In a mixing bowl, combine your berries, half of the granulated sugar, cornstarch, vanilla extract, lemon juice, and cinnamon (if using). Toss gently until coated and let sit for 10 minutes.
Lay out a sheet of phyllo dough on a clean, dry surface. Brush it lightly with melted butter. Place another sheet on top and repeat the buttering process, using at least 4-5 layers.
Spoon the berry mixture onto the lower third of the phyllo, leaving about an inch from the edges. Don't overfill.
Carefully fold the sides over the filling and start rolling from the bottom up, tucking in the ends.
Once rolled, brush the top with remaining melted butter and sprinkle with sugar.
Preheat the air fryer to 350°F (175°C). Place the strudel in the basket and cook for about 15-18 minutes until golden brown.
Remove from air fryer, cool slightly, and dust with powdered sugar before slicing.
