Ingredients

Scale
  • 2 1/2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1 tablespoon baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon salt
  • 3/4 cup unsalted butter, softened
  • 1/2 cup vegetable oil
  • 5 large egg whites
  • 1 tablespoon clear vanilla extract (or regular)
  • 1 cup whole milk
  • 1/2 cup sour cream
  • Sprinkles (optional, for topping)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch sheet pan with parchment paper.
  2. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
  3. Add the softened butter and vegetable oil. Beat on medium speed until the mixture is crumbly.
  4. In another bowl, whisk together the egg whites, clear vanilla, milk, and sour cream.
  5. Gradually add the wet ingredients to the dry, beating until just combined and smooth.
  6. Pour the batter into the prepared pan and smooth the top with a spatula.
  7. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  8. Let the cake cool completely in the pan before frosting or adding sprinkles if desired.

Notes

  • Clear vanilla extract gives the cake that classic bakery flavor and bright white color, but regular vanilla works too.
  • Don’t overmix the batter to keep the cake tender.
  • This cake pairs beautifully with a whipped vanilla frosting or a light cream cheese frosting.
