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 in a diamond orientation. 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. Fold in both side corners toward the center, then continue rolling tightly upward. Lightly brush the top corner with water and press to seal the edge securely. Repeat with all remaining wrappers and filling.
04 - Pour vegetable oil into a deep heavy-bottomed pan or fryer to a depth of 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 at a time, turning occasionally with a slotted spoon. Fry until the wrappers are golden brown and crispy, approximately 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. Optionally garnish with whipped cream or fresh berries.
