This quick and easy Microwave Apple Crisp Recipe is made with 5 ingredients, in 5 minutes, all in one mug. The simplest fall dessert made for one!

I love serving mine with fresh whipped cream, vanilla ice cream, or vanilla Greek yogurt if you want to add a little protein boost. Apple crisp just isn't complete without something cool and creamy on top!

Quick Summary: This 5-Ingredient Microwave Apple Crisp is a healthy, single-serving fall dessert made in a mug by combining sliced apples with cinnamon and brown sugar, topped with granola, and microwaving for 2 to 3 minutes. It has all the warm, cozy flavors of traditional apple crisp without needing an oven, and with minimal cleanup.

As if apple crisp couldn't get any better, it's made in 5 minutes. In a mug. IN THE MICROWAVE. Like, hmmm I feel like apple crisp. BOOM. A couple chops here, mixy mix there, microwave, top with ice cream, inhale, repeat. I haven't thought this through or anything.

Why you'll love this microwave apple crisp

  • Single serving. Perfect for when you want a fall-inspired sweet, but don't want to peel a million and one apples.
  • Made in one mug. Keeping the dirty dishes and cleanup to a minimum, and no oven required by making it in the microwave.
  • Only 5 ingredients. You're just a handful of ingredients and the length of a commercial break away from the perfect little treat.

Ingredients

  • large apple
  • all purpose flour
  • brown sugar
  • cinnamon
  • granola
  • vanilla ice cream or whipped cream (for serving)

Instructions

Start by peeling, coring, and slicing a large apple. Firmer apples like gala or Granny Smith work much better than softer varieties like McIntosh, since they hold their shape better when cooked, and don't turn into a pile of mush.
Toss the apple slices in a microwave-safe mug with 1 teaspoon all-purpose flour, 1 teaspoon brown sugar, and ¼ teaspoon of cinnamon until coated.

Microwave Apple Crisp Recipe Ingredients

Top the apples with 1 ½ tablespoons of granola. If you have a cinnamon flavored granola, even better, but any type will really do. I prefer one without any added dried fruits or nuts for a more OG apple crisp flavor. Microwave it on high for 1-2 minutes, or until apples are softened. I like mine to have a slight bite left to them, but if you like your apples really cooked down, cook it for an additional 30 seconds to a minute longer. Carefully remove it from the microwave (it's gunna be HOT), top with ½ tablespoon more of granola, and a dollop of vanilla ice cream or whipped cream (optional, but is it really?)

Expert tips from a dietitian

  • Use a firm apple. I like Granny Smith, Honeycrisp, or Cortland best for best texture.
  • Add extra granola. Top with a sprinkle more granola after it's cooked gives that crunchy topping you know and love about apple crisp.
  • Up the protein. This healthy dessert already has 6 grams of fiber (whoop!) You can make this treat a little more satisfying by topping with vanilla Greek yogurt instead of ice cream or whipped cream for a little extra protein.

FAQs

What kind of apple do I use?

You can really use any apple you have, but my favorites are Granny Smith, Honeycrisp or Cortland, since they hold their shape better when cooked. As much as I love McIntosh apples, they turn to applesauce when cooked, so I try to avoid softer apples if possible.

Can I make this microwave apple crisp gluten-free?

You can certainly make this gluten-free by using your favorite gluten-free granola, and swapping the flour for a gluten-free flour, or cornstarch instead.

What kind of granola do I use?

My favorite types of granola to use are ones without any added fruits, nuts, or seeds, since those aren't typically used in an apple crisp. Vanilla or cinnamon flavored granola are my go-tos, but feel free to use your own favorite, knowing the flavor may change the overall taste of the crisp.
