Just adding a comment here. I have seen this recipe before but it used a box of sugar-free vanilla pudding (the kind you cook) as well as the other ingredients. Perhaps an ingredient was omitted and that is why the other reviewers had problems.
I've made this, too. I agree with the bitter taste. I thought it was the combo of Splenda with the pumpkin, but don't really know for sure. I threw the whole thing out... Nobody in my family or at work liked it. Sorry, just didn't work for me.
I made this because I had some unflavored gelatin that I needed to use up, and I thought I would give it the benefit of the doubt, but it just did not turn out well for me either. Strangely bitter or with a weird tang or something. I cook with splenda all the time so I don't think that was the problem... maybe the gelatin, or not enough milk or spices? Sorry!
I'm always looking for good weight watchers recipes so I tried this one. I followed the directions exactly and it came out terrible. I only took one bite and it left a awful aftertaste in my mouth. Sorry Chef #290742.
