01 - Beat the cream cheese, sugar, vanilla extract, and sour cream in a medium bowl until completely smooth and creamy. Ensure no lumps remain for the best texture.
02 - Lay out all tortillas on a clean surface. Spoon approximately 2 tablespoons of cheesecake filling onto the lower third of each tortilla. Add 1 tablespoon of diced berries if desired. Fold in both sides and roll tightly from bottom to top, securing with toothpicks if needed to prevent unrolling during frying.
03 - Pour vegetable oil into a deep skillet or saucepan to a depth of 2 inches. Heat over medium-high heat until the temperature reaches 350°F. Use a kitchen thermometer to ensure proper oil temperature for optimal frying results.
04 - Carefully place 2-3 chimichangas in the hot oil, seam side down. Fry for 2-3 minutes per side until golden brown and crispy all over. Remove with a slotted spoon and transfer to paper towels to drain excess oil. Repeat in batches until all chimichangas are fried.
05 - While the chimichangas are still warm, brush each one generously with melted butter. This helps the cinnamon sugar adhere and adds rich flavor.
06 - Combine granulated sugar and ground cinnamon in a shallow dish, mixing thoroughly. Roll each buttered chimichanga in the mixture, pressing gently to ensure even coating on all sides.
07 - Serve the chimichangas immediately while warm and crispy. Optionally garnish with whipped cream, fresh berries, or drizzle with chocolate sauce for an extra indulgent presentation.
