Are you keeping the flaxseed powder refrigerated? If not, than that's probably the number one problem you need to fix if you want it to be edible. The oil in powdered or cracked flaxseed goes stale at room temperature within just a few days and it starts to smell disgusting. I don't understand why most stores don't refrigerate it. Refrigerating it makes a HUGE difference. Of course, if it's already stale, there's not much you can do.

As far as I know, most people eat flaxseed powder with hot cereal or bake it into baked goods. I never tried doing it myself, so I can't say for sure how it tastes, but I've had store-bought "fiber" baked goods with flaxseed and they tasted fine. I bought the powder for baking a few years ago but I through it out because it smelled so bad.

You could also try using very little of the flour and instead replacing most of your flaxseed dose with "cracked" flaxseed. Cracked flaxseed has a very mild taste for some reason. It's only when they powder it that the weird smell is fully released. You shouldn't use whole flaxseed because it doesn't get digested. It tends to pass right through you whole, bleck Of course you could buy it whole and then crack it yourself with a mallet or mortar and pestle or something.
