1. 1. Open the biscuit dough and separate each biscuit. Cut each biscuit into 4-6 bite-sized pieces. 2. In a shallow bowl, combine the 1/2 cup granulated sugar and 1 tablespoon cinnamon. Stir well. 3. Pour 3-4 cups oil into a large heavy-bottomed pot to a depth of about 2-3 inches. Heat over medium heat to 350-360°F (175-180°C). 4. Carefully drop a few dough pieces into the hot oil without overcrowding. Fry for 1-2 minutes per side until golden brown and puffed. Use a slotted spoon to flip and remove. 5. Drain on paper towels for about 30 seconds, then immediately toss in the cinnamon-sugar mixture until evenly coated. Set on a wire rack. Repeat with remaining dough. 6. For the glaze: In a medium bowl, whisk together softened cream cheese, powdered sugar, 1 tablespoon milk, and vanilla extract until smooth. Add more milk (up to 1 more tablespoon) if needed for drizzling consistency. 7. Drizzle the glaze generously over the warm donut bites. Serve warm or at room temperature.
