Ingredients

  • 3 eggs
  • 1 tablespoon vanilla extract
  • 1 tablespoon vinegar
  • 1 and 1/4 cups (250g) sugar
  • 1/2 cup (120ml) oil
  • 50ml freshly squeezed orange juice
  • Zest of 2 large oranges
  • 2 and 1/4 cups (300g) all-purpose flour
  • 2 tablespoons cornstarch
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt

Directions

  • Step 1: Preheat your oven to 350°F (180°C) and grease a 9-inch round cake pan. You can also line the bottom with parchment for easy release.
  • Step 2: In a blender, add eggs, vanilla, vinegar, sugar, oil, orange juice, and orange zest. Blend until smooth and frothy.
  • Step 3: In a separate bowl, sift together flour, cornstarch, baking powder, and salt. This helps avoid clumps and gives the cake a fine crumb.
  • Step 4: Gradually add the dry mixture to the blender, pulsing gently until just combined. Avoid over-blending so the cake stays fluffy.
  • Step 5: Pour the batter into the prepared pan and bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean.
  • Step 6: Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Dust with powdered sugar or drizzle with orange glaze if desired.
