Air Fryer Apple Crisp with Oatmeal Streusel Topping

Preheat the air fryer oven to its highest temperature setting, which is 350 degrees Fahrenheit or 175 degrees Celsius.

In a large mixing bowl, merge sliced apples with brown sugar, softened butter, a hint of vanilla extract, ground cinnamon, ground nutmeg, and a pinch of salt. Use your hands or a spoon to thoroughly coat the apples with the mixture, ensuring they are evenly covered.

Spritz four small ramekin cups with non-stick cooking spray to prevent sticking. Distribute the apple mixture equally among all four ramekins, filling them about 3/4 of the way full. Cover the ramekins with aluminum foil and cook in the air fryer oven until the apples are tender, approximately 20 minutes.

Simultaneously, prepare a streusel topping in the same bowl by blending rolled oats, all-purpose flour, brown sugar, softened butter, ground cinnamon, and a pinch of salt. Use your fingers to mix the ingredients until they form a cohesive mixture. Place it in the refrigerator for later use.

Remove the ramekins from the air fryer oven and divide the streusel topping equally among all four cups. Place them back in the air fryer oven, this time without foil, and cook until the streusel is a golden brown color, requiring about 5 to 7 minutes.
