In a pan, combine 1 stick margarine, 1/2 cup milk, 2 cups sugar Cook over med heat until it comes to a rolling boil. Let it boil for 1 minute, keep stirring then add 2/3 cup peanut butter-(I use 2 big spoonfuls) and 1 tsp vanilla extract.
Remove from heat and add 3 cups oatmeal 3 Tbsp cocoa. Drop by spoonfuls onto aluminum foil. Wait a few minutes-(if you can) and enjoy.
