Substitution for Marshmallow fluff?
Growing up in New England, whoopie pies were traditional Fourth of July fare and I've got some time on my hands and want to make my own. The problem? I live in the South and Marshmallow Fluff is impossible to find. The Marshmallow Fluff recipe (ssh, it's my grandmother's secret... don't tell!) calls for a 2:2:1 ratio of Fluff:confectioner's sugar:butter. Is there a substitution (marshmallow cream?) I can make for the Fluff that will keep it nice and, well, fluffy?
