Apple and Custard Crumble Bars consist of chewy and crisp crumble base with a cooked apple and cinnamon middle, covered in a quick vanilla custard and topped off with more crumble. These are the perfect comforting treat!
This is the ultimate comfort treat! The soothing smells of baking cinnamon and apple, the crunchy crumble and the custard to go along with the apple crumble. The difference is taking a comforting dessert or pudding and turning that into a slice or bars. Apple and Custard Crumble Bars are guaranteed to become your new favourite dessert.
Serve these hot with a scoop of ice cream for an even better dessert!
Now I used a mixture of my buttery caramel oat slice and my apple crumble slice recipes to create the crumble recipe for this slice. I wanted the fullness and the almost oatmeal cookie feel of the caramel oat slice recipe and the cinnamon, crunchy feel of the apple crumble slice recipe.
The Apple Filling
For the apple filling I chose to use Granny Smith apples as I love the strong, tart flavour of granny smiths. You could use another apple that is in season or a mixture of apples for a less tart filling.
I also chose to cook half of the apples and leave half. This allows for a soft, apple filling with a hint of cinnamon and vanilla while keeping a bite from the fresh apple slices. I like to cut my apple thinly and in small chunks.
I made a 'cheats' custard using custard powder. You could make a proper custard with egg yolks but I found the custard powder version delicious and packed with vanilla flavour and was less fussy to make. However you want to make the custard is up to you.

Apple and Custard Crumble Bars
- ½ Cup Custard Powder (90g)
- ⅓ Cup Sugar (75g)
- 3 and ½ Cups Milk
- 1 Tbsp. Vanilla Extract
- ¾ Cup and 2 Tbsp. Butter, Melted (190g)
- 2 Large Eggs
- 1 and ¼ Cups Brown Sugar (215g)
- 2 and ½ Cups Oats (225g)
- ½ Cup Desiccated Coconut (50g)
- 2 and ½ Cups All Purpose Flour (300g)
- 2 teaspoon Baking Powder
- 2 tsps Cinnamon
- 4 Large Granny Smith Apples, Skin on and Sliced thinly and in small pieces
- 1 teaspoon Cinnamon, Extra
- 2 Tbsp. Water
- ½ teaspoon Vanilla Extract
- Add the custard powder, sugar and ½ cup of the milk into a large saucepan over a low to medium heat and stir with a whisk.
- Allow the mixture to slowly heat. After five minutes add the remaining milk and slowly bring to the boil stirring constantly.
- This may take some time but its worth it in the end as the custard will be silky and smooth.
- Once the custard thickens, take off the heat and stir through the vanilla extract.
- Set aside to cool and thicken while you make the rest of the apple crumble.
- Core and chop the apples. Add two of the apples, extra cinnamon, water and vanilla extract to a large saucepan.
- Heat over a medium heat until the apples are very soft, about 20-30 minutes.
- Remove from the heat and add the remaining chopped apples and stir through. Allow to cool as you make the crumble.
- Preheat oven to 180°C (350°F) and grease or line a 9"x13" baking tin with baking paper.
- Place the brown sugar in a bowl and mix in the melted butter.
- Add in the eggs and mix.
- Add the flour, oats, coconut, baking powder and cinnamon and mix until all combined.
- Press ⅔ of the mixture into the base of the prepared pan.
- Top with the apples and spread in an even layer.
- Pour over the custard and then sprinkle over the remaining crumble mixture and place in the oven bake for around 30 minutes. The top should be a light golden colour and the custard will be nearly set.
- Allow to cool completely before slicing. I like to cool mine in the fridge so the custard sets.
