- Preheat the oven to 350°F (177°C) and prepare two 9-inch round cake pans by greasing with butter and dusting with flour.
- Mix 2 cups of cake flour, 1 tablespoon of baking powder, 1 teaspoon of baking soda, and ½ teaspoon of salt in a large bowl.
- Beat ½ cup of unsalted butter and 1 cup of granulated sugar until light and fluffy for 3-5 minutes.
- Gradually add 5 egg whites, mixing on low speed until combined.
- Mix in ½ cup of vegetable oil and 1 teaspoon of vanilla extract, then alternate adding dry ingredients and 1 cup of buttermilk.
- Divide batter between prepared pans, smooth the tops, and bake for 28-32 minutes until a toothpick comes out clean.
- Prepare filling by mixing ¾ cup of berry jam with 1 tablespoon of water, and toss 2 cups of fresh berries with juice and zest of 1 lemon.
- For frosting, combine 8 ounces of mascarpone cheese and 8 ounces of cream cheese, adding 2 cups of powdered sugar until smooth.
- Level cooled cake layers, spread berry jam mix on first layer, followed by frosting and half the lemon-tossed berries, then top with second layer.
