This healthier version of the traditional apple crumble is really easy to make and is truly mouth-watering. It also has the added bonus of being gluten-free, refined sugar-free, and has a lower carb count than many other recipes. By using a combination of almond flour, oats and a sugar alternative helps to make this crumble a little kinder on blood sugar levels.

Why I love this Apple Crumble with Oats (no flour)

First off, in this recipe, instead of the more traditional pairing of apple and cinnamon, this apple crumble with oats actually uses lemon instead. This gives the stewed fruit a lovely tangy flavour which I think pairs beautifully with the sweet buttery crumble topping. It makes for a refreshing change to the usual crumbles.

Secondly, this apple crumble is easy to make and can even be made in advance. It just takes a little extra preparation time pre-stewing the apples and pre-baking the crumble topping to get that extra short texture. If you are making this crumble in advance then follow the instructions below on the recipe card and simply stored the assembled crumble in the fridge until you are ready to reheat it.

Lastly, switching out the refined sugar for xylitol and the addition of almond flour and oats makes this dessert a great lower carb count option. Oats have a low glycemic index which can be a really good choice for diabetics and blood sugar management. But I appreciate what works for us may not be the same for you. However, we have found that by choosing a low GI option such as oats, means that your body will be slower in turning the carbohydrate to glucose resulting in a more delayed and potentially a smaller rise in blood sugar levels.

The Best Apples to choose for your Apple Crumble

Without a doubt, the best apples for an apple crumble are Bramley apples. These are often sold as cooking apples as well. These apples tend to have a sharper flavour to them but just seem to work best when cooked as they retain their flavour. I have tried experimenting with lots of other varieties and they just don’t seem to stew in the same way as a Bramley. Some have even come out as rubbery little pieces, which is not a pleasant eating experience I can tell you!

Note on sweeteners

In this recipe, I use a white sweetener which could be either xylitol or erythritol. Both are a 1:1 substitute for sugar and work brilliantly in cakes and desserts

My preference is xylitol and my current favourites are NKD Living Natural Xylitol and Total Sweet Xylitol

If you prefer to use different sweeteners like sucralose or stevia, remember to convert your quantity. Most brands have this information on their websites.

Don’t be afraid to experiment with different sweeteners and the quantities in sweet recipes. It may take a few attempts to find your preference as we all have a different palate.


What you will need to make this apple crumble with oats (no flour):

For the oaty crumble topping

  • Gluten-free oats
    • Oats are naturally gluten-free however it’s in the processing of them that contamination with other cereals may occur.
    • Therefore I use GF as my husband has an intolerance however any type of porridge oats can be used.
    • Oats are such a magnificent superfood; they are wholegrain, a great carbohydrate source, and full of fibre, essential vitamins, minerals and antioxidants.
  • Ground almonds
    • These are not only gluten-free but add an extra nutty flavour and are a great no carb-count option for baking
    • High in healthy monounsaturated fats, fibre and protein
  • Chopped almonds
    • High in healthy monounsaturated fats, fibre and protein.
    • Loaded with antioxidants
  • Sugar Replacement
    • I used Xylitol but you could also use any sweetener you prefer
    • However, see notes above on sweeteners if using another type
  • Butter
    • High in saturated fat
    • You could also use coconut oil if you prefer

For the stewed apple:

  • Apple
    • A great source of fibre and vitamin C
    • They also have a low glycemic index which means the carbs enter the bloodstream more slowly, so there is a lower risk of a blood sugar spike.
  • Sugar Replacement
    • I used Xylitol but you could also use any sweetener you prefer
    • However, see notes above on sweeteners if using another type
  • Lemon
    • Adds a wonderful zesty zing to the dish
    • Gives an extra dose of vitamin C

How to make apple crumble with oats (no flour):

For the stewed apple, peel and prepare your apples. Then place the apples into a pan on a medium heat with the sugar replacement, 3 tbsps of water, the lemon juice and zest. stir to combine. Pop the lid on the pan and leave them to simmer gently for around 20 minutes, stirring occasionally.

While the apple is stewing you can make the crumble topping. Firstly, preheat the oven to 180 C fan / 200 C. In a bowl mix the oats, ground almonds, sugar replacement and butter with your hands until you have a breadcrumb-like texture. Add the chopped almonds and mix in well. Then place the crumbs onto a baking sheet and bake in the oven for 15 mins turning them halfway through.

Once your fruit and crumble are prepared it’s time to assemble. In an ovenproof dish (25×25) add your layer of apples and then the crumble top.

If you’re making in advance leave to one side or once cooled cover and keep overnight in the fridge. Just increase the cooking time by 10-15 minutes. Otherwise cook the crumble in your preheated oven, 160 C fan / 180 C for 30 minutes.


How to Serve your Apple Crumble with oats (no flour)

OK, so I know this all comes down to personal preference but for me without a doubt, it has to be a big dollop of vanilla ice cream. Now the rest of my family would definitely disagree and opt for a custard. So what camp do you stand in?

Oh and by the way, this apple crumble with oats and no flour is also super delicious eaten cold as well!

Other options for this crumble dessert:

Apple crumble is always a go-to favourite pudding in the colder months, however, changing the fruits to make it more seasonal is actually a great way of enjoying your crumble all year round.

Suggestions for alternative fruit options:

  • Blackberry
  • Rhubarb
  • Blueberry
  • Strawberry
  • Mixed Berries

How to Store any Leftover Apple Crumble

If you are lucky to have any leftover crumble either cover the dish or transfer it into a lidded container and pop it in the fridge. It will happily keep for up to 4 days.

Either eat your leftover apple crumble cold, or reheat it in an oven set to 180C / 160C fan for around 10-15 minutes. Sometimes I pop a little foil on to stop the crumble from browning too much. Alternatively, you can reheat in the microwave which is a much quicker option!

This crumble is also suitable for freezing where it will keep for up to 6 months. Just defrost and reheat as above.

Oats = 150g – 106.1g of carbs

Raw Apples = 1200g – 106.8g of carbs

Now add all the carbs together – 106.1+106.8 = 212.9g

Finally divide this by the serving size, 6 – 212.9/6 = 35.5 g of carb per serving

Please note these are pretty generous serving sizes!

This carb count amount per portion is based on the standard ingredients listed above and may differ depending on what you use and how much you choose to eat.

    Everyone loves a crumble and this was absolutely delicious, especially with custard.
    I followed the recipe and made it the day before, but I didn’t put the topping on until I was ready to cook it the next day.

    I found that by putting the sugar alternative in the pan with the lemon and water and then adding the apples,was not such a good idea as the Sukrin I used burnt, so next time I will layer the apples in the pan and sprinkle the sukrin in between.
    Highly recommend if you love a crumble.

    • Thanks so much for your insightful comments and yes I find sprinkling the sugar replacement over the apples helps prevent burning. I’m so glad you enjoyed it!
