Warm yummy blueberry crumble with crispy oat topping.

This Blueberry Crumble is a delightful and easy dessert that showcases the natural sweetness of frozen blueberries. The filling, made with blueberries, sugar, and a hint of lemon juice, balances tartness with sweetness, while the oat-based crumble adds a perfect crunchy texture. No need to thaw the blueberries, making it convenient year-round. Bake until the topping is golden and the filling bubbles, then cool slightly before serving. It pairs wonderfully with a scoop of yogurt, some vanilla ice cream or a dollop of whipped cream for a comforting, crowd-pleasing dessert that’s both warm and refreshing.
