Bake the Cake
- Heat oven to 350F. Butter two 9-inch round pans, line bottoms with parchment, and butter the parchment. Whisk together cake flour, baking powder, and salt in a bowl.
- Beat butter and sugar on medium-high speed until pale and fluffy, about 4 minutes. The mixture should look almost white and feel light when you scrape the bowl.
- Add egg whites one at a time, beating well after each addition. Scrape down bowl and beat in vanilla and almond extracts. The batter will look slightly curdled - this is normal.
- Reduce speed to low. Add flour mixture in three additions, alternating with milk in two additions, beginning and ending with flour. Mix just until smooth with no streaks of flour.
- Divide batter between pans and smooth tops. Bake until cakes spring back when lightly touched and a tester comes out clean, 25 to 30 minutes. Cool in pans 10 minutes, then turn out onto racks to cool completely.
Make the Chantilly Cream and Assemble
- Beat heavy cream on medium speed until soft peaks form, about 3 minutes. Add mascarpone, powdered sugar, and vanilla. Beat on medium-low until stiff peaks form, about 2 minutes more. Do not overbeat or cream will become grainy.
- Place one cake layer on a platter. Spread with 1 cup chantilly cream and top with half the berries. Add second cake layer, spread remaining cream over top and sides, and decorate with remaining berries. Chill at least 1 hour before slicing.
Notes
Cake flour is essential here - all-purpose will make the cake too dense. If you must substitute, use 2 1/4 cups all-purpose plus 1/4 cup cornstarch. The chantilly cream is best made the day you serve, but the cake layers can be baked a day ahead and wrapped tightly. For clean slices, dip your knife in hot water and wipe dry between cuts.
