Wondermade marhmallows are made with 100% cane sugar. Cane sugar is sucrose; corn syrups are a mix of glucose and fructose in varying percentages. That means they bind to ingredients differently, they cook differently and your body processes them differently. Each marshmallow is 1″x1″, with 16 in every 4.5″x4.5″ box. There are 6 signature flavors: Gingerbread, Bourbon, Guinness, Pumpkin Pie, S’Mores and Peppermint.
