Blueberry Crumb Bars

I made these because I had a flat of leftover blueberries that needed to be used. The result was the most delicate, crumbly, sweet treat that I will most certainly be using again. Since I cannot (I mean should not) eat the entire pan, I am sending the remaining bars, cut into small pieces and wrapped in Wax paper to work with my hubby tomorrow, just to be extra sure that I don't eat them throughout the day :)

Blueberry Crumb Bars

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
4 cups fresh blueberries
1/2 cup white sugar (for blueberries)
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, combine one cup sugar, flour, and baking powder, mix well. Add salt and lemon zest. Using a pastry cutter, blend in the butter and egg. Your dough should be crumbly. Pat half of dough into the prepared pan.

3. In another bowl, stir together the ½ cup of sugar, cornstarch and lemon juice. Gently mix in the blueberries. Sprinkle the blueberry mixture evenly over the crust. Crumble remaining dough over the berry layer.

4. Bake in preheated oven for 50 minutes, or until top is slightly brown. Cut into small squares once cooled.
