This is a basic oatmeal bar base you can use any flavor of jam with. Cranberry jelly is perfect for Christmas or Thanksgiving, or any holiday occasion.
Mix the first 4 ingredients together, then take the butter and cut it in, until it's perfectly crumbly. I find that rubbing it between your palms lightly works so well.
Firmly press 2/3 of the mix into a greased 9 inch x 9 inch pan.
Once the bottom layer is done, pour the cranberry sauce, or jelly, on top and spread out in an even layer.
Crumble the rest of the topping over the jelly.
Bake in a 350 degree oven for 35-40 minutes until it's a lovely brown color and crisp on top.
Cool this completely and then slice into 25 squares. It is crumbly but if you are patient and cool it for a long time, they hold together.
Notes
Because you don't make the filling, you can use as much OR as little cranberry sauce for the filling layer as you like in these bars!
