Melt butter in a pan. Add apples, brown sugar, lemon juice and cinnamon. Cook until soft and sweet, stirring often for even cooking.

Mix cornstarch and water in a small cup. Pour into apples. Cook again until thick and glossy. Remove from heat and let cool slightly.

Lay tortillas flat on a board. Place warm apple filling in a line near one edge. Do not overfill or rolling becomes messy.

Roll each tortilla tightly around filling. Keep seam side down so they stay closed. Work slowly to avoid tearing thin tortillas.

Brush outside of taquitos with melted butter. This helps them turn golden in the air fryer and hold cinnamon sugar well.

Set air fryer to 375 degrees Fahrenheit. Preheating gives even crisp texture and faster cooking with beautiful golden color outside.

Place taquitos in basket seam side down. Do not overcrowd to allow air flow. Cook until crisp and golden, turning once carefully.

Mix white sugar and cinnamon in a bowl. While taquitos are warm, roll them in mixture. Sugar sticks better when still hot.

Let taquitos cool a few minutes. Filling is very hot inside. Cooling makes them safer to eat and flavors settle nicely.

Serve with whipped cream or vanilla ice cream. A caramel drizzle also tastes amazing. Enjoy warm for best texture and flavor joy.
