Put the room temperature butter into a large bowl or mixing dish.
Add in the measured honey - it should be room temp - not cold - or hot.
Run mixer on slow stir speed for just a few seconds to combing the ingredients.
Dump in the measured ground cinnamon (and a few drops of vanilla extract if you wish).
Mix all ingredients on slow speed until well combined. Then, jar up your cinnamon honey butter in an air tight container.
Notes
*Do not whip the mixture too long or the generated heat will cause the butter to melt**If you want a sweeter spread - double the amount of honey in the recipe.
