When I'm freaking out for chocolate but have none in the house, I make these 7-ingredient cookies. They're fast and easy, and I usually have everything I need to make them.
1 stick of butter
2 cups of sugar
3 T cocoa
1/2 cup milk
1/2 cup peanut butter
3 1/4 cups oatmeal (quick cooking works best)
4 t vanilla
Bring first 4 ingredients to a boil (make sure it boils or they won't set up). Remove from heat. Add the peanut butter (stir), then the vanilla (stir), then oatmeal (stir). Drop by spoonfuls onto wax paper. They should be a little runny ... they'll firm up on the paper.
