This moist Blueberry Lemon Crumb Cake with Lemon Glaze is made with fresh blueberries and lemon zest, topped with an easy crumb topping and a sweet lemon glaze.
Preheat the oven to 350°F. Butter and line a 9x9 square metal baking dish with parchment paper.
Crumb Topping: Combine the butter, flour, brown sugar, and salt in a bowl. Use your hands to scrunch up the crumbs so that you get crumbs of various sizes.
Cake: In a large bowl, combine the whole milk, vegetable oil, eggs, vanilla extract, and lemon zest. Add the sugar, baking powder, salt, and flour, and combine. Add the blueberries and use a spoon to gently combine.
Assemble: Pour the batter into the prepared dish, spreading it to cover the dish evenly. Sprinkle with the crumb topping.
Bake for 35-40 minutes. Look for the cake to have a domed top and be set in the middle. Remove and allow to cool.
Lemon Glaze: In a small bowl, combine the lemon juice and powdered sugar. Drizzle the cake with the lemon glaze. Cut into squares and serve.
Notes
Whole Milk: Whole milk is best, but 1 or 2% can be used in a pinch.
Lemon: The zest of the lemon adds bright lemon flavor without any of the sourness of the juice. Be sure to zest only the bright yellow outer part of the lemon.
Blueberries: The amount of blueberries and the size of the blueberries will impact the baking time because it will affect the total water content of the cake.
