Frequently Asked Questions

Can I use large marshmallows instead of mini marshmallows?

Yes, chop large marshmallows into smaller pieces. They may create slightly larger gooey pockets but still work perfectly.

Why do my marshmallows melt completely?

Marshmallows can melt if overbaked or mixed too vigorously. Fold in gently and bake just until edges are set.

Can I make these cookies gluten-free?

Use a high-quality gluten-free all-purpose flour blend. Adjust liquid slightly if dough feels too dry.

How do I keep cookies soft?

Store in airtight containers at room temperature and avoid overbaking. Cooling completely before sealing helps retain moisture.
