  1. Can you use lactaid milk as I am lactose intolerant and do you need the almond butter- I am diabetic- would’ve to make this to satisfy my sweet tooth.

    1. Hi Joann, we have only made this recipe as listed so I can’t say for sure. Lactaid milk should work fine in this recipe but we have never attempted it without almond butter. Maybe another reader has some insight into that.

  2. Is the carb count for one serving or both? I am assuming both, but you know what they say about that! So thought I would asked.
