Girl Scout Tagalong cookies have been around since the '70s, channeling peanut butter chocolate lovers. Sure, the cookie is great alone, but I discovered marshmallows make them even better.

Chill the dough for 20 minutes if the marshmallows are melting too quickly. Use a cookie scoop for evenly-sized cookies. Don’t overbake! Cookies should be soft in the middle for the best texture.
