Finally a gluten free mix that tastes great! I have used this mix over and over and I have never been disappointed. It works just the way the regular mix works and it has opened up a whole new world for me. I thought I would never be able to find a mix that I like, but this one I love. I am excited about trying all the fun things I can do with it. Even cookies!

These brownies bake up very nicely.  I would call their consistency "cake like".  However my husband called them Healthy Brownies.  He said he could taste the flax seed.  I tend to agree.  In my opinion, if I'm going to eat chocolate, I don't want it to have that "healthy" taste.  On the other hand I love the Blueberry Muffins that Hodgson Mill makes.
