I have used the butter and like it, but it is not very spreadable. I switched to I Can't Believe It's Not Butter Light. I did try the Smart Balance peanut butter. I found that it wasn't nearly as flavorful as regular peanut butter. The only way I could eat it was to add a touch of splenda. The peanut butter I have found that I really like is the Jif Reduced Fat Crunchy. I have to be careful with it, though.. I found out that peanut butter is kind of a trigger food for me - If I eat even a little taste I want a peanut butter sandwich.. and then another.. and then another..
I wish I could banish it from my house, but my daughter loves it. I have not tried the cooking spray yet. I will have to look for it. I use extra virgin olive oil, too.
