This blueberry coffee cake is a delicious and easy dessert that's perfect for breakfast or a midday snack. The cake is made with fresh blueberries and a crunchy streusel topping, which gives it a sweet and nutty flavor. To make this cake, you'll need flour, sugar, baking powder, salt, milk, eggs, vanilla extract, butter, fresh blueberries, and brown sugar. Mix the dry ingredients together, then add the wet ingredients and mix until smooth. Fold in the blueberries and pour the batter into a greased baking dish. Mix the brown sugar and butter together to make the streusel topping, then sprinkle it over the batter. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool before serving.
