I am not a real big peanut butter person - but I use both for baking - just depends on what I am making. I may even have a PBJ once or twice a year with either.
Did you ever have a peanut butter and scrambled egg sandwich? These are awesome. Yeah, it sounds nutty but these are great breakfast sandwiches.
Here's how to make one Peanut Butter and Scrambled Egg Sandwich:
Toast some bread, I like whole wheat bread myself, and then spread with peanut butter, chunky or smooth. Then make a scrambled egg like for an omelet, if you know what I mean. The finished egg should be like a pancake. Place the hot cooked egg on the peanut butter, and then top with the other piece of toast. Cut in half and serve. The heat of the egg will change the peanut butter and it will be gooey. You have to try this to be a believer

That sounds really gross, but a lot of people think that Peanut Butter and pickle sandwich is gross too....but I like those. Maybe I'll have to try this sometime.
Man, I love that! I like to take a knife and load it up with peanut butter, then put it on my banana. Take a bite, add more peanut butter, repeat process, enjoy. :p
