Ingredients

Scale
  • 1 ½ cups (190g) all-purpose flour, sifted
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup (113g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 2 large eggs, room temperature
  • ½ cup (120ml) whole milk, room temperature
  • 1 teaspoon pure vanilla extract
  • 1015 drops pink food coloring (gel or liquid)
  • 1015 drops blue food coloring (gel or liquid)
  • 4 oz (115g) cream cheese, softened
  • ½ cup (60g) powdered sugar, sifted
  • ½ teaspoon vanilla extract (for filling)
  • 2 tablespoons (30ml) heavy cream
  • Optional Frosting:
  • ½ cup (113g) butter, softened
  • 2 cups (240g) powdered sugar
  • 2 tablespoons (30ml) milk
  • 1 teaspoon vanilla extract
  • Pink and blue food coloring as needed

Instructions

  1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
  2. In a medium bowl, whisk together flour, baking powder, and salt; set aside.
  3. In a large bowl, beat softened butter and sugar until fluffy and pale, about 3-4 minutes.
  4. Beat in eggs one at a time, then stir in vanilla extract.
  5. Add dry ingredients in three parts, alternating with milk, beginning and ending with flour mixture; mix gently after each addition.
  6. Divide batter into two bowls; add pink food coloring to one and blue to the other, stirring gently.
  7. Spoon alternating dollops of pink and blue batter into cupcake liners; use a toothpick to create soft swirls without overmixing.
  8. Bake for 18-20 minutes or until a toothpick inserted comes out clean with a few moist crumbs.
  9. Cool cupcakes completely on a wire rack.
  10. Beat cream cheese, powdered sugar, vanilla extract, and heavy cream until smooth and fluffy; chill if needed.
  11. Core the center of each cupcake using a knife or cupcake corer.
  12. Pipe or spoon the cream cheese filling into the holes and press the removed cake pieces back on top to seal.
  13. Optional: Prepare buttercream frosting by whipping butter, powdered sugar, milk, and vanilla; tint with pink and blue food coloring and swirl on top using a piping bag with a star tip.

Notes

If batter is too thick, add a tablespoon of milk to loosen. Use a light hand when swirling colors to avoid muddy patterns. Chill filling if too soft to pipe. Cool cupcakes completely before coring and filling to prevent crumbling. Use an ice cream scoop for uniform cupcake size. Store cupcakes in an airtight container in the fridge for up to 3 days or freeze individually for up to 2 months.
