This blueberry crumb cake coffee cake is a delicious and easy-to-make breakfast or dessert. The cake batter is made in a food processor, with flour, sugar, baking powder, salt, butter, eggs, and milk. The blueberries are folded into the batter and the streusel topping is made with flour, sugar, butter, and cinnamon, mixed in the food processor until it forms coarse crumbs. The cake is baked until golden brown and the streusel is crunchy. This coffee cake is perfect for a special occasion or a lazy weekend breakfast.
