I like peanut butter.
It tastes good in a sandwich either with or without jelly. It also pairs well with apples, bananas, carrots, and celery.
I enjoy baking and occasionally bake those classic peanut butter cookies with the crisscross pattern on top. Then, during Christmastime, one of the various cookies I make includes peanut blossoms. Speaking of Christmas, though more of a candy, I also make chocolate peanut butter balls (or buckeyes, depending on where you're from) which are essentially homemade Reese's Cups but in ball form. Mix peanut butter with a few other ingredients, roll into balls, chill, melt some chocolate with a double broiler, dip them in the melted chocolate, let them sit and then enjoy. Delightful.
That of course leads me to Reese's Cups, which are one of my favorite candies. I don't eat candy outside of Easter or Halloween, but they're great.
Never tried a peanut butter and banana smoothie, but now having seen it mentioned in the thread, I'm going to try making one sometime soon.
