Ensure your butter isn’t too soft and chill the dough if needed.

What type of chocolate works best?
Dark chocolate (60% or higher) adds richness without being overly sweet.
Can I make these cookies gluten-free?
Yes, substitute all-purpose flour with a gluten-free blend.
How do I prevent the marshmallow from sticking to my hands?
