Microwave Apple Crisp 🍎🍁 is ready in just 5 minutes and generously serves one person or can be shared by two. Top this FAST and EASY dessert with ice cream, whipped cream, or caramel sauce for the ultimate treat!

Easy 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.
- 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.
- This quick apple crisp serves one generously, or two more modestly if you feel like sharing.


Ingredients in Microwave Apple Crisp
- Apple: You can use almost any apple variety you like for this single-serving apple crisp. Fuji, Gala, Granny Smith, Honeycrisp, and Jonagold all work well. Fresh pears may also work, but I have only tested this recipe with apples.
- Unsalted butter, light brown sugar, old-fashioned oats, all-purpose flour, and salt: These make the buttery oatmeal crisp topping. I have only tested the recipe with old-fashioned rolled oats; quick oats are less chewy and may make the topping too dry.
- Granulated sugar, cornstarch, and spices: These coat the apple base so it cooks up sweet, warmly spiced, and slightly thickened rather than watery. Do not omit the cornstarch because the recipe will not turn out right without it. I use plenty of cinnamon and nutmeg, but you can reduce the spices to taste or add pinches of pumpkin pie spice, ginger, cloves, or allspice.
- Sugar: This is meant to be a sweet treat, and sugar adds both flavor and structure. You may be able to reduce the brown sugar slightly, but I would not reduce it much more than that.

How to Make Microwave Apple Crisp
Making apple crisp in microwave is fast, easy, and delicious! Here are the basic steps:
- Stir together the crisp topping ingredients until the mixture resembles fine sand.
- Microwave the diced apple with butter to soften it, then stir in the sugar, spices, and cornstarch.
- Sprinkle the oat topping over the apple mixture and microwave again until the apples are juicy, bubbly, rich, and caramely.
- Enjoy warm as-is, or top with ice cream, whipped cream, or caramel sauce for an extra cozy treat.



5-Minute Microwave Apple Crisp for One
Ingredients
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
- ½ teaspoon ground nutmeg
- pinch salt, optional and to taste
Apple Base Layer
- 1 medium 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)
- ½ tablespoon unsalted butter, or vegan butter substitute
- 2 tablespoons light brown sugar, packed
- 1 tablespoon granulated sugar
- 1 teaspoon cornstarch
- 1 teaspoon cinnamon
- ½ teaspoon ground nutmeg
- optionally add pinches ground ginger, pumpkin pie spice, cloves, allspice based on taste preference
Instructions
- Make the Crumble Topping
- 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
- 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.
- Cook for 1 minute on high power to soften apples.
- Remove bowl from micro and add the sugars, cornstarch, cinnamon, nutmeg, optional salt, optional other spices, and stir to combine and coat evenly.
- Evenly sprinkle with the crumble topping.
- 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.
- Serve immediately. Optionally serve with whipped cream or ice cream.

Single-serve, vegan, gluten-free and 5 minutes?! I think everyone is scrambling trying to make one right now!
Thanks Jasline, I hope so :)
Pure genius…yet so dangerous, Averie! I make a “skinny” baked apple (done in 3 minutes in micro) with stevia, lemon juice and spices when I’m watching what I eat but want a snack to satisfy the sweet tooth. LOVE the idea of adding the crumble when the mood strikes! A nice dollop of Greek yogurt or coconut milk ice cream would be divine. Perfect fall treat. Thanks for sharing!
And honestly, I don’t think this one is too bad. I don’t know if it’s ‘skinny’ per se, but it’s better than a Krispy Kreme or a DQ Blizzard :)
Wow, this recipe is so easy – I love it! Finally conquered the apple pie the other day and as happy as I was, it’s great to know there’s simple, easy recipes to make the next day :) This one’s autumn in a bowl!
Nice work on making an apple pie! And yes, simple is good, especially a few days after making a pie :)
You are killing me with all these single-serve recipes, Averie. I have a feeling that my pants are going to be a little tighter these days…
LOL!
This is so perfect, Averie!! Oh my gosh, I do not think this could get any better! That topping just looks like perfection and all those warm apple underneath? Just wow!! Wish this was breakfast!
And you posted apples today too. We are on a streak with apples/pumpkin on the same day!
I’m always skeptical when something is for one… but this recipe actually makes sense. I will give it try … thanks
I think it makes total sense! Sometimes you really only need/want one portion!
I can already see that this is going to be very very dangerous in my kitchen. Thanks for sharing!
I got really excited because I thought I had all the ingredients for this to make tonight. DANG if I don’t have oatmeal. Oh well, I need to go to the store anyway! :)
I always have a huge container of oats – both quickcooks and old-fashioned -just b/c they’re so versatile for baking. Oh well, you can go to the store later :)
Ok Averie, I’m officially very sad *this is not my breakfast right now! Amazing!!!
Oh Dear Heavens, can I eat this for breakfast? Looks amazing!!!!!!!!!!!!!11
Sure thing – Go for it! :)
I put the last apple in my lunch bag but promptly took it out and started chopping after reading this. It is quick and easy as promised (I was able to make it after only 1/2 cup of coffee)! I’ve already sampled it (excellent–love the thick sauce)!!! I doctored up some greek yogurt with stevia, vanilla, cinnamon and a bit of maple extract to have with it. I’m trying to save it until toward the end of the day–its going to be busy and I will need some sugar and spice to make everything nice! Half of it will probably be gone before I even get to work–but I think I read that this is appropriate breakfast fare too!
Ohmygosh! Leave it to you to make a recipe within a couple hours of going live and already with a field report! love.it.!! And yes to greek yog, stevia, vanilla, cinn, maple ext, wow – sounds great! That alone sounds like the makings of a frozen yogurt pop or a dip of some sorts! And yes, love the thick sauce this gets. Big fan of that myself :) Good luck with your day! Sounds like this will come in handy for you!
Looks so pretty I can smell it. I’m down with the apples and cinnamon for sure. I haven’t made any sort of crumble in a million years. I used to attempt a super simple one back when Jason and I first got together and I tried to appear domesticated!
LOL That is too funny! Well you appear pretty well :)
This is fantastic! One dish and ready in 5 minutes with a streusel topping?! Can’t wait to make thus when I need a quick one person sweet fix. Maybe some ice cream plopped on top?
And like I said in the post, if I would have had any (other than cookie dough – wouldnt really have worked for the pics) I would have plopped it right on! Or whipped cream/cool whip – any and all would be GREAT!
This is the perfect follow-up to your instant chocolate cake! Crumble on demand is going to require a pint of ice cream in the freezer as well…
Good thinking :)
Right now I have a bunch of strawberries about to go south. Do you think i would be able to use it here but add a bit more corn starch or use almond meal to thicken it up? Love this recipe nothing like a meal or dessert for one!
I personally wouldn’t put almond meal in it (that just sounds gross to me at the moment…LOL). I’d use a bit more cornstarch and/or a bit more flour if they’re particularly juicy berries. Yours may be juicier overall by using berries rather than with apples – which is a no-biggie to me :) ENJOY!
Yay recipes for one! Says the single girl:)
