FAQs
Can I use regular marshmallows instead of marshmallow fluff?
Yes, you can melt regular marshmallows with a little bit of butter to create a similar spreadable layer, although marshmallow fluff gives a smoother texture.
Do I need to freeze the dough before baking?
Freezing the dough helps it hold its shape when layering and baking, preventing the bars from spreading too thin. It’s recommended but can be skipped if short on time.
