These Pineapple Upside Down Cinnamon Rolls combine the classic gooey, fluffy cinnamon roll dough with a caramelized topping of pineapple rings, maraschino cherries, and brown sugar. Baked upside down in a buttery caramel base, then flipped to reveal a golden, sticky tropical fruit topping, they make a visually stunning and delicious brunch or dessert treat perfect for summer gatherings.
