Step by Step Instructions
It takes only 5 minutes to make a warm individual apple crisp in a mug!
- Chop Apple - Peel and chop up the apple into small pieces. The smaller the pieces, the more tender they will be. If you like your apples to have more of a bite, then cut them a little larger.
- Toss with Sugar and Spices - Add to microwave safe mug and toss with cinnamon, nutmeg, and brown sugar (if using).
- Make Crisp Topping - In a small bowl, melt the butter. Mix the melted butter with brown sugar, flour, oats, cinnamon, and nutmeg. Top the apples with the oat crumble mixture.
- Microwave - Microwave the mug for 2 - 2 ½ minutes. The apples should be tender and the crisp topping should be bubbling.
- Enjoy - Allow to cool for a few minutes and enjoy!
Frequently Asked Questions
Any standard size (8 ounces or larger) coffee mug works! This apple crisp will cook down as the apples cook, so it's okay if the recipe fills up to the brim of your mug. Unlike other mug cakes, this one does not rise and expand as it cooks. The most important piece is to use a mug that is microwave safe!
Because you eat the crisp right out of the mug, you do not need to grease. Although, if you want easier clean up you could spray with cooking spray before cooking. I do not grease and instead just soak the mug in some warm soapy water for a few minutes before cleaning to remove any cooked on bits.
This recipe is written for one apple crisp, but you can easily double it to make two! You can chop up two apples and divide between two mugs. You can do the same with the crumble topping - mix up a double batch and divide between the two mugs. It’s best to microwave them separately, though.
Equipment Needed:
- Microwave-Safe Mug - Use a standard size (8oz or larger) microwave safe mug. If you don't have a mug, you can use another microwave-safe dish to cook.
- Peeler - I like to peel the apple. If you don't have a peeler, you can carefully use a sharp knife to remove the apple skin or you can leave the skin on if you don't mind the texture.
Serving Ideas:
This recipe is perfect on its own! To take it up a notch, try topping it with a scoop of vanilla ice-cream or some fresh whipped cream.
Recipe Tips:
- Cook Time Varies - Microwaves have different strengths which will impact the cook time. I recommend you check the crisp after about 1.5 minutes then add more time, as needed. If you make it in a more shallow dish vs the mug, then it will also cook faster.
- Apple Pieces Size - If you want your apples to have more of a 'bite' then cut the pieces larger. If you want them super soft, then cut them smaller.
Other Microwave Mug Recipes:
- 3-Ingredient Nutella Mug Cake - Such an easy single serving chocolate treat.
- Hot Cocoa Mug Cake - Hot chocolate in cake form is a fun single serving dessert. Don’t forget the warm, gooey marshmallows on top.
- Molten Chocolate Cake - Super chocolatey and gooey in the middle.
- Mug Rice Krispie Treat - Just 3 ingredients and 1 minute in the microwave. A Microwave Mug Rice Krispie Treat is a favorite by both kids and adults
