We were inspired by the microwavable chocolate mug cake that we've modified the recipe and adapted it to solar cooking. We really like the idea of using a mug to mix the ingredients in and then baking right in it.
It definitely won't be a 2 to 5 minute mug cake, but the texture & flavor is worth the wait.
Unsweetened cocoa powder
1⁄8 Large, whisked
1. Arrange a solar cooker with a stoneware/ceramic cup in a triple bowl and placed on a reflector.
2. Combine the all the ingredients in the cup and place it in the sun with an outside temperature of 51 degrees Fahrenheit or more.
3. Cook for 3 hours checking with a tooth pick if its done or not.
4. Unmold it on a plate and serve with whipped cream on the side.
