In a bowl, add butter and salt. Using a hand mixer with the whisk attachment, whisk butter at low to medium speed until smooth and creamy.
Add honey and continue whisking until completely incorporated, smooth, and fluffy.
Serve immediately, or store in the refrigerator until ready to serve. Allow refrigerated butter to come to room temperature for 30 minutes for a spreadable consistency.
Notes
Honey butter will last for 1 month (or more) in a tightly sealed container in the refrigerator. Honey butter can also be frozen for up to three months.
Allow refrigerated honey butter to come to room temperature for 30 minutes before serving. It should maintain its whipped consistency, but can be rewhipped for a few seconds if needed.
Optional flavor additions: ½ teaspoon vanilla extract, 1 teaspoon ground cinnamon, or 1 teaspoon of lemon/orange zest.
