I’ve always loved old-fashioned apple crisp, but I don’t always want to heat up the oven or be left with a big pan of dessert calling my name. That’s why I’m such a fan of this microwave (affiliate link) cinnamon apple crisp for one. It’s quick, easy, and the perfect way to satisfy a sweet craving without derailing your WW goals.

This healthy apple crisp comes together in minutes with just a few simple ingredients and cooks right in the microwave (affiliate link). The apples turn tender and fragrant, the topping gets warm and spiced, and in less than 5 minutes, you’ve got a cozy single-serve dessert that tastes just like fall. I like mine topped with a little whipped cream or Greek yogurt for breakfast, but it’s equally delicious on its own or even with a small scoop of vanilla ice cream.

Why I Love This Microwave Apple Crisp for One

  • Quick & Easy: Ready in minutes with no oven required.
  • Perfectly Portioned: A single-serving apple crisp so you can enjoy dessert without leftovers.
  • WW Friendly: Lightened up with low-calorie swaps to keep it points-friendly.
  • Versatile Treat: Enjoy as dessert, a healthy snack, or even a breakfast topped with yogurt.
  • Cozy Fall Flavor: Warm apples, cinnamon, and a sweet crisp topping — comfort food in a mug.

Ingredients & Substitutions

  • Apple – Any firm apple works here (Granny Smith for tartness, Honeycrisp or Fuji for sweetness, or my favorite Pink Lady).
  • Canola Oil – Helps crisp the topping; melted butter or coconut oil can be substituted.
  • Flour – Provides structure for the topping; whole wheat or oat flour (affiliate link) also work.
  • Truvia Brown Sugar Blend (affiliate link) – Adds sweetness and that classic brown sugar flavor with fewer calories; substitute light brown sugar if preferred.
  • Truvia Baking Blend (affiliate link) – Another lightened-up sweetener; regular sugar works too, just adjust WW Points.
  • Cinnamon – The classic spice for apple crisp, but nutmeg or apple pie spice can be added for extra warmth.
  • Salt – Just a pinch balances the sweetness and enhances the flavors.

Step 6: Let cool

Remove from microwave and let crisp stand at room temperature for at least 15 minutes, alternatively refrigerate for 5 to 10 minutes, before serving.

Step 7: Enjoy

Enjoy plain or with your favorite topping—lite whipped topping, Greek yogurt, non-fat frozen yogurt or lite ice cream would all be delicious.

Recipe Notes

  • I was able to reduce this recipe by 3 Points by substituting canola oil for butter (also making this dessert dairy-free), reducing the total amount used and reducing the amount of flour used in the topping.
  • The original recipe was a little too sweet for me with too much crumble topping. After making less topping and substituting Truvia for the white and brown sugars, I thought the sweetness level was much better and the apple mixture was better balanced with the topping and didn’t get overwhelmed.
  • Try making Cranberry Apple Crisp by mixing in some chopped dried cranberries with the apples before cooking.

Serving Suggestions

  • Lite whipped topping
  • Plain (or vanilla) Greek yogurt
  • Non-fat frozen yogurt or lite ice cream
