Start by toasting two pieces of bread. After toasting, generously butter both slices on one side and sprinkle 'em with cinnamon and sugar. Spread the other side of the bread slices with Nutella and add a couple of ooey-gooey roasted marshmallows on top of one of the slices (the Cinnamon Churro Smashmallows are a game-changer). Put the remaining piece of cinnamon toast on top of the marshmallows, cinnamon side up. Enjoy!
