Preheat the oven to 350°F. Split the Chinese doughnut in half lengthwise, creating two thinner sticks. Place them on a baking tray and warm them in the oven for about 3-4 minutes. The goal is to heat them through without allowing them to brown. Remove from the oven and let them cool slightly.

While the doughnuts are warming, prepare the rice noodle rolls. Place them on a microwave-safe plate, covering them with a slightly damp paper towel to prevent them from drying out. Microwave in short intervals, checking after each one to ensure they don’t overheat. Once they become soft, warm, and pliable—typically within 1-2 minutes—they're ready to use.

Gently unroll a sheet of rice noodle and place a warm Chinese doughnut stick along one edge. Carefully roll it up, ensuring a snug wrap around the crispy doughnut. Repeat the process with the remaining rice noodle rolls and doughnut sticks.

Using a sharp knife, slice the rolls into bite-sized pieces. Arrange them on a serving plate and drizzle with sweet soy sauce. Sprinkle with toasted sesame seeds and sliced green onions.

Serve immediately with hoisin sauce and sesame paste on the side for dipping. If desired, add a touch of chili oil for an extra kick of heat. Enjoy while fresh!
