Apricot Squares

1 1/4 cup oats
1 1/4 cup flour (I often use whole wheat or white whole wheat & am still very happy with the results)
1/2 cup sugar
3/4 cup melted butter
1/2 tsp baking powder
1/4 tsp salt
2 tsp vanilla
12 oz. apricot preserves (or other flavor jam or preserves, just don't use jelly because it's too thin)

Combine all ingredients, except preserves, in a large bowl.  Reserve approximately 1 cup of crumb mixture and press the rest into a greased 13 x 9 baking dish.  Spread preserves over base.  Sprinkle with reserved crumb mixture.  Bake at 350 for 30 minutes.  Cool at least 10 minutes, cut into bars. 

Note: If you are having trouble covering the bottom of the pan, you can reserve less crumb for the topping, it will still work out fine.
