I've not tried that specific oven but would suggest you look into JMOs or jello mold ovens.  I've had nothing but good results on can stoves, kitchen burner, and fire.  A couple of bucks at a thrift store.  The bigger the mold the better.  Did a fine cake at a recent camp.  Mostly pizza/calzones; cornbread for rice and beans, that kind of stuff.  Thinking about some yeast bread on a warm layover day.
