Ingredients
Method
- Preheat the oven to 350°F (177°C) and line a 12-cup muffin pan with liners. If making 15 cupcakes, prepare a second pan with 3 liners or bake in batches.
- In a large bowl, whisk together the flour, baking powder, baking soda, and salt until evenly combined.
- In a medium bowl, whisk melted butter and sugar together until slightly blended. Add egg whites, sour cream, milk, and vanilla extract, whisking until smooth.
- Pour the wet ingredients into the dry ingredients and whisk gently until just combined. Batter should be creamy with small lumps remaining. Carefully fold in the blueberries with a spatula.
- Spoon the batter into the cupcake liners, filling each about two-thirds full to prevent overflow.
- Bake for 20–22 minutes, or until a toothpick inserted in the center comes out clean.
- Allow cupcakes to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely, about 30 minutes.
- For the frosting, whip the heavy cream in a large bowl using a hand or stand mixer on medium-high speed until stiff peaks form, about 3–4 minutes.
- In the same bowl, beat the cream cheese until smooth and creamy. Add confectioners’ sugar, lemon zest, lemon juice, and vanilla extract, mixing until well combined.
- Gently fold the whipped cream into the cream cheese mixture until just combined, careful not to overmix.
- Frost the completely cooled cupcakes using a piping bag or spatula. Optionally garnish with fresh blueberries and mint leaves.
- Serve immediately or store in the refrigerator for up to 5 days.
