FAQs
Can I use regular marshmallows instead of mini marshmallows?
Yes, regular marshmallows can be used, but mini marshmallows distribute more evenly throughout the bars, giving a better texture in every bite.
How do I prevent the bars from sticking to the pan?
Grease the baking pan well or line it with parchment paper before spreading the mixture. Allowing the bars to cool completely before cutting also helps prevent sticking.
