Place the softened butter in a medium mixing bowl. Using a hand mixer or stand mixer fitted with the whisk attachment, beat the butter on medium-high speed for 2-3 minutes until it becomes pale and fluffy.
Add the powdered sugar, honey, cinnamon, vanilla extract, and salt to the bowl.
Start mixing on low speed to incorporate the dry ingredients without creating a mess, then increase to high speed.
Whip the mixture for another 2-3 minutes until it is light, airy, and completely smooth.
Serve immediately at room temperature, or transfer to an airtight container and refrigerate. If refrigerating, let it sit at room temperature for 15 minutes before serving to soften.
