Method
Preparation
- Preheat your oven to 350°F (175°C) and line a 12-count cupcake tin with paper liners.
- In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt.
- In a large bowl, combine the granulated sugar and lemon zest and rub them together with your fingers.
- Add vegetable oil and melted butter, whisking until combined. Then, add eggs, lemon juice, vanilla extract, and sour cream.
- Fold the dry ingredients into the wet mixture until just combined.
- Divide the batter among the cupcake liners, filling them 3/4 full.
- Bake for 15-20 minutes, checking with a skewer for doneness. Cool in the tin for 5 minutes, then transfer to a wire rack.
Frosting
- In a medium saucepan, combine blueberries and lemon juice over medium heat and cook until blueberries burst, about 5-8 minutes.
- Set the blueberry mixture aside to cool completely.
- In a large bowl, whip cream cheese and butter until smooth.
- Gradually add powdered sugar and mix until well incorporated.
- Stir in the cooled blueberry sauce until smooth. Chill for 30-60 minutes to firm up.
- Frost the cooled cupcakes with the blueberry frosting.
Notes
Ensure all ingredients are at room temperature for a smoother batter. You can add more lemon zest for additional flavor or use a piping bag for frosting.
