Which bowl muffin version have you been trying? I've only made superaunt's pancake bowl muffin version:

1/4 cup atkin bake mix
1/4 cup flax meal
1/2 cup mixture of sf vanilla syrup, heavy cream, water, sf maple syrup



...and it doesn't seem at all like an omelet texture to me . I've made it using Atkins bake mix and I also just made it using Carbquick (which I finally ordered and it came last night!) I make up half of my liquid mixture with heavy cream and the remainder with water and a just a little bit of the vanilla syrup and sf maple syrup.
