I found this recipe in a magazine a few months ago. I've changed it to make only half the quantity of the two sauces recommended, because it was just way too much. Next time we make them I would also do it on individual plates instead of on one tray, for easier eating. (And plate licking.)
1/2 Tbl water
15 lg marshmallows
3 Tbl butter
4 medium apples, peeled, cored, and thinly sliced
Melt the caramels in the microwave, stir until smooth. (I did 60 seconds at 70%, stirred, and that much again.)
Meanwhile melt the marshmallows and the butter on the stove.
Arrange the apples (either on a big tray or on individual plates.)
Drizzle caramel and marshmallow cream, then sprinkle with nuts and chocolate chips.
