This easy apple crisp in a mug is ready in minutes! Top it with vanilla ice cream and dig into a cozy apple dessert without even turning your oven on.
Cook the apples. Place diced apples in your mug. Add the water, sugar, and cinnamon. Give them a quick stir to combine. Microwave for 2 minutes, pausing halfway through to stir the apples.
You want the apples to soften so depending on your microwave strength you may need closer 3 minutes. You can add an extra splash of water if the apples are too dry at the 2-minute mark. Once the apples are softened, set aside.
Make the topping. In a bowl combine the oats, flour, brown sugar, salt and melted butter. Stir well until the oats and flour have been incorporated.
Finish cooking. Spoon topping over the microwaved apples. Microwave for 1 minute 30 seconds to 2 minutes, until the oats have softened and cooked.
Cool and serve. Allow to cool for 5 minutes, it will be HOT. Top with a scoop of ice cream and dig in.
*Use two apples if you want a lot of apple filling
