Do you absolutely love the flavor and texture of apple crisp, but don’t want all the sugar and calories? Make your favorite fall dessert in a healthier way with this super yummy healthy apple crumble.

Made with lighter ingredients, this apple crumble is made without refined sugar. You can have your favorite fall dessert AND enjoy it in a healthier way.

What do I need to make a healthy apple crumble recipe?

  • Apples – the best apples for an apple crisp or cobbler are ones that are firm and with a slightly tart, sweet flavor. These include Granny Smith, Winesap, Jonagold, Honeycrisp or Braeburn.
  • Swerve Brown Sugar Substitute – this is a fantastic product for baking! Swerve eliminates the refined sugar without eliminating the sweetness or texture that traditional brown sugar offers.
  • Almond Flour – using almond flour instead of regular all-purpose flour eliminates the carbs, making it a healthier option.
  • Cinnamon – ideal for spicing the apples and crumble.
  • Nutmeg – a great addition to add to the apples for a bit of extra spice and flavor.
  • Rolled Oats – for this crumble recipe I recommend using old fashioned rolled oats, instead of quick-cooking/instant oats. Old fashioned will hold up better and not become mushy after baking.
  • Butter
  • Baking Soda
  • Salt

How do you make apple crumble?

  • First, start by peeling and slicing apples. To enhance the flavor of the apples, coat them in the Swerve brown sugar substitute, cinnamon and nutmeg. Place the coated apples in a baking dish.
  • Mix the cinnamon oat crumble. In a mixing bowl, combine the oats, almond flour, Swerve, baking soda, cinnamon and salt. Stir together with a fork to break apart the brown sugar. Pour the butter over the mixture, and combine. The mixture will be crumbly and have a gravel-like consistency.

  • Sprinkle the oat crumble over the top of the apples.
  • Before baking, loosely cover the baking dish with foil. This will ensure the oats will not overbrown before the apples are done cooking. About 10 minutes before the crumble is done baking, remove the foil to lightly brown the crumble before removing it from the oven.

Ingredient Substitutions and Recommendations:

  • Almond Flour – you can substitute regular, all-purpose flour at a 1:1 ratio.
  • Swerve Brown Sugar Substitute – for a more traditional (less light) crumble recipe, you can substitute regular brown sugar for the Swerve.
  • Butter – you can use coconut oil (I prefer unflavored Carrington Farms Coconut Oil) instead of butter at a 1:1 ratio.
  • Granular Sugar Substitute – you can substitute regular granulated sugar to sweeten the raspberries at a 1:1 ratio.

Frequently asked questions about making healthy apple crumble:

Why is my crumble not crunchy?

When making a crumble, it is important to create a lumpy, gravel-like consistency when adding to the top of the fruit. When baked, these lumps will create a crunchy consistency. Additionally, baking for an appropriate amount of time (25-30 minutes) will allow the crumble to become crisp.

Can I add nuts to an apple crumble?

Yes. Adding nuts, like sliced or slivered almonds, chopped pecans or walnuts are a great addition to a fruit crumble recipe.

What is the difference between a crisp and a crumble?

Fruit crisps and crumbles a pretty interchangeable, however, recipes that include oats in the topping are traditionally considered a crisp. A crumble will typically just include fat, sugar and flour for the topping.

How do I make apple crisp healthier?

An easy way to make a healthier crisp or crumble is to substitute the sugar with Swerve brown sugar substitute or a granular monk fruit sweetener. You can also substitute the butter for coconut oil and the flour with almond flour

What apples are best for apple crisp?

The best apples for an apple crisp or cobbler are ones that are firm and with a slightly tart, sweet flavor. These include Granny Smith, Winesap, Jonagold, Honeycrisp or Braeburn.

What can I serve with sugar free apple crisp?

Serving apple crisp with vanilla ice cream is a fantastic pairing. To keep it on the healthier side, I chose a sugar free vanilla ice cream. Other healthier options would be a low fat/low sugar vanilla gelato or sugar free vanilla yogurt.

This apple crumble would also be great paired with these fall-inspired drinks:

  • Chai Tea Latte
  • Whisky Apple Cider Cocktail
  • Hot Mulled Apple Cider

Equipment

  • Oval Baking Dish This Staub 9" Oval Baking Dish is perfect for baked desserts and casseroles.
  • Mixing Bowls These stainless steel mixing bowls are an essential cooking tool for every kitchen.

Ingredients
  

  • 5 cups apples peeled and thinly sliced
  • 1/3 cup Swerve brown sugar substitute
  • 1 1/2 tsp. cinnamon
  • 1/2 tsp. nutmeg

Crumble topping:

  • 1 cup Old fashioned rolled oats old fashioned oats are best
  • 1 cup almond flour
  • 1/2 cup Swerve brown sugar substitute
  • 6 Tbsp. butter melted
  • 1/2 tsp. baking soda
  • 1/2 tsp. cinnamon
  • 1/4 tsp. salt

Instructions
 

  • Preheat oven to 350 degrees. Lightly spray an 8×12" baking dish with non-stick baking spray. Set aside. (A medium oval baking dish, rectangular 8×12" baking dish or 9×9" pan will also work.)
  • To a mixing bowl, add the sliced apples, 1/3 cup of Swerve brown sugar substitute, cinnamon and nutmeg. Stir to coat the apples. Pour the coated apples into a prepared baking dish.
  • In a separate bowl, add the oats, almond flour, Swerve brown sugar, baking soda and salt. Stir together with a fork to combine. Pour in the melted butter and stir with a fork. Mixture should be crumbly and have a gravel-like consistency.
  • Sprinkle the oatmeal crumble mixture evenly over the top of the apples. Cover the baking dish loosely with foil. Bake at 350 degrees for 20 minutes, remove foil and bake another 10 minutes or until the oatmeal topping is golden brown.
  • Remove from oven and let cool for 10 minutes before serving. Great served warm with sugar free vanilla ice cream, a low-calorie vanilla gelato or yogurt.

Notes

Crumble is best served same day.
The crumble can be refrigerated for up to 3 days in an airtight container. I don't recommend leaving the crumble at room temperature, as the moisture from the apples will make the crumble topping overly soggy and unappealing.
To reheat, place a serving in the toaster oven or microwave until heated through.
