Preheat oven to 350°F. Grease and flour a bundt cake pan. In a large mixing bowl, cream together butter and sugar until light and fluffy, about 5 minutes. Beat in eggs, one at a time, until well combined. Add pumpkin and pumpkin pie spice; mix. Gradually add in House-Autry Buttermilk Biscuit Mix alternately with milk, until well mixed.
Spoon batter into prepared pan. Bake 1 hour or until a toothpick inserted in the center comes out clean. Cool 20 minutes before removing from pan. Sprinkle with powdered sugar and serve.
