Ingredients

Scale
  • 2 ½ cups (312 g) all-purpose flour
  • 1 tsp (4 g) baking powder
  • ½ tsp (3 g) salt
  • 1 cup (227 g) unsalted butter, softened (for cookie cups)
  • ¾ cup (150 g) granulated sugar
  • ¼ cup packed (50 g) brown sugar
  • 1 ½ tsp (7 ml) vanilla extract
  • 2 large eggs, room temperature
  • 1 cup (227 g) unsalted butter, softened (for frosting)
  • 4 cups (480 g) powdered sugar, sifted
  • 1 tsp (5 ml) vanilla extract
  • 23 tbsp (3045 ml) whole milk
  • Gel food coloring (red, orange, yellow, green, blue, purple)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 12-cup muffin tin or line with silicone liners.
  2. In a medium bowl, whisk together all-purpose flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened unsalted butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy (about 3-4 minutes).
  4. Beat in eggs one at a time, then stir in vanilla extract until fully combined.
  5. Gradually add the flour mixture to the butter mixture, mixing on low until just combined.
  6. Divide the dough evenly among muffin cups (about 2 tbsp per cup). Press dough into bottom and up sides to form shallow bowls.
  7. Bake for 12-15 minutes until edges are lightly golden and centers set but still soft. Cool in the tin for 10 minutes, then transfer to a wire rack to cool completely.
  8. For the frosting, beat softened unsalted butter until creamy. Gradually add powdered sugar, mixing on low speed.
  9. Add vanilla extract and whole milk to reach a spreadable but firm consistency.
  10. Divide frosting into 6 small bowls and tint each with a different gel food coloring.
  11. Fill piping bags with each colored frosting. For swirl effect, spoon all colors side-by-side into a larger piping bag without a tip.
  12. Pipe rainbow swirls starting at the edge of each cookie cup moving toward the center, layering colors gently.
  13. Refrigerate cookie cups for at least 30 minutes to let frosting set before serving.

Notes

Use gel food coloring to keep frosting vibrant without thinning. Room temperature butter is key for both dough and frosting. Chill frosting if it becomes too soft while piping. Let cookie cups cool completely before frosting to prevent melting. Store frosted cups refrigerated and bring to room temperature before serving for best texture.
