If you're a marshmallow lover, you may have nuked a few genius combos in your day, but chances are you've never crossed the gourmet rubicon to concoct, say, a marshmallow cake. And I'm not talking about a few ribbons of marshmallow laced through tasteless white sponge with a few sugary pillows folded in for decoration. 240sweet has broken ground with a cake made entirely of marshmallow—the springiest, thickest marshmallow your sweet tooth has ever come across, straight from the heart of Indiana, where the cake is handcrafted with only natural gluten-free ingredients. It is huge—10 by 3 inches—and adorned with rich toppings: The praline variety comes with New Orleans pecan beauties and swirls of salty caramel, which pools at the bottom onto more pralines. You can also go with Salty Caramel (hold the nuts), Turtle, or Caramel Chocolate Chip. Set one of these out on the candy table around Halloween and watch everyone freak out (not in a scary way). And don't be surprised if Aunt Dotty's pumpkin pie gets the shaft this Thanksgiving.
