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.
