This isn't exactly a healthy snack, but it sure is delicious and easy! :) Original recipe here.
It doesn't get much easier than this. Just mix one 8oz package of softened cream cheeese, one 7oz container marshmallow creme, a pinch of nutmeg, and 1/8 to 1/4 teaspoon of cinnamon together and dip your choice of fruit in it. Enjoy!
