This lemon blueberry crumb cake recipe is a delicious twist on the classic. The cake is moist and tangy, with a sweet blueberry filling and a crunchy lemon crumb topping. To make the cake, you'll need flour, sugar, baking powder, salt, butter, eggs, milk, lemon zest, lemon juice, vanilla extract, and fresh blueberries. 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. To make the crumb topping, mix flour, sugar, butter, and lemon zest until crumbly, then sprinkle over the cake batter. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. Serve warm or at room temperature.
