Prepare the Filling: In a mixing bowl, combine cream cheese, sour cream, green onion, garlic, soy sauce, sugar, and salt. Mix until smooth and well combined.
Assemble the Rolls: Lay a spring roll wrapper flat on a clean surface. Place a spoonful of the cream cheese mixture near one edge of the wrapper. Fold in the sides, then roll tightly, sealing the edge with a little water. Repeat for the remaining wrappers.
Bake the Rolls: Preheat the oven to 190°C (375°F). Place the rolls on a baking sheet lined with parchment paper. Brush lightly with sesame oil or olive oil. Bake for 12-15 minutes, flipping halfway through, until golden and crispy.
Serve and Enjoy: Let the rolls cool slightly before serving. Serve with sweet chili sauce, soy sauce, or honey for dipping.
