Canyon Bakehouse Gluten Free Hamburger Buns are a new product at one of my local grocery stores (Stop&Shop/Giant). You can also buy them direct from Canyon. Hubby is a big fan of the taste and texture of these over a bunch of other buns we have tried. They are light-brown, unsurprising given that Brown Rice Flour is the top ingredient (also features Tapioca, Sorghum, Millet and Potato), have a texture close to that of wheat bread, and more taste than a lot of gluten-free products.
They are certified GF. They are also dairy, nut and soy free as well, if those are issues for you (but do contain eggs).
The only downside seems to be that they can get a bit squished in the freezing process (or more likely transfer), so it was hard to cut one or two of them and use them for an actual hamburger because the bottom was mangled up. But a definite thumbs up. They are now a repeat buy.
