This post has taken a long time before posting and so I have forgotten the recipe I used for the Make Ahead Oatmeal Cookies.
Anyway, when the ingredients have been mixed, I cut the mixture in half and put it in the freezer. The left-over mixture did not harden and was used two days after these cookies were baked. I flattened the balls a bit before baking.
I remember using oatmeal flour, peanut butter, cocoa powder, tablea bits and canola oil.
Note to self: take notes.
