01 - In a mixing bowl, beat the softened cream cheese with an electric mixer until completely smooth and free of lumps. Add the granulated sugar, vanilla extract, and lemon zest, then mix on medium speed until well combined and creamy.
02 - In a separate chilled bowl, whip the heavy cream to soft peaks. Gently fold the whipped cream into the cream cheese mixture in two additions, using a spatula to maintain a light, airy texture.
03 - Divide the cheesecake filling evenly among the six flour tortillas. Spread each portion in a log shape along the center of each tortilla, leaving about one inch of space at the edges.
04 - Fold in both sides of each tortilla toward the center, then roll up tightly from the bottom to fully enclose the filling. Place each chimichanga seam-side down to hold its shape.
05 - Pour vegetable oil into a deep skillet or frying pan to a depth of about 1/2 inch and heat to 350°F (175°C). Carefully place the chimichangas seam-side down in the hot oil and fry for 1 to 2 minutes per side until golden brown and crispy. Transfer to a plate lined with paper towels to drain excess oil.
06 - While the chimichangas are still warm, combine the granulated sugar and ground cinnamon in a shallow dish. Roll each chimichanga through the cinnamon sugar mixture, turning to coat all sides evenly.
07 - Serve the chimichangas immediately while warm and crispy, accompanied by fresh berries, chocolate sauce, or whipped cream as desired.
