All the cozy fall flavors with this Healthy Apple Crumble. With apples soaked overnight for extra flavor, this easy dessert is also high protein, low fat and contains no added sugar.

How good was this recipe?

OH MY GOODNESS! I gave my husband the plate as soon as I finished filming the recipe and he use quite some words here. To keep it simple – it was beyond delicious! Soft gooey apples with the topping – and all of this warm with some ice cream? Phenomenal!

Okay to be honest here, I only made this recipe because I wanted to make something apple because my Pumpkin recipes weren’t doing so well on Instagram. LOL.

The caramel apple combo sounded delicious, so I thought of a crisp recipe, but turned out I already had a healthy single serve caramel apple crisp recipe on my website. And also a strawberry apple crisp. Crumble was all that was left.

What are the best apples for apple crumble?

I had this exact question when I started planning my protein apple crumble recipe, and here’s what it is. The best apples for making apple crumble is a mix of Granny Smith & Honey Crisp in a 2:1 ratio for a perfect sweet-tart flavor.

So basically, for 450g apples, you want 300g Granny Smith + 150g Honey Crisp. If you had to pick between either one of them, I would say go for Granny Smith to get that tart flavor, and then add bit ofextra sweetener to the apple mix.

Ingredients for Healthy Apple Crumble Recipe

This easy and healthy apple crumble recipe is so because of the clean ingredients used. There’s no added sugar, only a little bit of butter and even protein powder for that extra boost.

The Sugar Free Apple Filling

Apples – I recommend a mix of Granny Smith & Honey Crisp (see above).
Vanilla Protein Powder to sweeten the filling without sugar; I recommend Dymatize or Isopure whey protein.
Zero Calorie Brown Sugar – This is the Brown Monkfruuit 1:1 Sugar Substitute from Lakanto, and keeps this recipe sugar free
Cornstarch
Some Lemon Juice
A bit of Cinnamon

For the High Protein Crumble Topping:

Flour: I used Whole Wheat Pastry Flour, but any plain flour works here
Vanilla Protein Powder – key for the high protein apple crumble with no sugar;
Again, Dymatize or Isopure whey protein.
Unflavored Protein Powder to replace some of the flour and give a lower carb, higher protein recipe.
I used the Multi-purpose Mix from Quest, but another good option is the Unflavored from KOS.

Cold Butter – This has to be cold!
Unsweetened Applesauce
Baking Powder

Instructions to make Low Calorie Apple Crumble with Protein Powder

Peel and core the apples.
Slice into thin pieces.
In a large mixing bowl, combine the apples and lemon juice. Toss lightly.
Add protein powder, granulated sweetener, cornstarch, and ground cinnamon. Toss everything together until the fruit is evenly coated.
Recommended: Set this mixture in the fridge for 4 hours or overnight for the flavor absorbs well.

Step 2: [After 4 hours or Next Day] Create the Crumble Topping

Begin by preheating your oven to 350°F (175°C).
In another bowl, mix together flour, protein powder and baking powder.

Combine with hands gently to form crumbles.

Step 3: Assemble the Protein Apple Crumble Topping

Transfer the prepared fruit filling into an 8” skillet or baking dish, spreading it out evenly.
There will be extra liquid; Only pour in a little bit of it.
Evenly distribute the crumble topping over the fruit mixture.

Step 4: Bake to Perfection

Place the skillet in the preheated oven and bake for approximately 20-25 minutes, or until the fruit is bubbling, and the topping is golden brown and only slightly crispy.

Step 5: Serve and Enjoy

Pour extra apple liquid over your weightwatcher friendly apple crumble.
Allow tje crumble to cool for a few minutes before serving.

I recommend topping with a scoop of ice cream and caramel sauce!
