01 - In a mixing bowl, beat the softened cream cheese and granulated sugar with an electric mixer until completely smooth and creamy, scraping down the sides as needed.
02 - Pour in the heavy cream and vanilla extract, then continue mixing on medium speed until the filling becomes light, fluffy, and well combined.
03 - Lay a flour tortilla flat on a clean work surface. Spread approximately 3 tablespoons of the cheesecake filling across the lower third, leaving a ¾ inch border on all edges.
04 - Fold in both sides of the tortilla toward the center, then roll it up tightly from the bottom like a burrito, fully enclosing the filling. Repeat with the remaining tortillas and filling.
05 - Pour vegetable oil into a deep skillet or heavy-bottomed saucepan to a depth of about 1 inch. Heat over medium heat until the oil reaches 350°F, checking with a thermometer.
06 - Carefully place the chimichangas into the hot oil in batches, seam side down first. Fry for 2 to 3 minutes per side until deeply golden brown and crisp all over.
07 - Using tongs or a slotted spoon, transfer the fried chimichangas to a plate lined with paper towels and let drain briefly.
08 - Combine the remaining ¼ cup granulated sugar and ground cinnamon in a shallow dish. Brush each warm chimichanga generously with melted butter, then roll it in the cinnamon sugar mixture until evenly coated on all sides.
09 - Serve the chimichangas warm, optionally garnished with fresh berries and a drizzle of chocolate or caramel sauce.
