Place the softened butter into the bowl of a food processor; sprinkle with salt.
In a saucepan over medium high heat, bring the sugar, cream, and honey to a boil; cook one minute, stirring often.
Pour the hot honey butter mixture over the butter in the food processor; process until well combined. Add vanilla, then process once more until smooth.
Pour the honey butter spread into jars; let cool. Seal jars tightly with a lid. Store in refrigeration.
Honey butter spread will keep 6 weeks in the fridge and up to 6 months in the freezer. **If freezing, be sure to leave at least 1/2-inch head space when filling jars.
