Ingredients in Apple Crisp in a Mug
To make this delicious dessert, you'll need:
For the Stewed Apple
- Apple (green is best, but red will work too): green apples have the right tartness and texture to stay solid during cooking and also give you that delicious intense apple flavour. Red apples are much softer and sweeter, but will still work.
- Brown sugar: gives you the perfect caramelised flavour.
- Can I use white sugar? I don't recommend white sugar as it will not dissolve quickly enough and you will have a grainy stewed apple.
- Ground cinnamon: make sure your ground cinnamon is fresh and in date for the best flavour.
For the Crisp
- Melted butter: salted or unsalted butter is fine for this recipe.
- Brown sugar
- Plain flour / all-purpose flour
- Rolled oats / old-fashioned oats: make sure you are using whole rolled (old-fashioned) oats, NOT quick oats.

Frequently Asked Questions
Can I use white sugar instead of brown sugar?
Brown sugar gives the apples a rich caramel flavour and helps keep the topping crumbly. If you use the white sugar, note that it may taste gritty.
Can I use salted or unsalted butter?
Yes, either is fine for this recipe.
Why are my apples still firm?
This recipe is based on an 1100 watt microwave. If you have a weaker microwave, you may need to cook the apple crisp for longer than 2 minutes. Alternatively, if you have a stronger microwave, you may need to reduce the cooking time by 10 or more seconds.
Why should I use green apples in apple crisp?
Green apples are often used in apple crisp because of their firm texture and tart flavor. They hold their shape well when cooked and provide a nice balance of sweetness and acidity to the dish.
Green apples are also rich in pectin, which is a natural thickener. This means that when green apples are cooked, they release pectin that helps to thicken the fruit filling and give it a nice texture.

Storage & Substitutions:
