Spiced Plum Crumble is a delicious dessert made with juicy plums, warm spices, and a crunchy crumble topping. The plums are gently cooked with cinnamon, nutmeg, and a touch of sugar, creating a sweet and tangy filling. The crumble topping is made with a mixture of oats, flour, butter, and brown sugar, which bakes to a golden brown and adds a delightful texture. Serve this warm dessert with a scoop of vanilla ice cream for the perfect balance of flavors.
