Strawberry cake's a southern celebration, often appearing on Juneteenth picnic tables. Traditionally, it's plain cake layered with strawberry buttercream. I've always wanted more strawberry flavor, so I put it in the cake and topping here. Dehydrated strawberries, now sold everywhere as snacks, moisten and soften in a cream cake batter, delivering super berry sweetness. Fresh berries get to shine all by themselves, sitting pretty in a whipped cream cloud.
