Frequently Asked Questions

How do I keep the marshmallow from melting too much?

Use mini marshmallows instead of fluff, as they hold their shape better during baking.

Can I make these cookies ahead of time?

Yes! You can refrigerate the dough for up to 24 hours before baking.

Why did my cookies spread too much?

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

Can I use regular-sized marshmallows?

Yes, but cut them into smaller pieces to distribute them evenly.

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?

Lightly grease your hands or use a spoon when incorporating the marshmallow.

Can I use oil instead of butter?

Butter is recommended for the best texture, but coconut oil can be a substitute.

What’s the best way to get a perfect swirl?

Use a toothpick or knife to gently swirl the marshmallow through the dough.
