Crunchy Apple Crumble Made With A Whole Grain Oat Topping

A lovely crunchy “oaty” topping makes this apple crumble a superb dessert and the secret to a tasty apple crumble, or any fruit crumble, is not to over bake it.

If you do then the fruit turns to mush and you get a soggy chewy mess.

Not nice.

On the other hand if you don’t cook the fruit enough, you could end up breaking your teeth!

Not nice again.

Choose your fruits wisely and decide beforehand whether they can be simply put straight into the dish and baked or if they are hard unripened fruits, fry them off in a little butter to soften them slightly.

This recipe for apple crumble uses large cooking apples which are easy to bake and topped with a crunchy whole grain oat topping.


Reminds me of proper home baked puddings.

Full of crunch and soft summer fruits.

Other Fruit Fillings For Your Crumble Bake

Try to choose fruits that are in season and mix them up a bit. Many people like rhubarb mixed with something fruitier like strawberries but be careful not to over bake the soft fruits. Blackberry and apple crumble is a classic bake buit you can also mix it up with some raspberries, making it a true summer pudding crumble.

Oh the endless possibilities.

How To Serve Your Crumble Pudding

With soft simple vanilla ice cream melting gently over the top.

That’s my favourite.

If you’re looking for something sweeter, try a home made custard – or out of a tin – it’s easier!


Even easier is a little pouring cream and some extra fresh fruits carefully placed around the edge of your plate.

This crumble works beautifully when hot or cold so it can easily last a couple of days and still serve you well.


It is my favourite winter dessert along with a lemon baked cheesecake which is really light and tasty. Both are great for getting the family round and catching up with all the gossip whilst sharing a good old-fashioned hearty meal.

Recipe Notes

Pre heat your oven to fan 160 degrees centigrade and be careful not to overbake the fruits. If you prefer a deeper filling simply use a smaller dish but with the same amount of ingredients. Personally I love a deep crunchy topping, but I’m strange like that!
