I made this recipe with teff flour instead of kamut flour and calculated the following (estimated) nutritional values for one serving (one twentieth of the full recipe): 158 calories; 17g fat; 20g carbohydrates; 3.5 g fiber; 3.7 g sugar; 3.5 g protein (healthbean.ca)
I've used teff flour in chocolate cake and chocolate chip cookies with wonderful results. (glutenfreeonashoestring.com)
I couldn't find teff flour in supermarkets near me so I bought it online which is of course easy enough. (carolinescooking.com)
