- Preheat your oven to 180°C (350°F) and grease and line two 8-inch round cake pans with parchment paper.
- Sift together all-purpose flour, cornstarch, baking powder, and a pinch of salt in a medium bowl.
- Combine milk and vinegar in a separate bowl and let sit for 5 minutes to make buttermilk.
- Cream together unsalted butter, vegetable oil, and granulated sugar on medium speed for 3 minutes.
- Gradually add egg whites one at a time, mixing well after each addition.
- Add vanilla extract and half of the milk-vinegar mixture, mixing on low speed.
- Fold in half of the dry ingredient mixture, then the remaining milk mixture, and finally the rest of the dry mix.
- Gently fold in rainbow sprinkles until well dispersed.
- Divide batter evenly between prepared cake pans and bake for about 30 minutes, or until a toothpick comes out clean.
- Let the cakes cool in the pans for 15-20 minutes, then invert onto wire racks to cool completely.
