I often have spur of the moment baking ideas and get annoyed when a recipe calls for softened butter. Even when "gently" microwaved, I have a tendency to melt some of it. The best way around that is to pour boiling water in a microwave safe glass in order to heat it the glass. Pour the water out and flip it over the cold butter stick. It will be perfectly soft and ready to use in a couple minutes.
