Step-by-Step Instructions
- Preheat your oven to 350°F (177°C) and grease and flour two 9-inch round cake pans.
- In a large mixing bowl, whisk together 2 cups of cake flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt.
- Cream together ½ cup of unsalted butter and 1 cup of granulated sugar until light and fluffy, about 3-5 minutes.
- Gradually add 4 egg whites, followed by ¼ cup of vegetable oil and 1 teaspoon of vanilla extract, mixing until smooth.
- Alternately add the dry flour mixture and 1 cup of buttermilk on low speed until just combined.
- Divide the batter evenly between the prepared pans and bake for 28–32 minutes, or until golden.
- Allow the cakes to cool in the pans for 5 minutes before transferring them to a wire rack to cool completely.
- In a medium bowl, combine ½ cup of berry jam with 2 tablespoons of water and fold in 1 cup of fresh mixed berries and lemon juice and zest.
- Beat 8 ounces of mascarpone cheese and 8 ounces of cream cheese until smooth, then add 1 cup of powdered sugar and 1 cup of heavy whipping cream until fluffy.
- Level the cake layers, spread a layer of filling on one cake layer, add frosting, and top with the second layer. Refrigerate for 30 minutes.
- Use remaining frosting to cover the top and sides of the cake.
- Garnish the top with fresh berries before serving chilled.

Notes
Ensure all ingredients are at room temperature for the best texture. Chill frosting if too soft to spread. Serve chilled for optimal flavor.
