While I could eat apple-flavored desserts all year long, nothing is better on a chilly night than a warm, cinnamon apple dessert! But this apple crisp recipe is not your average fruit dessert; it is made in individual serving sizes and can be done in the microwave! So whenever that apple crisp craving hits, you can make this easy dessert recipe in just minutes!

I have had fun coming up with new easy microwave mug cake recipes, but have been craving an apple version and knew I had to experiment a little until I found the perfect recipe. After a few tries, I have perfected these Mug Apple Crisps and love how they are like a little cup of fall, in one single serving!


  • Apple Filling – Peeled and sliced apples, melted butter, cinnamon, brown sugar, and flour.
  • Crisp Topping – Softened butter (not melted), flour, old-fashioned oats, brown sugar, and cinnamon.

How to Make Microwave Apple Crisp in a Mug

  4. Serve warm, preferably with a scoop of vanilla ice cream!

Helpful Tips

  • Want to make this recipe in the oven? Layer in an oven-safe ramekin and bake in a 375℉ oven for 120-12 minutes.
  • Feel free to adjust the amount of cinnamon or brown sugar to your liking.
  • For the crisp topping, the butter should be room temperature but not melted.
  • For the apples, the butter should be melted.
  • Make sure to use old-fashioned oats, not quick cooking.
  • The best variety of apple for a microwave crisp is your favorite variety! Any type of apple will work for this recipe. I personally prefer more tart apples, like Honeycrisp.

Fall is the season of comfort food and apples, and that is one of my favorite combinations. This Mug Apple Crisp Recipe is the perfect end to any fall evening!

  1. My 12 year old is just never very hungry for breakfast before school. Today I put this apple crisp in front of him (yes, I know it’s supposed to be dessert!) and he gobbled it up. Thanks! It’s warm and delicious, contains fruit and oatmeal, and filled him up before he went out the door! (My husband loved it too.)

  2. I looove your recipes! Thank you for what you do!!

    What size ramekin would work best for this recipe…? Thank you.

    1. A 12-ounce. Keep in mind that the ramekin is short compared to the mug so the cook time might be slightly different.

  3. We love your recipes – and this mug recipe is wonderful. Thank you for sharing them with us Fellow Foodies!

    Could I make this with peaches?

    Thank you !

  4. IM OBSESSED WITH THIS RECIPE! Its so quick and easy and so delicous. I would add a bit more cinnamon though.

  5. IM OBSESSED WITH THIS REDIPE! Its so quick and easy and so delicous. I would add a bit more cinnamon though.

  6. I just made it and really liked it. I would make again. I agree with another comment regarding what size apple to use. I used a small one and I’m not sure if a larger one would have made it more juicy. It seemed a little dry but still good. Thank you!

  7. I wanted to love this but it took a lot of effort to make for something being popped into the microwave. Measurements were followed to a T but we were quite disappointed. My husband thought it tasted like cinnamon apple oatmeal from a pack and told me it was the most disappointing dessert I’ve made when I asked for an honest opinion. I will say there’s a chance it would have been better had I used Granny Smith apples but I just used what I had on hand. The recipe was easy to follow and I appreciated that. The oatmeal was still very very crunchy after the 3 minutes and I used quick oats (expected a crisp but not raw oat taste). If you are trying this, maybe decrease the brown sugar a smidge.

    1. Hi A – The biggest issue I can see from your comment is that you used “Quick Oats” when the recipe calls for “Old Fashioned Oats.” There is quite a difference and the result would leave your topping the texture of oatmeal.

      1. Delishious! I used brown sugar substitute instead, as I have been experimenting with which recipes I can use with it (works well in a cake n a cup too) and it turned out amazing! It wasn’t exactly crunchy but if I wanted in the future I could make a crunchy topping. Was very nice with cream as well 🙂

  8. This review is in agreement with Corinne’s. Haven’t made yet but recipe seems super easy, simple ingredients, clear instructions. Thanks.

  9. I made this today and it was so easy and quick and I loved the simple ingredient list. I added walnuts to the apple mixture and then also of a nice scoop of vanilla ice cream when it was hot from the microwave. This is a terrific recipe and I will definitely make it again when I’m craving a delicious apple crisp. I ate the whole thing, but it makes enough for a small dessert for 2 people, especially if you add the ice cream. Really a great and easy recipe!

  10. I made with a nectarine. I didn’t have apples. It was really good.

    I will tweak the recipe as I don’t like anything really sweet. But I definitely will make again this summer with the nectarines and keep the apples for the fall. I think I’ll also add apples and walnuts.

  11. This was super yummy! Took a little bit longer than the typical 1 minute mug cakes I’m used to, but I really enjoyed it and would make it again 🙂 Only constructive criticism is that it would be great if you specified whether it was a small or large apple, because they’re so different!

  12. The recipe rating is based on ingredients, ease of preparation and clear instructions, as I have not made it yet. Just wanted to say I have spent half an hour wading through other people’s websites with similar recipes just trying to even FIND the recipe, just to be distracted by ads, links, landing pages, videos with no captions and never getting an actual recipe. Yes, everyone has ads these days but you do provide a recipe that was worth searching for. That’s what makes people come back. Thanks!

  13. This was really good! I like that it was one serving and I did not have to make a huge pan to satisfy my sweet tooth. Thank you for sharing!
