Preheat oven to 375 degrees.

Grease a 9 x 13 baking pan.

In a large bowl, combine flour, 1 cup of sugar, baking powder, salt, and cinnamon.

Cut in 2 sticks of cold butter, and incorporate into flour mixture with a fork or pastry cutter until it’s crumbly.

Add egg and vanilla, and combine into flour mixture until it forms a dough-like crust mixture.

In a separate bowl, combine berries, 1/2 cup granulated sugar and cornstarch. You could add a little lemon juice to this for added flavor, but I didn’t have any on hand, so I didn’t.

Take 1/2 of your crust & topping mixture and pat it into the bottom of your greased 9 x 13 baking pan.

Spread berry mixture evenly over the top of the crust.

Sprinkle the remaining crust & topping mixture evenly over the berry mixture.

Bake in 375 degree oven for 35-40 minutes.
