A moist and flavorful retro dessert that transforms a simple boxed cake with a strawberry gelatin soak. Topped with fluffy whipped topping, it's an easy, crowd-pleasing treat perfect for any occasion.
Ensure the gelatin is fully dissolved to prevent grittiness. Do not skip the chilling time, as it allows the gelatin to set and the cake to become perfectly moist. The cake can be made a day ahead.
