For those with gluten allergies, this is great. The shortcakes, biscuits, pancakes taste much the same as with the regular Bisquick. My only problem with it is that it comes in such a small size. Would love for them to box it in larger sizes.

I have been making Belgian waffles using the Stonewall Kitchen Farmhouse Pancake and Waffle Mix for over three years.  My waffles are undoubtedly the best ever!!!  I like my waffles light and crisp - I can't stand a heavy soggy waffle. These just melt in your mouth.  I have made homemade waffles, but I have yet to find anything that can compare to this mix.
