In a large bowl using a handheld mixer or stand mixer fitted with a paddle attachment, beat the butter for 1 minute on medium speed until completely smooth and creamy. Beat in the remaining ingredients, starting with only ¼ teaspoon of salt. Beat on medium speed until completely smooth. Scrape down the sides of the bowl with a silicone spatula as needed. Taste. Add more salt (up to ¼ teaspoon) if desired.
Serve with a drizzle of honey and/or a sprinkle of sea salt. Cover leftovers tightly and store in the refrigerator for up to a week or so.
