Our school was giving away some bramley apples, so it only meant one of two things! (other option was apple pie but I wanted something quickish).
The custard is completely homemade, as I didn't have any birds or instant in.. my first time making it and I didn't have any cornflour in so had to try and thicken it without haha
I didn't use measurements as I eyeballed it but for the crumble filling I peeled and sliced up an apple, sprinkled some sugar and cinnamon on it.
the topping I mixed plain flour with butter, sugar and a bit more cinnamon..
the custard I used 350ml milk, 3 egg yolks, sugar and vanilla extract.. you're best off looking up the technique for that as there are so many different recipes x
all in all not bad for a free pudding!
