Ingredients

Scale
  • 1 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1/2 cup sour cream
  • 1/2 cup whole milk
  • Gel food coloring (red, orange, yellow, green, blue, purple)
  • 1 cup unsalted butter, softened (for frosting)
  • 3 cups powdered sugar
  • 23 tablespoons whole milk (for frosting)
  • 1 teaspoon vanilla extract (for frosting)
  • Pinch of salt (for frosting)
  • Mini rainbow candies or rainbow sour belts
  • Edible gold coins, gold sugar pearls, or gold sprinkles
  • Edible glitter or shimmer dust (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners; lightly spray silicone liners if using.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, cream butter and sugar with an electric mixer until light and fluffy (2-3 minutes).
  4. Beat in eggs one at a time, then add vanilla extract. Mix well and scrape down the sides.
  5. Mix in half the dry ingredients, then add sour cream and milk. Finish with remaining dry ingredients, mixing just until smooth.
  6. Divide batter evenly into six bowls. Add gel food coloring to each bowl for red, orange, yellow, green, blue, and purple. Mix gently.
  7. Layer colored batter into cupcake liners in rainbow order, about 1 teaspoon of each color per layer. Smooth tops gently.
  8. Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean. Cool in pan for 5 minutes, then transfer to wire rack.
  9. For frosting: Beat butter until creamy. Gradually add powdered sugar, mixing on low. Add milk, vanilla, and salt. Beat until light and fluffy (2-3 minutes). Adjust consistency with milk as needed.
  10. Pipe or spread frosting on cooled cupcakes. Decorate with rainbow candies, gold coins or sprinkles, and edible glitter if desired.
  11. Serve at room temperature. Store extras in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days.

Notes

Use gel food coloring for vibrant colors. Don’t overmix the batter to keep cupcakes tender. Decorate just before serving for the freshest look. For gluten-free or vegan adaptations, substitute flour, butter, milk, and eggs as needed. Store decorated cupcakes at room temperature for up to 2 days, or refrigerate for up to 5 days. Freeze unfrosted cupcakes for longer storage.
