Frequently asked questions
+ − Can I make this without a microwave?
Yes! You can bake it in a small oven-safe ramekin at 375°F for about 15-20 minutes until the topping is golden and the apples are tender.
+ − What size mug should I use?
Use a microwave-safe mug that holds at least 12-16 ounces to prevent overflow during cooking. A wide-mouth mug works best for even cooking and easier eating.
+ − Can I double this recipe?
Absolutely! You can make it in two separate mugs or use a larger microwave-safe bowl. Adjust cooking times accordingly, adding 30-60 seconds as needed.
+ − Why did my apples turn out too soft?
This usually happens if the apple slices are cut too thick or if you re using a softer apple variety. Try using firmer apples and cutting them thinner next time.
+ − Can I prepare this ahead of time?
While best served fresh, you can prep the ingredients and assemble everything in the mug, then refrigerate for a few hours before microwaving. Add an extra 15-20 seconds to the cooking time if starting from cold.

Instructions
- 1
In a small bowl, combine softened butter and white sugar using your fingers to mix. Add flour, oats, one pinch of cinnamon, and salt. Continue mixing with your fingers until the mixture becomes crumbly and resembles coarse breadcrumbs.
- 2
Lightly grease a microwave-safe mug with butter or cooking spray. Press half of the oat crumble mixture into the bottom of the mug to form a crust layer.
- 3
Microwave the crust on high power for 30 seconds to set it slightly.
- 4
Layer the thinly sliced apple pieces over the crust. Sprinkle with brown sugar and the remaining pinch of cinnamon. Add water and gently mix the apple mixture without disturbing the bottom crust. Top with the remaining crumble mixture.
- 5
Microwave on 60% power for 1 minute and 50 seconds. Let cool for about 1 minute before serving to allow the filling to set and prevent burns.
