Aimee’s Recipe Notes

Taste & Texture: Soft cooked cinnamon spiced apples with a crispy oat topping.

Make ahead: This dish can be assembled in the morning and baked for dessert!

Ease: No need to peel the apples for this recipe. Dice and bake!

Serving Suggestion: This apple crisp is delicious served warm with a scoop of vanilla sugar-free ice cream.

Ingredients for Apple Crisp

To make my sugar free apple crisp, scroll down to the recipe card for the complete list of ingredients with measurements.

  • Apples- I love using a combination of sweet and tart apples. Granny smith with honeycrisp is what I used today!
  • Monk Fruit Sweeteners- I use these monk fruit sweeteners in my sugar free apple crisp. They are zero calorie, zero carb and completely natural. You’ll need the granulated and the brown sugar versions. Stevia can also be used.
  • Almond Flour- Adds a nutty flavor, delicious texture, and keeps the recipe gluten free. King Arthur Measure for Measure gluten free flour or an all-purpose flour can be substituted.
  • Oats- Choose old fashioned oats instead of steel cut. If wanting gluten free, be sure to check your packaging!

Don’t forget the sugar free ice cream on top! Use my mason jar ice cream recipe to finish this delicious dessert.

This fall-spiced Sugar Free Apple Crisp recipe is made with fresh apples, cozy spices, and has a delicious oat crisp topping. This simple recipe is naturally sugar free and gluten free!
Prep Time: 15 minutes
Cook Time: 45 minutes
Servings: 8 servings

Ingredients 

For the Filling

  • 4 apples, cored and diced
  • 1 Tablespoon fresh lemon juice
  • 2 Tablespoons granulated monk fruit sweetener
  • 2 Tablespoons brown monk fruit sweetener
  • 1 teaspoon cinnamon
  • 2 Tablespoons cornstarch

For the Crisp Topping

  • cup brown monk fruit sweetener
  • 1 cup almond flour
  • 1 cup old fashioned oats
  • ½ cup unsalted butter, cubed
  • 1 teaspoon cinnamon
  • ½ teaspoon kosher salt

Instructions 

  • In a large bowl, combine the diced apples with lemon juice, monk fruits, cinnamon, and cornstarch. Pour into a 2 quart baking dish (or 8-inch square).
  • In the same bowl, combine crisp topping ingredients. I use my hands to combine the butter until crumbly with the oats, etc. Sprinkle over the apples, press lightly.
  • Bake crisp in a 350 degree oven for 45-50 minutes until bubbly and golden in color. Remove from oven and cool 10 minutes in pan. Serve warm with sugar free vanilla ice cream.

Notes

  • To make this recipe easy, I don’t bother peeling the apples. They cook long enough to make the skins soft and unnoticeable. If you prefer to peel them you can.
  • Apples– I like to use a combination of granny smith or golden delicious with gala or honeycrisp. Tart with sweet!
  • Make ahead– apple crisp can be prepped 24 hours ahead of time and refrigerated until ready to bake.
  • Double it– use a large foil pan (lasagna pan) and double the recipe easily for a crowd.
  • Monk fruit– I prefer using Besti monk fruit on Amazon, but stevia works great too as another natural sweetener.
  • Almond Flour- I love keeping this recipe gluten free and the almond flour adds a delicious nutty flavor. You can swap this for all-purpose if you prefer.
  • Storage– keep leftovers in covered container in the refrigerator for up to 4 days. Reheat and serve with vanilla ice cream.
