Step-by-Step Instructions

Step 1: Prepare the Apple Base
Peel and dice the apple into small, even cubes. Keeping pieces uniform ensures even cooking in your single serve apple crisp. Place the apple pieces in a small bowl. Add granulated sugar, cinnamon, lemon juice, and cornstarch. Toss until evenly coated. The cornstarch thickens the juices during cooking so your single serve apple crisp does not become watery.
Transfer the mixture into a small oven safe ramekin or a microwave safe mug if preparing apple crisp in a cup.

Step 2: Make the Crisp Topping
In another bowl, combine rolled oats, flour, brown sugar, and salt. Add the cold butter cubes. Use your fingertips to rub the butter into the dry mixture until it resembles coarse crumbs. The texture should look slightly clumpy. This crumb structure is essential for a proper single serve apple crisp topping.
If you are familiar with how to make oatmeal in a mug or oatmeal cookie in a mug, the crumble texture is similar but slightly drier to achieve crispness.

Step 3: Assemble the Single Serve Apple Crisp
Sprinkle the crisp topping evenly over the apple mixture. Do not press it down. Keeping it loose allows steam from the apples to circulate and helps the topping cook properly.
At this stage, your single serve apple crisp is ready for baking or microwaving.

Step 4: Oven Baking Method
Preheat the oven to 180°C. Place the ramekin on a baking tray. Bake for 18 to 22 minutes until the topping turns golden and the apples bubble at the edges.
Remove carefully and allow to rest for 5 minutes. The filling thickens as it cools slightly.

Step 5: Microwave Method
If preparing apple crisp in a mug microwave style, place the assembled mug in the microwave. Cook on high for 1 minute. Check texture. Continue in 30 second intervals until apples are tender.
