Ingredients

For the fruit mixture:

1 kg Cooking apples See notes
50 g Caster sugar
1 tsp Cinnamon

For the topping:

175 g Plain flour
100 g Unsalted butter Cut into cubes, straight from the fridge
100 g Caster sugar
25 g Oats

Metric - Imperial

Instructions

If using fresh peel and core your apples and cut each one into 3 even-sized pieces. (If they have seeds, scoop them out with a teaspoon.)
Put the apples into the bottom of the slow cooker and sprinkle with the sugar and cinnamon.
In a small bowl, put the flour and butter. With clean hands 'rub' the butter in. You do this by putting both hands into the bowl and lifting up some butter cubes with some of the flour and rubbing between your finger tips, letting the mixture fall through back down into the bowl. Repeat until the mixture looks like damp, lumpy sand!
Stir the sugar and oats into the crumble mixture and sprinkle over the apples.
Put the lid on the slow cooker, with a clean tea towel covering the top of the slow cooker, under the lid. Cook on HIGH for 3 hours.
After the cooking time, remove the damp tea towel and put the lid back on the slow cooker, but sit it on the cooker ajar so the moisture can escape. Cook for a further 30 minutes to allow the crumble mixture to firm up.

Notes

Cooking apples: This is the PEELED and CORED weight. I used 2 x 500g/1.1lb bags of Aldi Frozen Bramley Apples which worked brilliantly. The quantity would be about 6 - 8 Bramley cooking apples if you’re using fresh.

Oats: I used Jumbo for texture but regular rolled oats are fine too.

Non-stick: If your slow cooker is ceramic or NOT non-stick, you may want to wipe the inside edge of it with some sunflower oil before you add it to the pan so that the crumble doesn't stick.

To serve: Dish up on its own or with your favourite accompaniment (cream, custard or ice cream).
