Cookies in the Sun Oven

I've borrowed a Sun Oven from a sweet friend, and since it's been sunny, I've been out experimenting with it a bit. I got it out Monday, intending to cook some bread in it since I was baking bread anyway, but it had never been out of the box, and the instructions say to let it heat up and then cool down and wash the interior before baking in it (you know, to burn off the "new" fumes), so that's how Monday's baking went--all the bread just went in the regular oven.

Tuesday was nice and sunny, so I busted the sun oven back out to bake some cookies. Here it is all set up in my yard:
After 20 or so minutes, it had heated up to about 310 degrees. Really. All you skeptics out there that think it would take two hours to heat up a solar oven, it really did heat up in 20 minutes. Here's the thermometer:
And just for good measure, here's a photo of the back of the sun oven with the height adjustment leg to enable you to aim it right at the sun. EASY.
I made my husband's favorite oatmeal cookies and put a pan of them in the oven. The cooking chamber isn't extremely large. I used a smallish pan instead of my regular cookie sheets.
This cookie recipe is 350 for 10 minutes, so I checked at 10 minutes and the cookies weren't quite done (of course, since the heat level was lower than 350).
Here's how we looked at 15 minutes. Done. Actually a little overdone--they were a bit dry. Not burned, just a bit dry. I pulled the second batch out a little sooner with better results.
That's steam coming out the top of the door when I opened it. Yep, it gets that hot in the oven.
The cookies were delicious, and cooking in the sun oven was easy. I'm definitely sold. I'll be trying something else this week before I have to give the oven back. :)
