What do you mean bread withought the grains? Why do people keep referencing processed flour? What exactly does that even mean? What does OP mean?
OP means Opening Post, that means the topic you started, your question.
You have not explained why you made such a weird request however, and that would have really helped.
Part of the reason why everybody is puzzled is that you are asking for a very unhealthy thing, with random substitutions that don't make it any healthier and don't make much sense.
Are you asking for a soymilk biscuit because you are lactose intolerant? If not, milk would be healthier.
Normally people ask for it without regular grain flour because they are intolerant to gluten in grains. But that doesn't seem to be the reason either for you.
And why would you ask for it without sugar? You are aware that all starch is converted into sugar as you digest it, right? Normally people ask for ways to reduce calories, but you are asking for a biscuit which is already a very high calorie thing anyways...
So again, you should give more details about why you are asking your question and why you want it that particular way, because right now it makes no sense and it's difficult for people to give you advice even if they are all trying to be helpful to you.
If you don't like the milky/buttery/floury flavor of biscuits it seems easier to just eat something else than to try to make high-calorie but tasteless versions without milk, butter, flour etc.
My guess given your other post about removing all sugars is that your question might stem from an overly simplified concept of nutrition and diet and a desire to still eat your favorite biscuits with ingredients that you believe might be healthier but are not. I may be wrong on this but again without an explanation and more details fromyou that's the best guess anybody would come up with.
