A tender, buttery coffee cake layered with a sweet, slightly tart blueberry filling. Fresh or frozen blueberries are gently cooked with a touch of sugar and thickened with cornstarch to create a luscious filling that sits between two layers of soft, lightly crumbly cake. A buttery streusel topping adds a golden, crunchy finish. Perfect for breakfast, brunch, or a sweet afternoon treat.
