Allow me to set the super-spooky stage: a tender, oatmeal cookie base with rich peanut butter swirled in and colorful M&Ms studded throughout. This, topped with a melty peanut butter cup as well as a dark chocolate ganache. That all sounds delicious, but the taste isn’t even the best part⏤ these Peanut Butter Spider Cookies also happen to be the most adorable Halloween cookies ever.
