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

  1. Mix apples with melted butter, cinnamon, brown sugar, and flour.
  2. Combine oats, flour, brown sugar and cinnamon then use a fork to mix in the softened butter.
  3. Layer apples and crisp topping in a mug and microwave for 3 minutes.
  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!

    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.)

    1. Kristin says:

      You are so welcome Susan! Thank you for the awesome comment.

  2. Deanne says:

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

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

    1. Kristin Maxwell says:

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

  3. Deanne says:

    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 !

    1. Kristin Maxwell says:

      I think it would be delicious with peaches. I would suggest peeling them first.

  4. Mieke says:

    Holy microwave this tasted sooooo good!

      Thank you Neet!

  8. Cook4Ever says:

    Hi! his was amazing! Quite easy to make as well. I added 2tbles of chocolate chips and it worked amazingly!

  9. Amy says:

    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!

    1. Kristin says:

      You are so welcome Amy! Thank you for taking the time to share.

  10. Iris says:

    it is not showing me how to make it

    1. Kristin Maxwell says:

      I’m not sure what you mean. There are instructions in the recipe card at the end of the post.

  11. A says:

    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. Kristin Maxwell says:

      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. E.P says:

        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 🙂

    2. Cook4Ever says:

      It does taste a bit like oatmeal, but otherwise very good. Try adding some ginger and chocolate chips.

  12. maryann says:

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

    1. Kristin says:

      You are so welcome Maryann! Thanks for stopping by.

  13. Ozzie says:

    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!

    1. Kristin says:

      Awesome feedback Ozzie! Thanks for stopping by.

  14. Donna says:

    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.

    1. Kristin Maxwell says:

      That sounds so good!

  15. Melinda says:

    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!

  16. Corinne says:

    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!

    1. Kristin says:

      Thank you so much for stopping by Corinne! Love the feedback!

  17. Melissa says:

    Exactly what I was craving! Easy and quick as well. Thank you!!!

      Nice! You are so welcome Melissa! Thanks for stopping by.

    Absolutely delicious!

  19. Matt says:

    This. Was. Heaven. Especially licking the crumble mixing bowl

  20. Shamika Cole says:

    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!

    1. Kristin says:

      You are so welcome Shamika! Thanks for stopping by.

  21. Anonymous says:

    I made this and it was SO GOOD! Will make again. I pretty much followed the recipe but one thing I didn’t follow was the peeling of the apples part because i was to lazy (lol) Did send to a friend and she made it and loved it too! Thank you so much!

    1. Kristin says:

      You are so welcome Anonymous! Thanks for sharing the love.

  22. Micki says:

    I’ve made this a few times now and I absolutely love it! Perfect, for when that craving for something sweet hits! Give it a try x x

    1. Kristin says:

      Love the feedback Micki! Thanks for stopping by.

  23. kmnewbill says:

    I just made this as a snack and it’s amazing! The only thing I want to warn you about if you make this is let. it. cool. I let it cool for a minute and still burned my mouth. Other than that this recipe is amazing, it tastes great

    1. Kristin says:

      OUCH! Thank you for your feedback and thanks for stopping by.

  24. Julie says:

    I subbed almond flour for the flour and coconut oil for the butter and it was great! Only recommend using slightly less coconut oil if you choose to sub that, mine had a little too much. Overall very yummy and this will go in the quick dessert rotation for sure!

    1. Kristin says:

      Nice! (Awesome feedback) Thank you so much for stopping by Julie.

  25. Joanne M McConnell says:

    I made 2x servings, baked it in a 350-degree oven for 50 minutes. It is delicious and very easy. I also tried it in the microwave and it was good, but the oven-baked was much better. I sent the recipe to my sister who lives alone.

    1. Kristin says:

      Awesome feedback Joanne! Thank you so much for stopping by.

  26. Lena Zhu says:

    I made this today and it was so good. Usually, I would be skeptical because desserts are too sweet, and I am not a cinnamon lover, but this was quite perfect. Thanks!

    1. Kristin says:

      You are so welcome Lena! Awesome feedback, thanks for stopping by.

  27. Karen says:

    Would love to make this for company. Do you think I can make the topping ahead of time?

    1. Kristin Maxwell says:

      You could mix up the topping without the butter ahead of time, then add the butter right before cooking them.

  28. Christine says:

    Very nice! I wasn’t real happy about dirtying more than one bowl, but it was worth it – lol. Next time I will double the recipe for me and my 10 year old. I ate it with vanilla bean ice cream and it was out of this world! Thank you for such a great recipe!

    1. Kristin says:

      You are so welcome Christine! Thanks for stopping by.

  29. Rick says:

    Why thin sliced apples? Wouldn’t chunked or chopped apples work? (And maybe be easier to work with.)

    1. Kristin Maxwell says:

      Chopped apples would be too thick and wouldn’t cook in the short time in the microwave.

  30. katie says:

    when i tell you this was DELICIOUS!!!!!! if only i had ice cream ?

    1. Kristin says:

      Thank you Katie!

    This is DELICIOUS!! Perfect easy fall recipe

    1. Kristin says:

      Thank you Mia!

      1. jacinda says:

        If i double the recipe do i cook in microwave for 6 min?

        1. Kristin Maxwell says:

          If you want to double the recipe you should use two mugs.

  33. Jenni Campbell says:

    I am collecting ‘mug’ cake and pudding recipes to use when travelling in our caravan. Thank you for this recipe – Jenni in Australia

    1. Kristin Maxwell says:

      That’s a great idea – good luck to you!

  34. Heidi says:

    The point of a mug dessert is to not dirty up a bunch of extra dishes. Just smoosh it all together in the mug, it’s the flavor that counts!!!! Really love these mug desserts, it’s just me and my 13 yo so we don’t usually finish full size desserts

    1. Kristin Maxwell says:

      Yes you can definitely just do it that way, although you do want to mix the filling and topping separately. This is more of a way to avoid turning on your oven and just make a single serving.

  35. Jessica says:

    This was such a quick and easy sweet treat!

  36. Laura says:

    I didn’t have any oats so I used more flour instead and it turned out so good. I’m going to recommend this to my friends.

    1. Kristin says:

      Thank you Laura!
