Common Recipe Questions

How do I prevent marshmallows from leaking during baking?

Wrapping the dough completely around the marshmallow and chocolate helps contain the filling and prevents leakage during baking.

Can I substitute dark or white chocolate for milk chocolate?

Yes, feel free to swap milk chocolate squares with dark or white chocolate to suit your taste preferences.

What is the best way to get crispier edges on these cookies?

Baking the cookies for an additional 2 minutes beyond the suggested time helps create crispier edges while maintaining a soft center.

Can I use graham cracker crumbs instead of pieces?

Yes, using graham cracker crumbs results in a smoother texture while still delivering that signature flavor.

Should these cookies be served warm or cooled?

Serving the cookies slightly warm enhances the gooey texture by keeping the marshmallow and chocolate melted.
