What is Apple Crumble? 

Apple crumble is a sweet English dessert pudding that first became popular during World War II food rationing. It’s very similar to apple crisp or an apple cobbler.

The flavour of apple crumble is similar to apple pie but much easier to make. There’s no need to prepare or roll out shortcrust pastry, and no need to be worried about perfectly baking a double crust – instead, it has no lower crust, and only a simple crumble topping similar to streusel. 

It was super popular growing up in Australia as an easy and quick dessert with both our families, and we still love making it today. There’s nothing better than filling the house with the scent of homemade apple crumble in the oven, especially when the weather is cold outside.

What You’ll Need

For the apple filling:

  • Apples – Granny smith apples are a great choice for this recipe because of their crisp texture and sweet, tart flavour. Sub with pink lady apples or use whatever apples you have on hand if you need. Slice thinly or chop into chunks – it’s up to you!
  • Lemon Juice – This stops the surface of the apple slices oxidising and turning brown, helping them to retain their beautiful colour. Sub with apple cider vinegar for a little extra tart flavour, especially if you aren’t using tart apples.
  • Sugar – Regular white sugar / granulated sugar is fine. Choose brown sugar for a deeper caramelised flavour. 
  • Cornstarch – Aka cornflour, this helps to thicken the apple filling. Sub with regular flour if you prefer.
  • Cinnamon – We love the beautiful flavour and aroma that ground cinnamon adds to the apple crumble. Sub with pumpkin spice to amp it up even further. 

For the crumble topping:

  • Muesli – A nut or fruit infused muesli mix is a great way to add extra crunch and sweetness to your apple crumble. Sub with rolled oats or granola if you prefer. 
  • All Purpose Flour – Regular plain flour is all that’s required. You can also use self-raising flour if that’s all you have, or sub with gluten free flour if you need.
  • Butter – Salted or unsalted butter both work fine. We love salted butter, but add a pinch of salt if you use unsalted butter. Sub with Buttery Nuttelex to make it dairy free.
  • Sugar – As above, use regular sugar or raw / brown sugar for a richer caramelised flavour.
Ingredients laid out to make apple crumble.

How to Make Apple Crumble

First, gather your ingredients: See recipe card below for measurements.

  1. Preheat the oven to 180˚C / 360˚F, fan forced. Slice or chop your apples, removing the core. Optional: Remove the skins. (We like to keep them on).
  2. Place the chopped apples in a large mixing bowl and drizzle with the lemon juice, then give them a quick stir.
  3. Sprinkle with sugarcinnamon and cornflour / cornstarch, then stir again until the apple pieces are nicely coated. Transfer to a deep baking dish.
  4. Pour the apple into your baking dish, and spread out so the top is ready for the crumble.
  5. Pop the muesli (or rolled oats) in a medium mixing bowl with the sugar, flour and melted butter. Stir to combine. Tip: If needed, you can add a little extra flour until you end up with a slightly moist, mostly crumbly texture where the mixture holds its shape but isn’t too sticky.
  1. Spoon the crumble over the top of your apple pieces and spread until everything is covered evenly. Tip: Gently press down the surface with a spoon until it’s nice and even, OR rough it up with a fork for extra crunch once baked.
  2. Garnish your crumble with a little extra sugar (around 1 tsp).
  3. Bake for around 30-45 minutes or until the crumble topping is golden brown and the apples are soft. Serve hot with cream, custard or vanilla ice cream!

Wandercook’s Tips

  • Apple Skins – For the best texture and appearance, you should technically peel the skin off the apples. Otherwise, if you don’t care so much about that and prefer to save time, keep the extra nutrition in and avoid unnecessary waste – just leave the skins on!
  • Sugar – Taste the apples before adding sugar, then adjust the sugar you add in to suit. 
  • Crumble Texture – Press the crumble mixture down with a spoon until it’s nice and even, or keep it rough for extra crunch once baked! You can also sprinkle a little extra sugar over the top just before you pop it in the oven. The sugar caramelises on the top in sugary crunchy perfection.
  • Baking Time – You can adjust your baking time depending on the crumble texture you’re looking for. A shorter time will lead to a softer crumble topping, just like a soft baked cookie. Baking for longer will make it firmer and crunchier. 

FAQs

How do I know when my apple crumble is ready?

Carefully test the texture of the apples with a fork, skewer or knife – if it’s soft, you’re ready to go. If it’s too firm, continue baking for a few extra minutes, checking until the apples have softened.

Can I freeze it?

Yes, you can freeze apple crumble before or after baking. It’s a great way to be prepared for an upcoming party or save leftovers for later.

Can I make it in advance?

Yes, you can. The best way is to cook the apples, then allow to cool and store them (covered) in the fridge overnight until you’re ready to bake. Store the crumble separately and assemble just before baking.

Variations

  • Apple Garnish – Reserve a slice or two of apple to place on top of the crumble as a decorative heart.
  • Extra Crunchy Crumble – Add seeds or nuts like walnuts, almonds and hazelnuts in with the crumble mix. We also love sunflower seeds and pepitas!
  • Seasonal Fruit – You can use this same method with other fruits depending on what’s in season. Blackberries or raspberries, peaches or apricots, pears, persimmon, rhubarb, plum or even gooseberry are all amazing alternatives to a traditional apple crumble filling.
  • Spices – Swap out the teaspoon of ground cinnamon for mixed spice to add an extra later of depth to the flavour.

    Oh my, if crumble originates around wartime as a way to get creative, then pre-war Sunday lunches must have been very poor affairs. I practically grew up on crumble in the 70’s and 80’s – apple, rhubarb or gooseberry were the main contenders. I have happy memories of being put ‘in charge’ of making the topping as a kid and I still love a good crumble today. Now, I just need to lay my hand on that tasty muesli to make my next one extra special.

      Thanks for sharing your memories Jane 🙂 Hope you enjoy the muesli version just as much. We’re seriously so keen to give those gooseberries a try, they’re not easy to find here in Adelaide but we’ll just have to go on the hunt – they sound totally amazing!
