Last week at a beach picnic, my friend Stephen (coffee aficionado, Big Green Egg aficonado, everything food aficionado) told me about a s'mores variation that I couldn't resist trying. He'd read about s'mores semifreddo online, abandoned it for being too complicated (home-made graham crackers and ice cream, who can blame him?), and struck out on his own with a pared down version using storebought ingredients and a little culinary improv.

Heat the broiler. Line a baking sheet with parchment and generously butter the parchment. Spoon the Fluff onto the parchment. Wet your hands and pat out the Fluff into a thin layer (see photos below) that nearly covers the baking sheet.
Place the Fluff under the broiler (about 6 inches from the flame) and toast all over. Remove the baking sheet from the oven. Using a spatula, turn in the sides of the Fluff, folding it like a letter, to expose the un-toasted portions. Place under the broiler and toast all over, again. Remove from the oven and let cool completely.
Put the graham crackers in a sturdy plastic bag, and using either a rolling pin or the base of a small saucepan, pound the crackers into coarse crumbs. Spread half of them in the base of an 8-inch baking dish.
Set out the ice cream for 10 minutes. Place it in the bowl of a mixer fitted with a paddle attachment (if you don't have a mixer, you can mix it by hand and skip the gym this week). With the mixer on low, mash the ice cream to loosen it a bit. Add the toasted Fluff and mix until just blended but not broken down -- you want there to be chewy bits. Scrape into the baking dish and freeze.
Meanwhile, melt the chocolate and oil in a double boiler, whisking until they're smooth.
To serve, spread the remaining graham cracker crumbs on top of the semifreddo. Drizzle the top with as much chocolate as you like! (You may also pass a pitcher of chocolate at the table, which your guests will appreciate.)
Before starting Food52 with Merrill, I was a food writer and editor at the New York Times. I've written several books, including "Cooking for Mr. Latte" and "The Essential New York Times Cookbook." I played myself in "Julie & Julia" -- hope you didn't blink, or you may have missed the scene! I live in Brooklyn with my husband, Tad, and twins, Walker and Addison.
