Preheat the oven to 350 F. Separate the biscuit dough and cut out holes in each one. Place onto a large greased baking sheet.
Bake for 12-15 minutes. Place melted butter into a shallow dish. In another shallow dish, whisk together granulated sugar and pumpkin pie spice.
Roll each donut into the melted butter, then roll into the cinnamon sugar mixture.
