Upside-Down Cakes are a type of cake that is baked with fruit placed at the bottom of the pan. When the cake is finished baking, it is flipped over, revealing the fruit on top. This method creates a beautiful presentation and allows the fruit to caramelize, adding flavor and moisture to the cake. Common fruits used in Upside-Down Cakes include pineapple, apples, and peaches. The cake batter is typically a simple mixture of flour, sugar, eggs, and butter. This dessert is popular for its unique appearance and delicious taste, making it a favorite for gatherings and celebrations.
