Here is a link for eggless baking....
Their blueberry muffins looked very delicious!
Of course, the recipes are not gluten free, but that can be changed quite easily. I am not always exact, but the basic formula I use is: 2/3 rice flour to 1/3 starch, adding 1 tsp guar gum for every 2 cups of flour. Here is an example:
If a recipe calls for 4 cups of flour, I would substitute 2.5 cups of rice flour, 1.5 cups of starch (tapioca or potato) and 2 tsp guar gum.
I substitute water for milk in most baking recipes. If I feel I need to use milk, I use coconut milk which I usually dilute with water.
