2 c butter
2 c sugar
2 c brown sugar
4 eggs
2 tsp vanilla
4 c flour
5 c blended oatmeal (blend in blender to a fine powder)
1 tsp salt
2 tsp baking powder
2 tsp baking soda
Add: 24 oz chocolate chips, 1 8-oz grated Hershey bar, and 3 cups chopped nuts. Bake at 375 degrees for 10 minutes.
This can be cut in half (it makes a ton). The oatmeal flour seems to help these be soft, but firm. If you just soften the butter rather than melting it, that will also help it to not go flat. If the first tray is not nice and fluffy, refrigerate dough for an hour and try again.
