Lemon Berry Crumble Bars

These bars were nice to make because they were pretty versatile. Any type of berry could be used (I used raspberry) and I also only made half of the recipe in an 8x8 pan. They were quick and easy and pretty tasty!

INGREDIENTS
1 cup white sugar
1 teaspoon baking powder
3 cups all-purpose flour
1 cup unsalted butter
1 egg1 teaspoon pure vanilla extract
1/2 teaspoon kosher salt
2 teaspoons lemon juice
2 cups fresh or frozen blueberries
2 cups fresh or frozen raspberries
1/2 cup white sugar
3 teaspoons cornstarch

DIRECTIONS
Preheat the oven to 375 degrees F (190 degrees C). Line a 9×13 inch pan with parchment paper and spray with nonstick cooking spray. Stir together 1 cup sugar, 3 cups flour, salt, and baking powder in a medium bowl.
In a separate, small bowl, beat together the egg, lemon juice, and vanilla. Using a pastry cutter or food processor, cut the butter and egg mixture into the flour to form a crumbly dough. Press half of dough evenly into prepared pan.
In two additional bowls, mix together 1/4 cup sugar and 1 1/2 teaspoons cornstarch. Gently mix blueberries into one bowl and raspberries into the other. Sprinkle berries evenly over pressed dough — I did half the pan with blueberries and half with raspberries, but you could alternate or even mix the berries if you’d rather. Crumble the rest of the dough over top of the berries.
Bake in preheated oven for 45 minutes or until slightly brown. Cool completely (and even chilling a little helps to ensure they’ll hold together) before cutting into squares.
