Kerry -- I own and use two different kinds of ovens:

The bakepacker --   (You need to Login or Register and

The "Old Scout Reflector Oven"

The bakepacker is easier, in that it relies on a stove for heat.  I think it was developed in Sweden, for use by the military.  If you're not going to do much base-camping, I'd go with the backpacker.  You bake in oven bags, which have their limitations.  But I've enjoyed using it for muffins.

The Old Scout Reflector oven uses a campfire for heat. It is a lot of fun, and you can bake anything in it.  I pack along a 9-inch round baking pan.  Takes longer to set up, heavier, but good fun.
