cup unsalted butter, softened (for frosting)
  • 3 cups powdered sugar, sifted
  • 23 tbsp milk (dairy-free milk optional)
  • 1 tsp vanilla extract (for frosting)
  • Gel food coloring in red, orange, yellow, green, blue, and purple

Instructions

  1. Preheat oven to 350°F (175°C). Grease muffin tin or line with silicone liners.
  2. Cream 1 cup softened butter, granulated sugar, and brown sugar together until light and fluffy, about 3-4 minutes.
  3. Beat in eggs one at a time, then add vanilla extract until smooth and glossy.
  4. In a separate bowl, whisk together flour, baking soda, and salt.
  5. Gradually add dry ingredients to wet mixture on low speed until just combined.
  6. Fold in rainbow sprinkles gently.
  7. Scoop about 2 tablespoons of dough into each muffin cup and press gently to form shallow cups.
  8. Bake for 12-14 minutes until edges are golden and centers set but soft.
  9. Cool in pan for 10 minutes, then transfer to cooling rack to cool completely.
  10. Beat 1/2 cup softened butter for frosting until creamy.
  11. Gradually add powdered sugar, alternating with milk and vanilla, until smooth and spreadable.
  12. Divide frosting into six bowls and tint each with a different gel food color.
  13. Fill piping bags with each color and pipe rainbow swirls inside each cookie cup starting with purple and layering through red.
  14. Top with extra rainbow sprinkles.
  15. Serve immediately or store as directed.

Notes

Use room temperature eggs for smooth batter. Do not overmix dough to avoid tough cookies. Gel food coloring provides vibrant hues without thinning frosting. Cookie cups are best served same day but can be stored at room temperature for 2 days or refrigerated for up to a week. Freeze unfrosted cookie cups for up to 3 months. Reheat in a low oven (300°F) for 5 minutes to refresh texture.
