The pineapple upside-down cake is a classic dessert that never goes out of style. It's a moist and buttery cake topped with caramelized pineapple slices and maraschino cherries. The cake batter is usually flavored with a hint of vanilla or almond extract to complement the tropical flavors. When the cake is baked, it's inverted onto a serving plate, revealing the beautiful caramelized fruit on top. It's a deliciously nostalgic cake that kids and adults enjoy alike.
