I found a couple never-opened packages of cake and icing (still in the original bag and the packages inside) and I am wondering if they are still good. They are probably at least 3 years old. I read somewhere they are non-perishable and there is no expiration date on them. I used to love those cakes, so I'm wondering if its still okay to eat.

And, is there a way to make it in the microwave or a real oven? I don't feel like pulling out my old easy-bake oven.

So I put the cake in a muffin tin and its in the oven right now... I'll let you know if I die.
