01 - In a mixing bowl, combine the softened cream cheese, granulated sugar, vanilla extract, egg yolk, and salt. Beat with 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. Place approximately 1½ tablespoons of the cheesecake filling in the center of the wrapper.
03 - Fold the bottom corner up and over the filling. Fold both side corners inward toward the center. Roll the wrapper tightly upward, sealing the top edge with a dab of water. Repeat with the remaining wrappers and filling.
04 - Pour vegetable oil into a deep pan or fryer to a depth of 2 inches. Heat the oil to 350°F over medium-high heat.
05 - Carefully lower the egg rolls into the hot oil in batches of 3 to 4, turning occasionally, until golden brown and crispy on all sides, approximately 2 to 3 minutes per batch. Transfer the fried rolls to a paper towel-lined plate to drain excess oil.
06 - Dust the warm egg rolls generously with powdered sugar. Serve immediately alongside chocolate or strawberry sauce for dipping.
