Don’t Overbake: Remove the cookies from the oven when they are slightly undercooked; they will continue to set as they cool.
Use Quality Ingredients: Opt for high-quality peanut butter and marshmallow fluff for richer flavor in every bite.
Adjust Flour Measurement: Depending on humidity, you may need to add a little more flour if your dough is too sticky.
Experiment with Add-Ins: Consider adding chocolate chips or nuts for extra texture and flavor variations.

Common Mistakes to Avoid

- Incorrect Oven Temperature: Baking at the wrong temperature can affect cookie texture. Use an oven thermometer to ensure it’s set to 350°F.
