What To Avoid While Making Peanut Butter Marshmallow Cookies Recipe?

  1. Not Chilling the Dough Long Enough: Chilling the dough for at least an hour is crucial to prevent the cookies from spreading too much while baking.
  2. Using Fresh Marshmallows: Fresh marshmallows can melt too quickly in the oven and become sticky.
  3. Not Letting Cookies Cool on the Baking Sheet: Letting the cookies cool on the baking sheet is important. Moving them too early can cause them to break apart, as they are very soft when first out of the oven. Allow them to cool fully before transferring.
