Step-by-Step Instructions
- Preheat your oven to 350°F (177°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.
- In a large mixing bowl, whisk together cake flour, baking powder, baking soda, and salt.
- Cream together unsalted butter and granulated sugar on medium speed until light and fluffy.
- Gradually mix in egg whites, vegetable oil, and vanilla extract.
- Alternately add dry ingredients and buttermilk to the batter, mixing just until combined.
- Divide the batter between the prepared pans and bake for 28-32 minutes.
- Cool the cakes in the pans for 5 minutes, then transfer to wire racks.
- Mix berry jam and water in a bowl until smooth. Toss fresh berries with lemon juice and zest.
- Beat mascarpone cheese and cream cheese until creamy, then add powdered sugar and fold in heavy cream.
- Level the cooled cake layers, spread berry jam and frosting between layers, and apply a crumb coat.
- Frost the top and sides of the cake with the remaining frosting and top with fresh berries.

Notes
Ensure all ingredients are at room temperature for smoother mixing. Assemble and decorate the cake no more than a day in advance to maintain freshness.
