01 - In a mixing bowl, beat the softened cream cheese, granulated sugar, vanilla extract, egg yolk, and salt together using an electric mixer or whisk until the mixture is completely smooth and creamy with no lumps remaining.
02 - Lay one egg roll wrapper flat on a clean work surface with one corner pointing toward you. Place approximately 1 1/2 tablespoons of the cheesecake filling in the center of the wrapper.
03 - Fold the bottom corner up and over the filling, then fold both side corners inward. Roll the wrapper tightly away from you, sealing the top corner with a dab of water. Repeat this process with the remaining wrappers and filling.
04 - Pour vegetable oil into a deep pan or heavy-bottomed pot to a depth of about 2 inches. Heat the oil over medium-high heat until it reaches 350°F. Use a thermometer to monitor the temperature for consistent results.
05 - Carefully lower the egg rolls into the hot oil in small batches of 3 to 4, turning them occasionally with a slotted spoon. Fry until the wrappers turn golden brown and become crispy, about 2 to 3 minutes per batch. Transfer each finished batch to a plate lined with paper towels to drain excess oil.
06 - Dust the warm egg rolls generously with powdered sugar. Serve immediately alongside chocolate or strawberry dipping sauce. For an elevated presentation, pair with whipped cream or fresh berries.
