01 - In a mixing bowl, beat the cream cheese until smooth and lump-free. Add granulated sugar and vanilla extract, mixing until creamy and well incorporated. Pour in the heavy cream and lemon juice, then beat until the mixture is light, fluffy, and holds soft peaks.
02 - Lay each flour tortilla flat on a clean work surface. Spoon approximately 2 to 3 tablespoons of the cheesecake filling onto the lower third of each tortilla, spreading it gently into an even layer.
03 - Fold both sides of each tortilla inward toward the center, then roll tightly from the bottom edge upward to fully encase the filling. Insert a toothpick to secure the seam if needed.
04 - Pour vegetable oil to a depth of 2 inches into a deep skillet or heavy-bottomed pot. Heat over medium-high to 350°F, using a cooking thermometer to monitor the temperature for consistent results.
05 - Carefully lower the chimichangas into the hot oil in small batches, frying for 2 to 3 minutes per side until the tortillas turn a deep golden brown and become crisp. Avoid overcrowding the pan.
06 - Using tongs, remove each chimichanga from the oil and immediately roll it in the cinnamon sugar mixture on a shallow plate, coating all sides evenly while still hot so the sugar adheres well.
07 - Transfer the coated chimichangas to a wire rack or paper towel-lined plate. Allow to cool for a few minutes before serving to let the filling set slightly.
