power in my experience, i.e. the bars stick together and hold their shape really well. otherwise peanut butter works well, as does almond butter.
‡i found that the earth balance spread was harder to stir into my dry stuff. i started adding the spread to my butter when i melt it in the microwave so that it melts and gets good and liquid-y and i can whisk all my wet things together really well and the stirring is much easier at the end.
