FAQs
Can I use regular marshmallows instead of mini marshmallows?
Yes, regular marshmallows work fine, but mini marshmallows distribute more evenly throughout the bars for better texture.
Can I prepare these bars ahead of time?
Absolutely! You can make the bars a day in advance and store them in an airtight container. This allows the flavors to meld and makes cutting easier once chilled.
