Preheat oven to 350 degrees. Line a 9x9 baking dish with parchment paper. If your parchment paper isn't sticking, you can lightly spray some non-stick cooking spray between the baking dish and parchment paper and that will help it stick.

In a large bowl add the first six ingredients and mix well. Using your hands or a fork, add the cold butter and mix until crumbly and coarse. Pour and press half of the crust mixture into the prepared baking dish. Bake for 10 minutes, or until set.

Once the crust is done setting gently spread the filling ingredients over the crust. Crumble the remaining crust mixture over the top.

Bake 40-50 minutes, or until set and lightly browned.
