Yeah, the recipe section is very confusing... it doesn't "go" with the rest of the book.
About the Atkins Bake mix - it is not made anymore. I belong to the Atkins site, and received an email survery question not too long ago, asking if there would be an interest in them bringing it back. I don't know what they decided to do about it.
The alternative that I know of is called CarbQuick and I bought some online.
Ingredients: Carbolose flour (enzyme enriched wheat, vital wheat gluten, wheat fiber, high-protein patent wheat flour, vegetable fiber, canola oil, salt, dextrose, emulsifiers, enzymes, ascorbic acid, sucralose, calcium propionate), palm and palm-kernel oil, buttermilk powder, baking powder, egg white powder, lecithin, salt, natural flavors.
Since it contains wheat, it can introduced in Rung 9 (grains). It does have dextrose in it, but apparently a very small amount... serving size is 1/3 cup, and it list 0g sugar in the nutrition facts.
There are many who rave about it, but I wasn't impressed. There was a recipe for brownies that I tried. Even though it was kinda gross, I overate it anyway.

Even in Maintenance, I have to avoid that kind of stuff... control issues with grains.
