In a medium sized saucepan, add cocoa powder, butter, milk, and sugar
On medium heat, bring ingredients to a boil, mix, and boil for 3 minutes
While waiting, in a large mixing bowl, add oats, pumpkin purée, and peanut butter and set aside
Now that your mix has boiled for 3 minutes, turn off heat and pour over the oat mix
Mix well and scoop a spoonful at a time onto a parchment paper lined pan
After you scooped out all your cookie mix, let cookies cool for a couple hours or until hardened (put in the fridge for a quicker result)
