This is a very simple, yet very tasty, snack bar recipe. I like to use half regular variety Cheerios and half Multigrain Cheerios, but you can use any variety you like. You might also try mixing in some dried fruit or chocolate chips, but I prefer them as is. Especially if you use Multigrain Cheerios, this is a healthier bar than Rice Crispy treats. My whole family likes them, and they are great to make with kids. (Obviously, supervision is needed for the stove with younger children, but an older child can make these themselves.) Prep time includes cooling time.
