The engineering of the dessert explains why copycat home recipes frequently fail. At the foundation sits a soft almond extract sponge. It differs notably from standard vanilla chiffon: the slight nuttiness balances the intense natural sugars of cooked raspberry puree and ripe fruit. The sponge must retain moisture without turning soggy under heavy berry juices.
The signature element remains the Chantilly cream frosting. Rather than standard royal icing or sugary buttercream, Publix blenders whip cold heavy cream alongside a stabilized mascarpone cheese blend. The cheese adds rich lactic acid notes and thick fat solids, allowing the frosting to hold sharp piping edges without melting at room temperature.

A fresh berry filling, consisting of sliced strawberries, blueberries, raspberries, and blackberries, is layered between the tiers alongside a thin spread of seedless raspberry jam. The jam seals the sponge crumb, preventing excess fruit moisture from seeping directly into the cake foundation.
