Homemade Apple Crumble Slice filled with sweet apple slices and topped with an oat streusel crumble. Serve it cold or warm it up for a decadent dessert!
One of my favourite winter desserts is my classic apple crumble recipe. It's quick, it's easy and it's always a winner (especially on those freezing cold nights!). And so, I thought I'd switch things up and change it into an Apple Crumble Slice - a yummy treat that you can eat anytime of the day (breakfast included... of course!).
A classic apple crumble recipe with a twist
My apple crumble slice recipe has the same sweet and tangy apple and cinnamon filling as in my classic apple crumble dessert, apple crumble cake and apple crumble muffins... BUT it's baked between TWO layers of crumble (one on the base and one on top - talk about double trouble!).
The perfect crumble recipe
The crumble really is the star of this recipe - it's the perfect mix of crunchy, sweet and delicious. Plus, the exact same crumble mixture is used for the base and the topping, so you save yourself lots of time and effort!
This crumble recipe is the exact same recipe I use for my Creamy Lemon Crumble Bars and my Lemon & Blueberry Crumble Bars... it really is soooo good!
To make the crumble, you'll need:
- plain flour
- rolled oats
- salt
- bi-carbonate soda
- raw sugar
- brown sugar
- melted butter
- vanilla extract
*Please scroll to the recipe card at the bottom of the post for ingredient quantities and method
Step 1 - Mix the dry ingredients together
Step 2 - Stir through the melted butter and vanilla extract until everything is coated in the butter and the mixture resembles small balls or chunks.
Using the crumble mixture for the base and the topping
One of the best things about this recipe is that you simply divide the crumble mixture in half and use it for both the base and the topping. There's just a couple of little tips you need to know:
- use just over half of the mixture for the base. Press it down really (REALLY!) firmly in the baking tin.
- sprinkle the remaining crumble over the top - making sure you've got some nice little chunky 'balls' of crumble.
- lightly press the crumble topping onto the apple filling.
How to make the apple and cinnamon filling
The filling for this apple crumble slice is perfectly tangy and sweet!
To make the filling, you'll need:
- apples, peeled and thinly sliced
- plain flour
- raw sugar
- cinnamon
- nutmeg
*Please scroll to the recipe card at the bottom of the post for ingredient quantities and method
Then it's simply a matter of coating the apples with the flour, sugar and spices. These give the apples such a beautiful sweet flavour.
What type of apples are best for apple crumble?
You can use pretty much any type of apple you like for this recipe!
- Granny Smith apples give a tart flavour which contrasts nicely with the sweet cinnamon and the crunchy oat topping
- Pink Lady or Jazz apples are slightly sweeter (I generally use Pink Lady apples)
- Sweet red apples are also delicious
… the choice is yours!

Delicious. Chopped walnuts on top is nice too.
Beverley Nash says
Excellent recipe, really easy to make with the double crumble layer.
I used an old jar of ready made apple sauce and added custard powder to thicken it during cooking.
I substituted protein powder for flour, added ginger and sea salt to the crumble, and added 2 dessert spoons of runny honey to the mix. It worked brilliantly.
My main gripe is the quantity simply isn't substantial enough. It made 9 shallow and not very big pieces. Next time I'll make a double quantity and have it twice as thick.
