Ingredients
Scale
For the Cupcakes:
- 1 ½ cups all-purpose flour
- 1 cup granulated sugar
- ½ cup unsalted butter, softened
- 3 large eggs
- ½ cup buttermilk
- 2 tablespoons poppy seeds
- 1 tablespoon baking powder
- 1 teaspoon vanilla extract
- Zest of 1 lemon
- Juice of 1 lemon
- ¼ teaspoon salt
For the Blackberry Frosting:
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- ½ cup fresh blackberries
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners to prevent sticking and ensure easy cleanup.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, poppy seeds, and salt thoroughly to evenly distribute the leavening and seeds.
- Cream Butter and Sugar: In a large mixing bowl, beat the softened unsalted butter and granulated sugar together using a mixer until the mixture becomes light, fluffy, and pale in color. This will help create a tender crumb in the cupcakes.
- Add Eggs: Incorporate the eggs one at a time into the batter, beating well after each addition to ensure proper emulsification and volume.
- Incorporate Buttermilk and Lemon Flavor: Mix in the buttermilk, lemon zest, and lemon juice until the batter is smooth and the flavors are well combined.
- Combine Wet and Dry Ingredients: Gradually add the dry flour mixture into the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the cupcakes light and tender.
- Fill Cupcake Liners: Spoon the batter evenly into the cupcake liners, filling each about two-thirds full to allow space for rising during baking.
- Bake: Place the cupcake tin in the preheated oven and bake for 15-20 minutes. Check doneness by inserting a toothpick into the center of a cupcake; it should come out clean.
- Cool: Remove the cupcakes from the oven and let them cool in the tin for 5 minutes before transferring them to a wire rack to cool completely, which is crucial for frosting application.
- Prepare Blackberry Frosting: Puree fresh blackberries in a blender or food processor and strain the puree to remove seeds if desired for a silky texture. Beat softened butter in a mixing bowl until creamy, then gradually add powdered sugar, mixing until smooth and fluffy. Add the blackberry puree, lemon juice, vanilla extract, and pinch of salt. Beat until the frosting is well combined, smooth, and airy.
- Frost the Cupcakes: Once the cupcakes have completely cooled, generously frost them using a piping bag or spatula with the prepared blackberry frosting, creating an attractive and flavorful topping.
Notes
- Ensure cupcakes are completely cool before frosting to prevent frosting from melting.
- Straining the blackberry puree helps achieve a smooth frosting without seeds.
- You can substitute lemon buttermilk by adding ½ tablespoon lemon juice to regular milk and letting it sit for 5 minutes.
- Store cupcakes in an airtight container in the refrigerator if not served immediately; bring to room temperature before serving for best flavor.
- Poppy seeds add delightful texture but can be omitted if you prefer a seedless experience.
