Notes
Measuring Flour: Use a food scale and weigh the flour in grams (see metric tab in recipe card above) for best results. If using measuring cups, use the spoon and level method.Lucky Charms Marshmallows: These can be picked out of the cereal box or bought separately as a bag of just the marshmallows. Other brands also make similar shaped marshmallows that work just as well.Storage: Store cookies in an airtight container at room temperature for up to 1 week. To keep them extra fresh, put a small slice of bread in the container with them! They can also be stored in the freezer for up to 1 month.Nutrition: The provided nutrition information is an estimate, the calorie accuracy is not guaranteed.
