Peach-Cream Filling

The cake layers can be baked, cooled, and wrapped tightly in plastic wrap up to 2 days ahead and stored at room temperature. However, the peach-cream filling should be assembled no more than 6 hours before serving, as the whipped cream will begin to weep and deflate, and the peaches will release moisture that can make the cake soggy.

Store the assembled cake loosely covered with plastic wrap in the refrigerator for up to 24 hours. The cream will soften and the peaches will continue to release juice, so the texture is best within 6-8 hours of assembly. Do not freeze, as the whipped cream will separate and become grainy upon thawing.
