From my Ma's recipes for you folks with no ovens:

In a large sauce pan mix up:

2 C white sugar
1/4 C cocoa
1/2 C milk
1/2 C butter/marg

Put over mid heat and stir until boiling. Remove from heat and let rest for one minute.

Mix in:
1tsp vanilla
1/2 tsp salt
1/2 C peanut butter
3 C quick-cooking oatmeal

Drop mix by teaspoons onto waxed paper (mebbe glass/ceramics would be OK -- use a spatula to remove when set). Let cool until set.
