1-2tablespoonsheavy creamas needed to thin frosting
Instructions
Preheat oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners and set out a few extra liners for the additional batter.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
In a large bowl, whisk melted butter and granulated sugar until well combined. Add eggs one at a time, whisking well after each. Whisk in sour cream, milk, vanilla, and lemon zest until smooth.
Pour dry ingredients into wet and whisk or fold gently just until no streaks of flour remain. Do not overmix.
Toss fresh blueberries with 1 tablespoon flour in a small bowl, then gently fold them into the batter with a rubber spatula, being careful not to crush them.
Divide batter evenly among liners, filling each about two-thirds full. Bake for 18-20 minutes, until a toothpick comes out clean. Cool in pan 5 minutes, then transfer to a wire rack to cool completely.
Beat softened cream cheese and butter together until smooth and creamy, about 2 minutes. Gradually add powdered sugar, mixing on low then increasing to medium. Add vanilla and salt, beat until fluffy. Add heavy cream 1 tablespoon at a time if frosting is too thick.
Transfer frosting to a piping bag and pipe a swirl on top of each completely cooled cupcake. Garnish with fresh blueberries.
Notes
Use fresh blueberries instead of frozen when possible, as frozen berries release excess moisture and can weigh down the batter.
Always toss blueberries in flour before folding them in to keep them suspended throughout the batter instead of sinking.
Do not overmix the batter once flour is added — a few gentle folds is all it takes for tender cupcakes.
Make sure butter and cream cheese are fully softened before making the frosting to avoid lumps.
Let cupcakes cool completely before frosting, or the frosting will melt right off.
For a lemon blueberry variation, add extra lemon zest to the batter and a squeeze of lemon juice to the frosting.
Store frosted cupcakes in an airtight container in the refrigerator for up to 4 days.
Unfrosted cupcakes can be frozen for up to 2 months — thaw at room temperature before frosting.
Bring refrigerated cupcakes to room temperature for about 20 minutes before serving for best texture and flavor.
For mini cupcakes, use a mini muffin pan and reduce baking time to about 12 minutes.
