Apple Crumble Slices | Vegan, GF, Refined Sugar Free

apple crumble slices

Hi guys, as I’m sure many of you will know, I’ve been cutting out sugar recently. And while I’m eating it again now, cutting it out has made me wonder how many things can be made with no sugar or reduced sugar and still taste just as good. Today’s recipe isn’t added sugar free completely, but it is free from refined sugar. I wanted to keep things nice and seasonal and I thought what would be better than some cinnamon baked apples? The answer was something else baked that included the apples. I settled on these apple crumble slices.

This recipe, as the name would suggest, very crumbly. And although they’re slices, they’re not that portable. It gets messy. This is definitely more of a dessert rather than a baked snack or bar. Best served with some ice cream, cream or maybe even some custard for a proper autumnal dessert.  

The slices are prepared in three stages, the base, baked apples, and the crumble topping. Our biscuity base layer holds the apples and keeps it ‘slice’ intact. It’s firm and crunchy, then we have the soft baked apples and the crumble provides another crisp layer to finish it off.

Reduced Sugar

To keep the recipe lower in sugar, I opted for the same date syrup I used in my recent granola recipe. Simply mixing dates and water and heating it up to combine. You could always opt for an alternative syrup like maple or agave if you don’t want to make your own. Or buy date syrup if you live somewhere where a store sells stuff like that. I most certainly do not, so I stuck with making my own. 


The recipe says to leave it to cool before slicing. I know all recipes say something like that. I’m also aware it’s really tempting to cut and try something the second it leaves the oven. In this case, it’s important that you leave it. Cut it too early and the entire thing will fall apart due to its crumbly nature. Sorry. 

This recipe is dairy free, gluten free, soy free, vegan and contains no refined sugars.  

Prep time: 15 minutes 

Cook time: 1 hour 15 minutes 

Serves: 9 slices  



  • 1 cup GF oats 
  • ½ cup walnuts 
  • ½ cup almonds 
  • 4 tbsp sunflower oil 

Apple Filling: 

  • 4 cups apples, peeled and cubed (approximately 4 medium/ 3 large apples) 
  • 2 tbsp homemade ‘date syrup’* or alternative syrup of choice 
  • 1 tsp ground cinnamon 
  • Juice of a lemon 
  • 1 tbsp sunflower oil  


  • 2 tbsp syrup (whichever one you chose before) 
  • 3 tbsp GF oat flour 
  • A quarter cup GF rolled oats 
  • 1 tbsp sunflower oil  


  1. Preheat oven to 175°c and line a baking dish with greaseproof paper. 
  2. Add apples to a separate baking dish along with syrup, cinnamon, lemon, and oil. Toss to combine. 
  3. Cover with foil and bake for 18 minutes. Then remove foil and bake for 4-5 minutes more or until apples appear slightly caramelized and are tender to the touch. 
  4. While the apples finish baking, add oats and nuts to a food processor or blender until a fine flour forms. Add oil and syrup and pulse a few more times until a dough texture forms. 
  5. Spread the mixture into the lined baking dish and press down into an even layer with your fingers or a flat object. 
  6. Bake for 15 minutes at 175°c, then increase heat to 190°c and bake for 5-8 minutes more, or until the crust is fragrant and the edges are light golden brown. Be careful to check only the edges are golden. If it’s in the oven long enough to be golden all the way through, the base will be too dry. Set aside. 
  7. While crust is baking, prepare crumble by adding all ingredients to a small mixing bowl and using a fork or your fingers to mix ingredients into a crumble. Set aside. 
  8. Add baked apples and their juices/sauce to the pre-baked crust and spread into an even layer. Then top with crumble topping and spread evenly to cover apples. 
  9. Reduce oven heat back to 175°c and bake for another 15-25 minutes or until the apples are warm and bubbly and the crumble is golden brown. 
  10. Remove squares from oven and let cool – about 45 minutes.  Once cooled, gently lift bars from the dish. Slice into 9 even slices. 

Recipe Notes

*Date syrup recipe is as follows –

  • 75g pitted dates  
  • 150ml water 
  1. Blend the dates and water together then transfer the liquid to a small saucepan. On a low heat, warm the date mixture through for a few minutes until lukewarm. Stir regularly and do not allow to boil.

  2. This recipe has come at the most perfect time, I don’t know what it is but when it gets colder I love eating apple crumble and pie! This looks and sounds amazing. Hopefully it isn’t too complicated for me! Xx

  3. Oh yes! This is just what I want to try! Had a craving for something sweet earlier and this healthy Apple Crumble has totally tickled my taste buds! It sounds marvelous and the date syrup would add a gorgeous Toffee-like flavour which is really perfect to pair alongside the apple, especially at this time of year! Makes me think of Toffee apples!!

  4. That looks soooo good! I’ve had apple crumbles before that are way too sweet for me, I’m going to have to try this and see if it’s as good as it looks!

  6. Ah! Apple crumble used to be one of my absolute favorite fall recipies, espechially served with some vanilla ice cream! Although I have gone completely sugar free the last year I might have to make this for the family gathering at Thanksgiving because it looks fantastic and I know they will love it! Thanks for sharing it with us!

  7. Will need to try this recipe this weekend. One of my all time favourite childhood memory was baking Apple crumble with my Grandma and this just makes me miss her. She’s decided to retire in Asia whilst i’m 8 hours away here in the UK. Thank you for sharing this.

  8. These look delicious, and even better for me that they’re dairy and gluten free! Thanks for sharing, I’m definitely going to try and make these soon! B x

  9. I really love that this is cut down on sugar! I need to cut out sugar all I can in my diet, almost feels like everywhere I look, sugar is all around me in foods. This seems like a delicious recipe to try!

  10. We have an apple tree in our back garden and everytime they fall we try and make something different with them so this will be great to try! Thank you:)

  11. Man I wish we were friends in real life so I could come and sample all your gorgeous foods as there’s no way I could do recipes like this justice! I’ve never actually tried baked apple or any sort of apple crumble dessert but recently it’s really been appealing to me. As you mentioned cinnamon I would probably add a pinch in as I LOVE a bit of spice!

  12. I have been trying to eat cleaner lately and I really struggle when it comes to dessert. Trying to find options that include less sugar but still feel like a treat. I will definitely keep this recipe handy for those cold days you need a nice warm treat.

  13. I love that cutting out sugar got you to think outside the box when it comes to making food. The apple crumbles slices sounds delicious. I like how you used the date syrup – so much better than straight up sugar. It’s great that the prep time is so short. Thanks for sharing!

  14. These look absolutely gorgeous and I agree they’d be perfect with some custard for a proper autumnal pudding! I’d love to try these myself so thanks for sharing your recipe!

  15. I am not a massive fan of cooked apple but I think I would love this because of the cinnamon! My favourite autumn desert is a tricky one! But I do love cinnamon so anything with that flavour. I also really love gingerbread! Reading this recipe brought back lovely memories of when I used to bake with my Nannah. We would make apple and blackberry crumble around blackberry season. Going to try and make time to bake with her again soon! Thanks for the fab recipe xx
