Frequently Asked Questions:
Can I make these cookies ahead of time?
Yes, you absolutely can! You can prepare the cookie dough balls and store them, covered, in the refrigerator for up to 2 days, or freeze them for up to a month. Bake them from frozen, adding a few extra minutes to the baking time. Just be aware that the marshmallow might not get quite as toasted and gooey if baked from frozen, but they will still be delicious.
What kind of potato chips work best?
The recipe calls for plain, salted potato chips for their salty crunch and neutral flavor. Ruffled chips tend to hold their shape and texture better than thin, delicate ones. Avoid flavored chips, as they can overpower the other flavors in the cookie.
My marshmallows aren’t toasting. What can I do?
To ensure your marshmallows toast nicely, it’s often best to place the cookies under the broiler for the last minute or two of baking, watching them very carefully to prevent burning. Alternatively, you can lightly toast them with a kitchen torch after the cookies have cooled slightly.
