Combine all ingredients in a bowl. Using whisk attachment on mixer, blend until smooth and creamy, scraping down sides of bowl as needed.
Use a rubber spatula to pour mixture into the half pint jars. If you are worried that you will spill it, you can always use a large pastry bag (or zipper style storage bag), cut off tip and squeeze into the half pint jars.
*tip: Place the bag in a tall glass for support or have someone hold the bag while you are filling it.
