Beat the butter, honey and pumpkin pie spice in a large bowl with an electric mixer on medium-high speed until thoroughly blended. Use a spatula to transfer the butter onto a large piece of waxed paper or plastic wrap. Use the sides of the paper or wrap to roll the butter into a baton shape. Twist the ends and place in the refrigerator until firm. Serve with warm pumpkin muffins or pumpkin bread. Keeps for 5 days in the refrigerator and up to 6 months in the freezer.
