I made the black bean brownies in P1, since they were listed as at P1 dessert. I couldn't find SF chocolate chips, but used a SF chocolate bar I found in the diabetic/special foods section of the grocery store, that I then cut up. I can say, however, that after eating them I was in agony (gas, bloating, etc.) and I blame it on the SF chocolate bar, since it contains malitol and malitol does have those side effects. Also, they set me off big time--I had 5 within about 18 hours (sleeping for about 10 of those hours.) I ended up putting any leftovers down the disposal. And, DH and DS were not impressed at all, and would not even eat one. So.........I know a lot of people seem to like them, but I wouldn't bother again.
Or, make them without the chocolate pieces.
Or, try the black bean chocolate cake (2 recipes.) It's a little lighter, and does not call for the chips. DH and DS did not like it, but I thought it was okay. Tastes heavily of Splenda.......good with the peanut butter-cream cheese frosting (the best part, I thought!)
