Dice enough strawberries to fill 1 cup. Chop extra strawberries to garnish.
In a large mixing bowl, combine one 250g block of room temperature cream cheese with 1 cup of sour cream. Add 1 tbsp of vanilla extract and 1/3 cup of sugar. Mix on medium-high speed until it has a nice creamy consistency.
Into the bowl, add diced strawberries, and fold evenly throughout the cream cheese.
Place the tortillas in the microwave for 35 seconds. This will make the tortillas easier to fold.
To fold the chimichangas, place two spoonfuls close to the middle of the tortilla to allow easy folding. Fold over the left and right sides first, so they almost meet in the middle. Then fold over the bottom. Hold on to the ends and roll until you have the shape of a small burrito.
Grease your air fryer with cooking spray and preheat to 200°C (400°F) for 3 minutes.
Lightly spray olive oil onto each chimichanga and place them seam side down into the air fryer, and cook for 8-10 minutes at 200°C (400°F). Leave space around each chimichanga to allow even cooking.
While the chimichangas are cooking, begin preparing the topping by combining 1/3 cup of sugar to 1 tbsp of cinnamon in a shallow bowl and mix.
When the chimichangas are light brown in colour, remove them from the air fryer and lightly brush melted butter on them. Begin rolling each one in the sugar and cinnamon topping. This will help the topping to stick to the chimichangas.
Place extra chopped strawberries on top, together with whipped cream and serve immediately.
