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.

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.

How to Make Microwave Cinnamon Apple Crisp in a Mug
Step 1: Gather and prepare all ingredients.

Step 2: Make Topping
In a small bowl (affiliate link), combine the topping ingredients: 1-1/2 teaspoons canola oil, flour, 2-1/2 teaspoons Truvia Brown Sugar Blend (affiliate link), 1/4 teaspoon cinnamon and pinch of salt. Mix with a fork until thoroughly combined and crumbly.

Step 3: Prepare the filling.
In a mug (or microwave-safe bowl), combine the apple, 1 teaspoon Truvia Baking Blend (affiliate link), pinch of cinnamon and 1 teaspoon canola oil and mix well to coat the apple.

Step 4: Microwave apple mixture until tender.
Microwave the apple mixture for 5 minutes on HIGH, or until the apple is tender. Remove from microwave and stir.

Step 5: Add topping
Sprinkle the crumb topping mixture evenly over the warm apple mixture. Microwave on HIGH for 1-1/2 minutes, or just until the topping is set.

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
Enjoy this delicious dessert plain, or with your favorite topping. Some popular choices include:
- Lite whipped topping
- Plain (or vanilla) Greek yogurt
- Non-fat frozen yogurt or lite ice cream
