Fudge Filled Peanut Butter Cookie Cups aka Mud Puddles

These ‘Mud Puddle’ Cookies (or Fudge Puddles!) are a longtime favorite of ours! Don’t let the name ‘Mud Puddles’ fool you… no dirt used in this recipe! 😉

They’re actually peanut butter cookies filled with delicious fudge. They’re addictive! We make these every Christmas & put holiday sprinkles & m&ms right in the center. SO cute!


To make the holes that the fudge sits in – just press down in the center with a small spoon or melon baller as soon as the cookies come out of the oven to make a well.
