Quick Microwave Apple Crisp

This microwave apple crisp is the best and easiest thing to make with all those apples you bought because they were on sale. You don’t need to turn on your oven and it’s ready in 5 minutes. And it’s single-serve, vegan, and gluten-free. So take that, traditional crisps.

I’m a big fan of crumbles, crisps, and anything with a crumbly or streusel topping. Those buttery, brown sugary nuggets with texture from oats get me every time. But while I like baking crumbles, usually I don’t need or want a whole pan. It’s the type of dessert that’s really best served warm, with a big dollop of whipped cream or ice cream on top, and after the first, warm juicy piece, the leftovers just don’t measure up.

No need to worry about leftovers here. This quick apple crisp serves one generously, or two more modestly if you feel like sharing.

When I posted the 5-minute Fudgy Chocolate Brownie Microwave Mugcake with Vanilla Glaze, I wondered what else I could make easily and successfully in the microwave. Cooking things in the microwave can be a finnicky proposition, but this came out beautifully and quickly.

Microwave Apple Crisp

The apple base layer, comprised of apples, tossed with (vegan) butter, cinnamon, sugar, nutmeg, and a pinch of cornstarch cooks in just a couple minutes after adding the topping mixture. The cinnamon, brown sugar, and oatmeal topping is tossed together in a minute.

The apples retain some slight texture, which is the way I like them. If they were pasta, they’d be al dente. I don’t like my fruit so soft that it turns mushy and these were just right.

I had cookie dough ice cream, but was out of vanilla, and didn’t have any whipping cream. I was getting ready to move and was trying to thin things down, but either would be wonderful on this warm, sweetly spiced, easy little number.

You get all the scent benefits that waft through the house as if you’d baked a traditional apple crisp, except you don’t have to heat up your house and it’s ready in 5 minutes.

Breakfast, snack, dessert, a midnight snack for one. So many ways to go with this microwave baked apples dessert.

How to Make Microwave Apple Crisp

First, make the apple crisp topping by stirring the ingredients together until they resemble the texture of fine sand. Then, lay the diced apple in a microwave-safe bowl and top with butter. Microwave 1 minute to soften the apples. 

Remove the bowl from the microwave and stir in the remaining apple crisp ingredients. Sprinkle the apple crisp topping over the apple mixture. Return to the microwave for another 2 minutes and cook until done. 

Done means juicy, bubbly, rich, and caramely. The brown sugar and butter caramelizes as it cooks, creating a thick sauce which coats the apples. It’s the best part. Well, that and the crumbly bits.

What Are the Best Apples for Apple Crisp? 

You can use really any apple variety you’d like for this microwave apple crisp recipe. I used a Fuji apple, but Gala, Granny Smith, Honeycrisp, and Jonagold would all work too. 

Can I Omit the Cornstarch? 

No, this quick apple dessert won’t turn out right if you skip the cornstarch.

Can I Make This Gluten-Free? 

Most likely, yes, although I’ve only ever made this recipe as written. You could try using a gluten-free baking blend in place of the all-purpose flour and see how it turns out. 

Can I Use Quick Oats Instead of Rolled? 

I’ve only made this recipe with old-fashioned rolled oats before, so I’m not sure if quick oats will work here. They’re not as chewy as rolled oats and might make the apple crisp topping too dry.

Can I Adjust the Amount of Sugar Used? 

If desired, you can add slightly more or less sugar than what the recipe calls for, depending on how sweet your apple is. I don’t recommend skipping the sugar altogether though, otherwise I’m not sure this would be a real apple crisp. 

Can I Use Other Fruits in This Microwave Dessert? 

I’m not sure! I’ve only ever made this microwave apple crisp with fresh apples. You may be able to substitute fresh pears, but I can’t say for certain.

Tips for Making Microwave Apple Crisp

I used a fair amount of both cinnamon (2 teaspoons) and nutmeg (1 teaspoon) because I’m fond them, and like things more boldly spiced. If you don’t like as much pop from cinnamon or are more sensitive to nutmeg, dial down the spices, to taste.

You could also work in pinches of pumpkin pie spice, ginger, cloves, allspice, or other warming spices you enjoy.

Make sure to use a microwave-safe bowl or baking dish that’s got enough room for expansion. The apples release a fair amount of juice, the butter melts, and the whole thing puffs and rises as it cooks. Take that into account so you don’t have an overflow situation.

With fruit-based recipes, because of the varying amounts of water released, cooking times may vary. And because microwaves vary as well, you may need to adjust your cooking time. Cook until yours is done.

Yield: 1 serving
Prep Time 2 minutes
Cook Time 3 minutes
Total Time 5 minutes


Crisp Topping

  • 2 tablespoons unsalted butter, softened (or vegan butter substitute)
  • 2 tablespoons light brown sugar, packed
  • 2 tablespoons old-fashioned whole rolled oats (use Certified Gluten Free Whole Rolled Oats if necessary)
  • 2 tablespoons all-purpose flour (or Certified All-Purpose Gluten-Free Baking Blend)
  • 1 teaspoon cinnamon
  • 1/2 teaspoon ground nutmeg
  • pinch salt, optional and to taste

Apple Base Layer

  • 1 medium/large apple, diced in about 1/4-inch cubes (I did not peel mine, peel if you wish; I used Fuji, use any variety you like)
  • 1/2 tablespoon unsalted butter (or vegan butter substitute)
  • 2 tablespoons light brown sugar, packed
  • 1 tablespoon granulated sugar
  • 1 teaspoon cornstarch
  • 1 teaspoon cinnamon
  • 1/2 teaspoon ground nutmeg
  • optionally add pinches ground ginger, pumpkin pie spice, cloves, allspice based on taste preference
  • whipped cream or ice cream, optional for serving


Make the Crumble Topping

    1. In a small bowl, combine all crumble topping ingredients and stir together with a fork until small pebbles and sandy crumbs form; set aside.

