Black and Blue Crumb Bars

These bars will blow any cobbler away.  Yes, I'm serious.
How could this be?!  Because you can enjoy these for breakfast or dessert with vanilla ice cream a la mode.  And who doesn't love some sweetness beyond the late night snack?  
Trust me; I tried them both ways in Seaside, Florida this past week for spring break.  No regrets, y'all.
I chill the bars for an easy cookie-like morning snack and pop them for 30 seconds in the microwave to get the ultimate, buttery crust you'd find in a pie.  Basically, these bars can and will please anyone!
black and blue berry crumb bars

makes approx. 36 small bars
1 cup white granulated sugar
1 teaspoon baking powder
3 cups all-purpose flour
1 cup cold unsalted butter (2 sticks)
1 egg
1/4 teaspoon salt
Zest and juice of 1 lemon
2 cups fresh blackberries
2 cups fresh blueberries
1/2 cup white granulated sugar
4 teaspoons cornstarch
1. Preheat oven to 375 degrees.  Grease a 9x13 inch pan and set aside.

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 your fingers 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 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.  Cool completely (you can even chill them in the fridge) before cutting into squares.
