This blueberry crumb cake recipe is made with a food processor for easy preparation. The cake is moist and tender, with a sweet and tangy blueberry filling and a crunchy streusel topping. The streusel is made with flour, sugar, butter, and cinnamon, and is mixed in the food processor until it forms coarse crumbs. The cake batter is also made in the food processor, with butter, sugar, eggs, flour, baking powder, and milk. The blueberries are folded into the batter and the streusel is sprinkled on top before baking. This cake is perfect for breakfast, brunch, or dessert.
