Ingredients in low calorie apple crumble for one
Exact ingredient quantities can be found at the bottom of this page.
To make this low calorie apple crumble for one you will need:
An apple – You need one medium apple for this recipe. I often use royal gala apples as they have a tender, sweet and mild flavor profile. You can use any apples you like though, just make sure they’re firm and not mushy or soft.
Ground cinnamon – A must for any fall sweet treat!
Lemon juice – To balance out the sweetness of the apple and add a little tartness.
0 calorie brown sugar – My go-to for any cozy, spiced fall dessert! You can use any 0 calorie granulated sweetener for this recipe but be mindful of the conversion. The sweetener I used is a 1:1 ratio of sweetener to sugar so adjust accordingly.
Light butter – I use flora lighter spread which has 25 calories per 10g making it a great low calorie binder for the crumble whilst adding a little moisture as well. You can swap for an equal amount of unsweetened applesauce or regular butter. If you choose to use regular butter, the calories will increase by around 50 calories.
Plain/all-purpose flour – This recipe calls for plain flour to make the crumble. You can use gluten-free flour for a gluten-free version. You can also swap the flour for more oats in a 1:1 ratio if that’s your preference.
Oats – To add a little crunch and different texture to the crumble.

How to make low calorie apple crumble
- Pre-heat oven to 190°C (370°F).
- Grab a small saucepan and add the diced apple, 0 calorie brown sugar, lemon juice and ground cinnamon. Give them a quick mix to coat the apple chunks and set over low heat to soften. Cook the apples, stirring occasionally until they’re soft and have released most of the water, about 5-7 minutes. Remove from the heat and set aside to cool.
- In a small bowl, mix together the butter, sweetener, flour, oats and cinnamon until well combined. It might be easier to use your hands to create a soft, crumbly mixture. Set aside.
- Transfer the slightly cooled apple chunks to a 9cm ramekin, cover with the crumble and place in the oven. Bake for 20 minutes or until the crumble turns a golden brown. Set aside to cool for a few minutes.
- Serve and enjoy! I love to top mine with a little greek yogurt or for an even more indulgent treat, with a little vanilla ice cream!
Top tips
Measure carefully – It is so important to measure according to the recipe not only to ensure the correct amount of calories, but to also get the best results. Use a kitchen scale to measure and for spoon measurements, use the back end of a knife to level it out.
Eat warm – This apple crumble is made to be eaten warm (duh) but don’t let it cool too much. I like to give it a few minutes to cool just so it doesn’t burn my mouth!
Top with ice cream – I loveee this crumble with some low calorie ice cream. Paired with a really good vanilla ice cream, this low calorie apple crumble feels like the most indulgent autumnal sweet treat!

Looks yummy. Does it warm up good? I was thinking of meal prepping these for daily snacks.
Hi Punkin, it does taste good warmed up after being in the fridge but the topping does go soggy which isn’t great for a crumble. If you don’t mind the texture though, the taste is still great! Hope that helps 🙂
What can i use instead of applesauce? I dont have it available here
Hi Mel, you can replace applesauce with the same amount in melted low fat butter!
Hi! I just made these crumbles and while it’s delicious, the crumble part did not turn out like your picture, it was basically flour like with oats mixed in. Am I missing something? I feel like it needed butter or another ingredient to make it crumbly into the small balls as it says.
Thank you! I am loving your recipes!
Hi Ruth, I’m so glad you enjoyed this recipe! Did you add applesauce to the flour and oats? The applesauce should bind it to make it crumbly!
