S'mores Indoors: Retro Ad & Recipe

I recently came across this cool Retro Ad for S'mores Indoors from golden Grahams Cereal and Nestle Chocolate Morsels. I'm a big fan of all kinds of S'mores. I'll be adding this recipe to my S'mores Recipe Round-up on National S'mores Day this summer. Of course you can change of the original ingredients using your favorite graham cereal and chocolate. So if you're not in outside camping this weekend, here's a great way to bring the great outdoors in! Who doesn't love S'mores?
