Belgian Waffle

I am trying to duplicate the Belgian Waffles you get in many restaurants. I know that many of them use a commercial frozen product. I know that others use a commercial mix. I have purchased all the commercial mixes available and also the mixes in the supermarket. To us, they all taste the same. Rather, they are tasteless. None of them have that unique taste I love in the restaurants. I have added Malt. I have added oil. I am going to add vanilla tomorrow morning. Does anybody have any secret additives to add to a commercial mix. Need some help here.

Thanks,
Bob
