Here's another online shop where you can get dairy-free, egg-free, nut free cake and cookie mixes: the Cherrybrook Kitchen.

The mixes were formulated by Patsy who developed food allergies as an adult in 2000. Thanks to her efforts, you can now bake desserts and treats for your food allergic family and friends without having to scour the city for alternative ingredients. Not only are they safe, they're also time-savers and convenient. Currently, Cherrybrook's Kitchen line of products includes mixes for cakes, brownies, cookies, pancakes, muffins and frosting. They also have a wheat/gluten free line.
The Cherrybrook Kitchen baking mixes can be found in a wide variety of stores throughout the country. Use their online store locator to find one near you!
