In a mixing bowl, beat the softened cream cheese with an electric mixer or whisk until smooth.
Add the powdered sugar and vanilla extract to the cream cheese and mix until well combined.
In another small bowl, combine diced strawberries and lemon juice. Gently fold the strawberries into the cream cheese mixture.
Lay a tortilla flat on a clean surface. Spoon about 3 tablespoons of the strawberry cheesecake filling onto the center of the tortilla.
Fold the sides of the tortilla over the filling, then roll it up from the bottom to create a chimichanga. Repeat with the remaining tortillas and filling.
In a frying pan, heat the vegetable oil over medium heat. Once hot, carefully place the rolled chimichangas into the oil, seam side down.
Fry for about 2-3 minutes on each side or until they are golden brown and crispy. Use tongs to flip them carefully.
Once cooked, remove the chimichangas from the oil and place them on a plate lined with paper towels to drain excess oil.
While still warm, sprinkle the chimichangas with ground cinnamon if desired and serve with whipped cream and additional strawberries.
