Add 1 cup of your favorite candy chips (chocolate chips, toffee chips, peanut butter chips, etc.) to separate heatproof jars with 1/4 cup heavy cream in each. For marshmallow sauce, add 1 cup marshmallow creme and 2 to 3 tablespoons water to a heatproof jar.

Put the jars in a slow cooker and fill the insert with enough water to go above the level of the ingredients in the jars. Cover and cook for 2 hours on high, then stir each sauce to combine. Set on low to keep the sauces warm during a party.
