In a medium bowl, combine the softened butter and honey.
Add the salt, if using, and stir until well combined.
Transfer the honey butter to a serving dish. Serve immediately or store in an airtight container in the refrigerator.
Notes
Honey butter can be made ahead of time and stored in the refrigerator for up to two weeks. Let it sit at room temperature for about 15-20 minutes before serving to soften.
