FAQ

Can I use store-bought marshmallow fluff?

Yes! While homemade fluff is more flavorful and airy, store-bought marshmallow fluff works just fine.

What if I don’t have a candy thermometer?

You can test the sugar syrup by dropping a small amount into cold water. If it forms a soft ball, it’s ready.

How do I prevent my ganache from getting too thick?

If it thickens too much, gently reheat it over a double boiler and stir in a teaspoon of warm cream.

Can I make these ahead of time?

Yes! Bake the cookies a day in advance and store in an airtight container. Assemble with marshmallow and ganache just before serving.
