This recipe uses two types of Chex cereal... Cinnamon Chex and Corn Chex. The Cinnamon Chex cereal adds some really lovely cinnamon flavor to the mix, so I would not suggest substituting it in the recipe. However, you can use any other type of Chex cereal to replace the Corn Chex. Just keep in mind that if you are on a gluten-free diet that some of the Chex cereals do contain gluten.
