Ingredients:

  • 1 cup cake flour
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/3 cup vegetable oil
  • 1/3 cup whole milk
  • 3 large egg yolks
  • 1 tsp vanilla extract
  • 3 large egg whites
  • 1/4 tsp cream of tartar
  • 1/2 cup granulated sugar

Instructions:

  1. Preheat your oven to 325°F (160°C) and line your cupcake pan.
  2. Sift the cake flour, baking powder, and salt into a large bowl to ensure no clumps.
  3. Whisk in the vegetable oil, milk, egg yolks, and vanilla extract. Stir until the batter is smooth and glossy, but do not overmix.
  4. In a clean, grease-free bowl, beat the egg whites and cream of tartar on medium speed until frothy.
  5. Gradually add the granulated sugar one tablespoon at a time while increasing the speed to high. Beat until stiff peaks form.
  6. Take a small scoop of the meringue and stir it vigorously into the yolk batter to lighten the mixture.
