Gather your ingredients on the countertop.

Ensure your butter is softened to room temperature.

In a mixing bowl, add the softened butter. Use a hand mixer or whisk to beat the butter until light and fluffy.

Pour in the pure maple syrup while mixing.

If using sea salt, add it now and mix until fully combined.

Take a small spoonful to taste the butter. Adjust sweetness or salt if necessary.

Scrape the maple butter into a clean jar.

Let the butter chill in the refrigerator for at least 30 minutes.
