This apple upside-down cake is a delicious and unique dessert that is perfect for any occasion. The cake is made with fresh apples, cinnamon, and a touch of nutmeg, and is then topped with a caramelized brown sugar and butter mixture. The cake batter is made with a combination of butter, sugar, eggs, and flour, and is then poured over the apple mixture. The cake is then baked until golden brown and is best served warm with a dollop of whipped cream or a scoop of vanilla ice cream.
