Preheat the oven to 375 degrees F and grease a 9x13 baking pan with butter. Set the pan aside for now.
Start by making the crust/crumble mix. Add the flour, sugar, baking powder, cinnamon and salt to a large bowl and stir together.
3 cups flour, 1 cup sugar, 1 teaspoon baking powder, 1/4 teaspoon salt, 1/2 teaspoon cinnamon
Add the egg, vanilla, and cold cubed butter to the bowl. Use a fork to mix everything together until it is evenly blended and looks like coarse crumbles. You can also mix with your hands, rubbing the butter into the dry flour mix.
1 egg, 2 teaspoons vanilla extract, 1 cup butter
Pour half of the flour mixture into the greased baking pan. Spread the mix across the bottom pan to form an even layer then press down to make a firm crust. Set aside for now.
Next, make the filling. In a separate large mixing bowl, whisk the cornstarch, sugar, and lemon zest together. Add the blueberries and lemon juice and toss everything, mixing well.
1 Tablespoon cornstarch, 1/2 cup sugar, 1 teaspoon lemon zest, 4 cups fresh blueberries, 2 Tablespoons lemon juice
Pour the blueberry filling over the crust in the pan and spread it into an even layer.
Sprinkle the remaining flour mix over the top of the blueberry filling, making an even crumble topping.
Bake the bars for 40 minutes. The top will be a nice golden brown.
Let the bars cool in the pan for at least 30 minutes before cutting and serving.
