Made with a mix of blueberries and raspberries between a sweet crumb mixture, these Berry Crumble Bars are quick and easy to make, have a tender texture, and crazy delicious. Using fresh or frozen fruit, makes this crumb bar recipe a perfect year-round dessert.
Preheat oven to 375F. Line a 9x13 baking dish with parchment paper with a slight overhang on the 2 longer sides.
In a large mixing bowl, stir together the flour, 1 cup of granulated sugar, brown sugar, baking powder, cinnamon, and salt. Cut in the butter with a fork or pastry blender (or your hands) until mixture resembles coarse crumbs. Then stir in the egg and vanilla with a fork (dough should remain crumbly.)
Press half the crumb mixture firmly and evenly into the bottom of the prepared baking dish.
Wipe out the bowl used for the dough. Add in the remaining 1/2 cup sugar and the cornstarch, stir to combine. Dump in the berries and toss to coat.
Spoon the berries over the crumb mixture in the pan. Sprinkle with the remaining crumb mixture (making sure some of the berries still peak through).
Bake 40 to 45 minutes until golden and the filling is bubbly. Let cool completely before slicing into bars.

Notes
You can use fresh or frozen berries. I love the combo of raspberries and blueberries but feel free to use whatever berries you prefer.
