Step 1: Preheat oven to 350º F.
Step 2: Spray a 9x13 baking dish with nonstick baking spray or spread with a thin coating of butter and then lightly flour the pan, removing any excess flour.
Step 3: In a large mixing bowl, whisk together 2 cups of flour, baking powder, salt, and sugars until well-combined.
Step 4: Combine milk and lemon juice and zest in a separate bowl; set aside.
Step 5: Pour 1/2 cup of melted butter into dry flour mixture and stir together until really well-combined with a rubber spatula. Add eggs one at a time, combining well after each addition.
Step 6: Add milk and lemon mixture to the batter and stir well.
Step 7: Gently fold in 1 1/2 cups blueberries.
Step 8: Pour batter into prepared baking dish.
Step 9: Sprinkle the 1/2 cup of blueberries from the topping ingredients onto the top of the cake batter. Then, sprinkle entire top of cake with 4 tablespoons of granulated sugar to form a sugary crust on the baked cake.
Step 10: Bake cake for 40-45 minutes until a cake tester or toothpick inserted in the center comes out clean. Allow to cool completely, about 15-20 minutes before serving.
