Combine butter, vanilla bean seeds, honey, powdered sugar and salt in the bowl of a stand mixer fitted with a paddle attachment. Beat on medium speed until smooth and fluffy, scraping down the bowl as needed.
If using as a spread, transfer to a bowl and use while soft. Otherwise, spoon onto parchment paper or plastic wrap and roll into a tight log. Refrigerate until firm.
Vanilla bean honey butter is a delicious spread for toast, waffles, pancakes, biscuits, scones, muffins and pound cake.
