Let's get real, this summer fruit “cake" might not be much of a “cake" at all, but the tiered treat is still sweet and refreshing. There's no butter or eggs involved in this dessert. Instead, towering layers of watermelon and cantaloupe are stacked with a sweetened yogurt and whipped cream surprise filling! Serve poolside or bring one along to your next BBQ bash. We promise it will impress even those guests who go gaga for baked goods.
