2 cups oatmeal
1 cup brown sugar
1/2 cup margarine [I used butter]
1/4 teaspoon soda [i.e. baking soda]
Cream margarine; add brown sugar. Mix in remainder to crumbly mixture and press into pan. Bake until brown.

Did it Work?
Yes. This is very simple, but fairly rich press-in pan cookie. Basically, you end up with a concentrated version of crumble topping. The simplicity of the recipe would probably make it a great one to do with kids, especially since there is no risk of over-mixing.
Important details: Use an ungreased 8x8 pan. Try and smooth the top as much as possible or it will crumble later. Bake in a 350 degree oven for 12 to 15 minutes, watching carefully as it can burn easily. Cut while still warm, or you will have a rock in a pan.
