01 - In a mixing bowl, beat the softened cream cheese until completely smooth. 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 uniform in texture.
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 while leaving a border for folding.
03 - Fold the sides of each tortilla inward toward the center, then roll tightly from the bottom up to fully enclose the filling. Secure with toothpicks if needed to prevent unrolling during frying.
04 - Pour vegetable oil to a depth of 2 inches into a deep skillet or heavy-bottomed pot. Heat over medium-high heat until the oil reaches 350°F. Use a cooking thermometer to monitor the temperature accurately.
05 - Carefully lower the chimichangas into the hot oil, working in batches to avoid overcrowding. Fry for 2 to 3 minutes per side until deeply golden brown and crisp on all surfaces.
06 - Using tongs, remove each chimichanga from the oil and immediately roll it in the cinnamon sugar mixture while still hot, pressing gently to ensure an even, generous coating on all sides.
07 - Transfer the coated chimichangas to a wire rack or paper towel-lined plate. Allow to cool for 3 to 5 minutes before serving so the filling sets slightly. Serve with whipped cream, chocolate sauce, or fresh berry coulis.
