This is another one of those recipes that I would love to claim for my own, but cannot: I stole it one from my older sister. February of 2011 my sister Delsa developed her own version of General Mills' Turtle Chex Mix. In her own words:
I love the turtle chex mix you can buy at the store, but it's expensive. So today I created my own recipe (pretty similar). I made it in a small batch,I think, but these are the approximate proportions that I used. Be warned, it is addicting, but delicious.
I have been making it for parties and for family ever since, but have made a couple changes to adapt it to my tastes. It's been a long time since I had the "official" version, but this one is tasty enough that I don't miss it at all.
