Step 1

Preheat the air fryer to 360 degrees F (180 degrees C).

Step 2

Combine pears, lemon juice, and 1/4 teaspoon cinnamon in a medium bowl. Toss to coat, then divide the mixture between 2 ramekins.

Step 3

Combine oats, flour, brown sugar, and remaining 1/2 teaspoon cinnamon in a small bowl. Mix in softened butter using a fork until mixture is crumbly. Sprinkle over the pears.

Step 4

Place the ramekins in the air fryer basket and cook until the pears are soft and bubbling, 18 to 20 minutes.
