Notes
FAQ Section
Can I use large marshmallows instead of mini?
Yes, but it’s best to cut them into smaller pieces to help them melt evenly and distribute nicely in the dough.
Can I make these cookies gluten-free?
Absolutely! Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend.
Why did my marshmallows disappear in the oven?
This can happen if they melt too much. Try partially freezing the mini marshmallows before folding them into the dough to help them hold their shape.
