Example Input: Hubby had to switch to gluten free because of gluten intolerance so we tried this and made pancakes. They were great and had sort of a corn bread texture to it. FYI: i made cobbler from an regular bisquick recipe (not gluten free) and the measurements do not transfer. The proportions are different with the gluten free mix so make sure you have the right recipe for what you're making.
