Microwave Apple Crisp with two spoons

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.

Note: Scroll down to the recipe card section of the post for the ingredients with amounts included and for more complete directions.

How to Make Microwave Apple Crisp

Making apple crisp in microwave is fast, easy, and delicious! Here are the basic steps:

  1. Stir together the crisp topping ingredients until the mixture resembles fine sand.
  2. Microwave the diced apple with butter to soften it, then stir in the sugar, spices, and cornstarch.
  3. Sprinkle the oat topping over the apple mixture and microwave again until the apples are juicy, bubbly, rich, and caramely.
  4. 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

By Averie Sunshine
🍎🍁 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!
Prep Time: 2 minutes
Cook Time: 3 minutes
Total Time: 5 minutes
Servings: 1

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.

Notes

Crumble is best warm and fresh, but leftover portion will keep airtight for up to 3-4 days. You can store the extra at room temp but the fridge is also fine. 
Optionally serve with ice cream, whipped topping, or caramel sauce
A Note About the Nutrition Stats – This is a generous portion of dessert for 1 person (I can’t finish it all and alway share half) so if you share it, or eat it between two sittings, the stats reduce, in half. It’s a treat, not something one eats daily, and therefore the stats reflect that.

    1. You can always reduce, to taste. There’s only 1/2 tsp here but you can reduce to 1/4, 1/8 or just omit next time.

  1. 5 stars
