1 cup Heaping cup of wild blueberries frozen. You can also use fresh blueberries.
1 tablespoon All-purpose flour to coat the blueberries

Preheat the oven 350°F. Spray an 8X8-inch square pan with baking nonstick spray. Line the bottom and 2 sides with parchment paper and spray again.
In a medium bowl, mix the brown sugar, sugar, salt, cinnamon, and flour. Add in the melted butter and use a fork to mix until combined. Place in the fridge while you make the batter.
¼ cup Brown sugar, ¼ cup White granulated sugar, ¼ teaspoon Salt, ½ teaspoon Ground cinnamon, ¾ cup All-purpose flour, 5 tablespoon Unsalted butter

In a medium bowl, mix the flour, baking powder, baking soda, and salt. In a small bowl, combine blueberries and flour. Set aside.

Using a mixer, beat the sugar and butter on high speed for 2 minutes. Then, add in the eggs, vanilla, sour cream, and milk. Mix on medium speed until completely combined.
½ cup Unsalted butter, 1 ¼ cup White granulated sugar, 2 Large eggs, 2 teaspoon Pure vanilla extract, ½ cup Sour cream, 2 tablespoon Milk
Add in the dry ingredients and mix on low speed until just combined. Take off the mixer. Add in the blueberries and use a rubber spatula to gently mixed it in.
Spread the batter into the pan. Take the crumble out of the fridge and sprinkle it on top.
Bake for 55-60 minutes. Bake until a toothpick inserted comes out clean.
Let the cake sit in the hot pan for 10 minutes before transferring to a cooling rack. Let it cool completely before adding the glaze.
