Apple Bars

Dave took these to work, and the pan was gone by noon. Pretty typical for his co-workers.

Apple Bars
Crust
2 cups flour
1/2 cup butter
1 cup sugar
1 tsp. vanilla
1 egg
Topping
3 large apples, sliced
2/3 cup brown sugar
4 Tbsp. butter
2 tsp. cinnamon

Preheat oven to 350ºF. Mix crust ingredients together until crumbly. Pat into lightly greased 8 x 8 pan. Layer fruit on top of crust. Mix together brown sugar, butter and cinnamon until crumbly. Sprinkle over fruit. Bake for 50 minutes to 1 hour, until fruit bubbles and topping is golden brown. Cut into bars while still warm.
