Ingredients

Scale

Cupcakes:

  • 1 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup whole milk
  • 1/3 cup blackberry puree (from fresh or frozen blackberries)

Blackberry Swirl Frosting:

  • 1/2 cup unsalted butter, softened
  • 2 1/2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 3–4 tablespoons blackberry puree (strained to remove seeds)
  • 2–3 tablespoons heavy cream or milk

Garnish:

  • Fresh blackberries
  • Mint leaves (optional)

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners. Using parchment paper liners is recommended to prevent sticking and keep the shape of the cupcakes.
  2. Mix Dry Ingredients: In a medium bowl, whisk the all-purpose flour, baking powder, and salt together. Set this mixture aside.
  3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar on medium speed until the mixture becomes light and fluffy, about 3-4 minutes. This is essential for a tender cupcake texture.
  4. Add Eggs and Vanilla: Beat in the eggs one at a time to the creamed butter mixture, then add the vanilla extract and mix until well incorporated.
  5. Combine Dry Ingredients and Milk: Gradually add the dry ingredients to the butter mixture, alternating with the whole milk. Start and end with dry ingredients. Mix just until combined to avoid overmixing, which can make cupcakes tough.
  6. Create Blackberry Swirl Batter: Divide the batter evenly into two bowls. Gently fold the blackberry puree into one bowl to color and flavor that portion. Then, spoon alternating dollops of vanilla and blackberry batter into each cupcake liner, filling them roughly two-thirds full. Use a toothpick to lightly swirl the two batters for a marbled effect.
  7. Bake the Cupcakes: Place the muffin tin in the preheated oven and bake for 18-20 minutes. Check doneness by inserting a toothpick into the center; it should come out clean. Rotate the pan halfway through baking to ensure even cooking.
  8. Cool Completely: Allow cupcakes to cool in the pan for 5 minutes before transferring them to a wire rack to cool fully before frosting.
  9. Prepare Blackberry Swirl Frosting: Beat the softened butter in a large bowl until creamy. Gradually add the powdered sugar one cup at a time, alternating with heavy cream, beating until smooth and fluffy. Divide the frosting into two bowls: stir vanilla extract into one and the strained blackberry puree into the other. Fill a piping bag with the two frostings side by side using a star tip to achieve the swirl effect.
  10. Frost the Cupcakes: Once the cupcakes are completely cooled, pipe the blackberry swirl frosting onto each cupcake. Start piping from the center and swirl outward with steady pressure to create a beautiful marbled design.
  11. Garnish and Serve: Top each cupcake with a fresh blackberry and optionally add a small mint leaf for a pop of color and freshness.

Notes

  • Make sure the butter is softened for easier mixing and a smoother batter and frosting.
  • To get a seed-free frosting, strain the blackberry puree before mixing it in.
  • Do not overmix the batter to preserve the cupcakes’ light and tender crumb.
  • Use parchment cupcake liners to prevent sticking and maintain the perfect shape.
  • Rotate the baking pan halfway through baking for even cupcake rise and color.
  • For a dairy-free version, substitute butter and milk with plant-based alternatives but expect slight texture changes.
