Ready to create this delicious treat? Follow these simple steps:

1. In a medium bowl, combine the softened cream cheese, sugar, and vanilla extract. Mix until smooth and creamy.
2. Gently fold in the blueberries, ensuring they are evenly distributed throughout the cream cheese mixture.
3. Lay an egg roll wrapper on a clean surface, and place about 2 tablespoons of the blueberry cream cheese mixture in the center.
4. Fold the bottom corner of the wrapper over the filling, then fold in the sides and roll up tightly. Use a bit of water to seal the edges.
5. Heat about 1 inch of vegetable oil in a deep skillet over medium-high heat. Once hot, carefully place the egg rolls in the oil, a few at a time, and fry until golden brown on all sides, about 3-4 minutes.
6. Remove from oil and drain on paper towels. Allow them to cool slightly before serving.
7. Dust with powdered sugar before serving, if desired.

Pro tip: Make sure the oil is hot enough before adding the egg rolls, as this will ensure they turn out perfectly crispy.
