Ingredients

Scale

For the Cupcakes:

  • 1 ½ cups self-rising flour
  • ½ cup unsalted butter, softened
  • ¾ cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • ½ cup whole milk
  • 1 tbsp orange juice + zest of ½ orange
  • 1 tbsp lime juice + zest of ½ lime
  • 1 tbsp raspberry puree
  • Food coloring: orange, pink, and green

For the Citrus Buttercream Swirl:

  • 1 cup unsalted butter, softened
  • 3 cups powdered sugar
  • 1 tbsp orange juice
  • 1 tbsp lime juice
  • 1 tsp vanilla extract
  • 1 tbsp heavy cream (if needed for consistency)
  • Food coloring: orange, pink, and green

Instructions

  1. Preheat & Prepare: Preheat the oven to 350℉ (175℃). Line a 12-cup muffin tin with cupcake liners to prepare for baking.
  2. Make the Batter: In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy. Add eggs one at a time, blending thoroughly after each addition. Stir in the vanilla extract. Gradually fold in the self-rising flour, alternating with the whole milk, mixing gently and just until combined to avoid overmixing.
  3. Divide & Color the Batter: Split the batter evenly into three separate bowls. In the first bowl, mix in the orange juice, orange zest, and a drop of orange food coloring. In the second bowl, combine lime juice, lime zest, and green food coloring. In the third bowl, fold in raspberry puree and a drop of pink food coloring, creating three distinctly colored and flavored batters.
  4. Assemble & Bake: Spoon small amounts of each colored batter alternately into the cupcake liners, layering them and using a toothpick to gently swirl the colors for a marbled effect. Bake the cupcakes in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and allow cupcakes to cool completely.
  5. Make the Citrus Buttercream Swirl: Beat the softened butter until creamy using a mixer. Gradually add powdered sugar, then mix in orange juice, lime juice, and vanilla extract until smooth. If the frosting is too thick, add the heavy cream a little at a time until it reaches a fluffy, pipeable consistency. Divide the frosting into three portions and tint each with orange, pink, and green food coloring respectively.
  6. Frost & Decorate: Spoon each colored buttercream into separate piping bags. Nest the three piping bags inside one larger piping bag fitted with your desired decorative tip. Pipe the multi-colored citrus buttercream onto the cooled cupcakes, creating a beautiful and vibrant swirl effect that complements the sherbet-inspired cupcake flavors.

Notes

  • Use good quality fresh juices and zest for the best citrus flavor.
  • Make sure cupcakes are fully cooled before frosting to prevent the buttercream from melting.
  • You can substitute raspberry puree with fresh or frozen raspberries blended and strained.
  • Adjust food coloring quantity to achieve desired vibrancy.
  • This recipe works well with a hand mixer or stand mixer for thorough blending.
  • Store cupcakes in an airtight container at room temperature for up to 2 days or refrigerate for longer freshness.
