Sansie - I'm going to try it with the same amount of brownie mix. It's just 1 or 2 more calories than the Funfetti mix!
Tip: I portioned the entire box into the appropriate amounts and put each serving into its own baggie. That way I won't do a "whoops, I 'accidentally' dumped too mix mix into my yogurt; oh well!" Sometimes I have to be awfully clever in order to outsmart myself!
