Fans of Rice Krispie treats will fall hard for this dessert, which tweaks the classic into a chocolate-and-coffee ice cream sammie. Cocoa Puffs take place of the crispy rice cereal, making these sandwiches a chocolate-lovers fantasy. And it doesn’t stop there. Layered between the chewy treats is a generous helping of Nutella and a cool and creamy dose of creamy coffee ice cream. Assembling the sandwiches in the pan before they're chilled means they’re ready-to-eat as soon as they’re frozen. Simply slice and serve—with plenty of napkins! Not a fan of Cocoa Puffs? Feel free to swap ‘em out with the cereal of your choosing.
