Mixed Berry Crumb Bars

A long absence, I know! I really won't be back on a normal schedule until after July 15th. Finishing my residency and moving has all taken over my life temporarily! I promise I will be posting on a regular schedule again soon!

Mixed Berry Crumb Bars, adapted from Smitten Kitchen

1 cup white sugar
1 teaspoon baking powder
3 cups all-purpose flour
1 cup cold unsalted butter (2 sticks or 8 ounces)
1 egg
1/4 teaspoon salt
Zest and juice of one lemon
2 cups fresh blueberries

2 cups fresh raspberries
1/2 cup white sugar
4 teaspoons cornstarch

1. Preheat the oven to 375 degrees F (190 degrees C). Grease a 9×13 inch pan.

2. In a medium bowl, stir together 1 cup sugar, 3 cups flour, and baking powder. Mix in salt and lemon zest. Use a fork or pastry cutter to blend in the butter and egg. Dough will be crumbly. Pat half of dough into the prepared pan.

3. In another bowl, stir together the sugar, cornstarch and lemon juice. Gently mix in the berries. Sprinkle the berry mixture evenly over the crust. Crumble remaining dough over the berry layer.

4. Bake in preheated oven for 45 minutes, or until top is slightly brown. Cool completely before cutting into squares
