Method
 

Preparation

  2. In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt.
  3. In a large bowl, combine the granulated sugar and lemon zest and rub them together with your fingers.
  4. Add vegetable oil and melted butter, whisking until combined. Then, add eggs, lemon juice, vanilla extract, and sour cream.
  5. Fold the dry ingredients into the wet mixture until just combined.
  6. Divide the batter among the cupcake liners, filling them 3/4 full.
  7. Bake for 15-20 minutes, checking with a skewer for doneness. Cool in the tin for 5 minutes, then transfer to a wire rack.

  2. Set the blueberry mixture aside to cool completely.
