01 - Combine cinnamon, nutmeg, ginger, cloves, and allspice in a small bowl. Reserve mixture for multiple uses.
02 - Mix granulated sugar with 2 teaspoons of the prepared pumpkin spice blend in a wide, shallow bowl.
03 - Separate biscuits individually. Press a 1-inch round cutter or bottle cap through the center of each biscuit to create donut shape. Reserve cut centers for donut holes.
04 - Pour vegetable oil into a heavy-bottomed pot. Heat to 350°F, maintaining temperature throughout frying process.
05 - Carefully lower 3-4 donuts into hot oil. Fry 1-2 minutes per side until deep golden brown. Cook donut holes approximately 1 minute total.
06 - Transfer fried donuts to paper towel-lined tray using a slotted spoon. Allow to drain briefly while still warm.
07 - Immediately toss warm donuts in spiced sugar mixture, pressing gently to ensure even coating on all sides.
08 - Whisk powdered sugar, milk, vanilla, and remaining pumpkin spice until smooth. Drizzle over cooled donuts or dip tops for extra sweetness.
