Chex was coming out with an Apple Cinnamon flavor, we couldn't wait to try it! I have to admit that I love the fact that General Mills is reaching out to the gluten free community, for example through glutenfreely.com. It's about time that a major company realized how much money there is to be made by properly labeling gluten free food, and I know that I vote with my dollars.
That said - I hate to say it, but as soon as I got my hands on a box of Apple Cinnamon Chex? ... Not that big of a fan. There's a very strong apple taste that overpowers the cinnamon flavor, and it doesn't quite go well with milk. I love their Cinnamon Chex, and think that their current Cinnamon Chex would have been a better place to start for an apple cinnamon flavor.
My suggestion: Combine some Cinnamon Chex with Rice Chex to tone down the cinnamon flavor, and add dried apples to make them "apple cinnamon."
That said - I'm glad that General Mills is innovating and creating new products. Now if only Post and Kelloggs would follow suit and add more options than Fruity/Cocoa Pebbles and Gluten Free Rice Krispies!
