This is a quickie bar cookie that I've made forever, and always get groans of appreciation. I don't know where the name came from, it's a family recipe from about 40 years ago. It literally took me less time to prepare this morning than the oven took to preheat.
1 1/2 cups AP flour
1 1/4 cups rolled oats
1 cup brown sugar
3/4 cup cold butter
3/4 cup preserves (I use my homemade strawberry or peach)
Stir dry ingredients together, cut in butter till crumbly. Press half of mixture firmly into 8" greased square pan. Spread preserves on top, keeping preserves away from the edges by about 1/4" (it sticks to the pan), sprinkle the rest of the sugar/oats mixture evenly on top of preserves and press again.
Bake at 325' for 45 minutes. Cut when cool into small bars.
If you want them pretty, cut off the edges (you get to eat all those yourself).
Don't use margarine - it makes them soggy instead of crispy.
The crumbs are wonderful over vanilla ice cream or mixed into Greek yogurt.
