Have you ever tried crock pot baking?

In, "A Year of Slow Cooking", blogger and cookbook author Stephanie O'Dea uses a crock pot to make gluten free recipes, including gluten free breads and cakes. We have more food allergens than simply gluten, which means if I try her recipes, I'll have to make adjustments for eggs or cow's milk or other allergens.

I've never baked breads or cake in the crock pot - not even before gluten free - have you?

This is one of the recipes I'm considering:

Bread is another:

What is your experience with allergen-free *baking* in a crock pot?
