Blueberry and Blackberry Crisp

 My goodness this year has sailed by! Here it is the end of summer and I'm just now posting a berry dessert. But this berry crisp is also wonderful made with frozen berries, so I had to go ahead and post it. I have made this Blueberry and Blackberry Crisp several times this summer, plus I've made it with blueberries only which is just as yummy. I've added a bit extra sugar to this recipe with the blackberry addition as the frozen berries I bought were more tart than the blueberries.

 This Blueberry and Blackberry Crisp is so easy to put together and the topping is a whiz to prepare. Plus, this topping actually is very crisp which has made it a favorite of ours. Of course topping this crisp with a good quality vanilla ice cream makes irresistible! Hope you'll give it a try!

Blueberry and Blackberry Crisp
Adapted from Martha Stewart
Fresh or frozen berries may be used, but baking time may increase if using all frozen berries. The filling is juicy. If a thicker filling is desired add another teaspoon or 2 of cornstarch.

Ingredients:
For the filling:
4 cups blueberries - I used fresh
2 cups blackberries - I used frozen this time
2/3 cup sugar ( when I make all blueberry crisp, I reduce to 1/2 c.)
1 tablespoon cornstarch
1 teaspoon fresh lemon juice
1/4 teaspoon sea salt

For the Topping:
3/4 cup unbleached all-purpose flour
1/2 cup quick oats ( may use rolled oats)
1/2 teaspoon baking powder
1/2 teaspoon sea salt
6 tablespoons melted, unsalted butter
1/3 cup sugar
1/2 teaspoon cinnamon

Directions:
1. Preheat oven to 375 degrees. Make filling by mixing berries, sugar, cornstarch, lemon juice and salt in a bowl. Poor berry mixture into an 8x8 inch baking dish with 2 inch sides.
2. Make topping- Stir together the flour oats baking powder, sugar, cinnamon, and salt.
Pour butter over topping and stir until it is absorbed and the topping is crumbly.
3. Sprinkle topping evenly over the filling. Place dish on a foil lined baking sheet just in case it bubbles over. (I haven't had that problem, but some commenters on Martha's site did.)
Bake until crisp is bubbling around the sides and in the center and brown on top, about 1 hour. Remove from oven and cool on a wire rack at least 30 minutes before serving. Top with ice cream and enjoy!