Make the Apple Base Layer

  1. In a small to medium-sized microwave-safe bowl or baking dish, add apples and top with butter. Don’t use an overly shallow dish because the apples will release juices, the butter melts, and it will rise and puff in the microwave, and it will overflow if bowl is too shallow.
  2. Cook for 1 minute on high power to soften apples.
  3. Remove bowl from micro and add the sugars, cornstarch, cinnamon, nutmeg, optional salt, optional other spices, and stir to combine and coat evenly.
  4. Evenly sprinkle with the crumble topping.
  5. Cook for about 2 minutes on high power, until juicy, bubbly, and topping is set. Due to variance in microwaves, climate, apples and their variable moisture content, cooking times could range from 1 1/2 minutes to slightly over 2 minutes. Start watching it carefully at 1 1/2 minutes and stop cooking when done; don’t overcook.
  6. Serve immediately. Optionally serve with whipped cream or ice cream.


Crumble is best warm and fresh, but leftover portion will keep airtight for up to 3 days.

  1. Oh Im so so sorry! *Averie

  2. what size bowl or baking dish did you use?

  3. I just made this–and I was proud enough to have all of the ingredients. I may have overcooked it a bit, but other than that, it tastes pretty good. Like, really pretty good. 

  4. Thanks for the feedback. Made the apple crisp–it was delicious! Thank you for the recipe. :)

  5. Well this was a pretty cool recipe – Easy Microwave Apple Crumble breakfast.  The spices were a little strong for me when I made it exactly according to the recipe.  For me, I had to cut the cinnamon and nutmeg in half the second time I made and then it was pretty good.

  6. I absolutely love this recipe, and have made it several times now. I was wondering if I could make it in the oven though, because I would like to make a few at the same time, without having to sit in front of the microwave for half an hour. At which temperature do you think should I try it out? And for how long should I cook them?

  7. This is a perfect dessert when you love apples and cinnamon. YUM!

  8. Great recipe thanks for sharing. Was about to try it but realized im out of corn starch ☹️. Any suggestion???

  9. Made this for my kids and it was soooooo fast and easy and super delicious. Two thumbs up from my kids and I!

  10. Is there anyway to adapt this to make it without sugar? I’m thinking of using this as a breakfast dish – but am also concurrently trying to cut out all sugar from my diet. Seems delicious – so I realize this might be a silly question, but thought I’d ask…

  11. I can’t believe how amazing this recipe is! Thank you for the great idea!

  12. This recipe turned out to be one of those that I will turn to frequently. I was looking for a recipe for a fruit crisp that I cold use in my mini microwave (only used for heating coffee& snacks before) as my regular oven broke down… I wanted to make a rhubarb crumble & wanted to know if it could be done in the microwave oven…I found most recipes called for quick cook oats which I don’t have so was very pleased when I found that your recipe used regular oatmeal…It was also easy to assemble & worked even in the low power micro oven…I cooked the fruit as directed & once the topping was on checked after the 2 minutes then gave it another 2 & it came out as well as I had hoped for.

  13. I was so glad I found this recipe, I LOVE apple crisp. Unfortunately I currently unable to use my oven so this was the best thing to come across. The only thing I disliked about it was that it was just too sweet for me. I will definitely be making it again, just with a little less sugar. Thanks you so much for this amazing recipe.

  16. I made this today but multiplied the ingredients by 3 and baked it in the oven at 375°F for 30 min. Turned out delicious! My two boys and I loved it. Thank you for the wonderful recipe.

  17. Just tried this with gluten free flour – turned out great, and perfectly satisfied the craving! Had to sneak around the house so my siblings couldn’t follow their noses and try to steal some! ;)

  18. I made this as a study snack and I LOVE THIS RECIPE! It is soooo easy and even more delicious. Thank you so much!

  19. I just made this , I think it’s really delicious. There is A LOT of sugar in this, I think I would halve the amount of sugar. I would also double the amount of crumble, mine ended up completely juicy/bubbly/gooey right up to the top. Also I made 2 of these for my partner and myself, but this could definitely feed a family of 4. Only one is needed for 2 people. But something I will definitely make again just with these small adjustments!

  20. This was simple to make but I found it impossibly sweet… my 7 year old loved it though. I think I would need to halve the sugar. Besides that great easy dish :)

  21. Yo… It’s over 1000 calories what the- Please tell me that’s a typo?! And 2 TABLEspoons of butter?? A tablespoon of butter is 100 calories just FYI… ummm… yikes…

  22. I love to add stevia in every recipe I cook because Stevia contains zero calories and can be up to 350 times sweeter than traditional sugar, so you can use much less in recipes.
