This was very good. I modified it a little...I couldn't find the corn starch so I omitted it and the water that it was dissolved in. Also, I only used 1 cup of water and I used 1 c of brown sugar. I guess I like it sweet.
I made this for DD today. She liked it and would have liked it even more if it was less sweet. Next time I'll try it with natural, unsweetened peanut butter. Thanks for posting.
