Just saw this recipe on the Krafts foods website, and I think that it would great for a demo (Valentine's)... only instead of using a Chips Ahoy cookie, maybe use refridgerated cookie dough and bake on stone and then top with the other stuff (of course, not use the Cool Whip from a can but use the EAD)... would be a fairly quick, easy demo, not sure how many products you would actually use, but a fair number I'd think...
