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.

What’s in This Microwave Apple Crisp?

To make this quick microwave dessert, you’ll need:

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

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
  • 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

Instructions

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.

Notes

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

  1. LOVE this!!!!!!! I adore crumbles and crisps too and have made apple crisps for two in the oven, since we never need a big pan of it either — never thought to just do a microwaveable version for ONE! This is seriously dangerous :) in the best way. Thanks so much for the genius recipe!

  2. Ooooh, I love this!! Perfect that it’s only one serving – more would just be dangerous. ;)

  3. Averie, your website is AMAZING!!! I love all your recipes – this one looks like fall in a bowl and DELICIOUS! Keep the great posts coming!! Carole

  4. You are so a genius Averie. I MUST make something like this! I really should be making more single serving things. Way better for the waistline!

  5. without a doubt, the BEST single serving dessert EVER!!

  6. I don’t know whether to want to love you or hate you right now.. but I’m leaning towards love because if you call that a single serving, you’re my kinda girl! That’s HUGE and the PERFECT xxl-solo size for someone who gobbles apple crisps like her life depends on it. Well… it does, kinda :)

    • I will say that the dish does look rather huge in the photos but in person, it really isn’t. Something about the white, the rim, the angles, yes I thought the same thing :) It’s still a generous single-serving, but not quite as generous as the photos make it seem like LOL :)

  7. You are so right, there’s nothing like a buttery, brown sugar crumble. Now if only this would magically appear for my breakfast!

  8. I second the voices saying this deserves a scoop of ice cream–dessert for brekkie, maybe?? I think this could totally stand in as a bowl of my usual “oatmeal”…although then the ice cream might be overkill. Thoughts/endorsements, Averie? :) YUM!

  9. This is genius, Averie! How perfect for satisfying my sweet tooth any night of the week!

  10. This is going to be deadly, with a scoop of vanilla ice cream?! Oh my, I love!! Brilliant :)

  11. If you keep coming up with these brilliant 5-minute microwave goodies, I’m going to gain so much weight!

  12. Yummy! I am a bit addicted to apple crumble to I’ll be trying this recipe out for sure! Gosh I could get so lost looking through all your amazing recipes! Thanks

  13. Gurrrrrrl, you had me at 5-minute!! And then I read the rest…holy *insert 4 letter word*… I want to be your neighbor!! Come back to Chicago. hahaha

  14. What a brilliant idea! Then you’re not stuck with a ton of leftovers that you feel porky for eating :-) Love it! Pinning now…

  15. I need to rethink the relationship I have with the microwave, this looks scrumptious!!

  16. I agree that some dishes come out of the microwave yucky, but this looks wonderful! So quick, easy, and decadent.

  17. This looks delightful!

  18. I missed this recipe when I was out of town and am just now seeing it. I am definitely going to try this tonight!!

  19. This was heavenly! I couldn’t even wait to put whipped cream on it, straight from the microwave to the fork!

  20. Oh, this sounds like heaven! I will definitely have to try it sometime soon :D

  21. I tried making this and it’s so delicious!! But I had trouble with the topping. Mine didn’t turn into small pebbles and sandy crumbs. It was all just kind of one butter blob. But it was still good!! Is there any way you could post a picture of what the crumble topping should look like before putting it on the apples? Thank you for this recipe!

  22. The only fruit I had was frozen bananas but I did have a can of cherry pie filling so I thought I’d give that a whirl. Nope! It definitely needs the fresh fruit juices to turn the top into a crumble. Next time I’m holding out for the real deal.

  23. so, YUM! I made this tonight (even though I had a mini panic attack upon finding my cupboard completely devoid of brown sugar!) and it was absolutely a little piece of heaven. Real butter, my goodness, soooo decadent. White sugar did fine in place of the brown, although not nearly as pretty after being cooked. Topped with some vanilla chip ice cream, this made my soul sing with delight. Thank you SO much!

  24. Has anyone calculated the calories in this dish? BTW best GF apple crumble I have ever had…you are bookmarked in my tool bar. I had all the ingredients including the GF rolled oats so it was easy to make! Loved it :)

  25. Avery this looks SO perfect I can’t wait to make it for brunch! Tell me, is it the same to use red or green apples? Love :)
