Lemon Poppy Seed Cupcakes with Blackberry Frosting πŸ‹πŸ’œ

Prep Time: 20 minutes | Cooking Time: 20 minutes | Total Time: 40 minutes | Kcal: 280 kcal | Servings: 12 cupcakes


  • 1 and 1/2 cups all-purpose flour
  • 1 tablespoon poppy seeds
  • 1 teaspoon 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 vanilla extract
  • 1/2 cup sour cream
  • Zest of 2 lemons
  • 2 tablespoons fresh lemon juice

For the Blackberry Frosting:

  • 1/2 cup unsalted butter, softened
  • 3 cups powdered sugar
  • 1/4 cup fresh blackberries, mashed
  • 1-2 tablespoons milk or cream, if needed


  • Preheat the oven to 350Β°F (175Β°C). Line a 12-cup muffin tin with cupcake liners.
  • In a medium bowl, whisk together the flour, poppy seeds, baking powder, baking soda, and salt.
  • In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
  • Beat in the eggs, one at a time, followed by the vanilla extract.
  • Mix in the sour cream, lemon zest, and lemon juice until well combined.
  • Gradually add the dry ingredients to the wet ingredients, mixing until just incorporated.
  • Divide the batter evenly among the prepared cupcake liners, filling each about 2/3 full.
  • Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
  • Remove from the oven and allow the cupcakes to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

For the Blackberry Frosting:

  • In a large mixing bowl, beat the softened butter until creamy.
  • Gradually add the powdered sugar, mixing until smooth and fluffy.
  • Fold in the mashed blackberries until well combined. If the frosting is too thick, add milk or cream, 1 tablespoon at a time, until desired consistency is reached.
  • Once the cupcakes are completely cooled, frost them with the blackberry frosting.
