If you’re looking for the perfect Fall dessert, this is it! This comforting apple crumble with custard is made with cinnamon, ginger and is topped with a crunchy oat crumble topping. I then made homemade vanilla custard to pour over it. It only takes 30 minutes to prep this entire recipe!
This is one of the best desserts, it is so simple to throw together and will make your home smell just like Fall. Apple crumble with custard is a dessert I always have in England, definitely what I think of when someone says British baking!
Tell me about this recipe
- The apple crumble only takes a few minutes to throw together. All you need to do is toss sliced apples with some spices before sprinkling over an oat crumble topping.
- The topping is made with brown sugar, cinnamon and ginger. It gives you a delicious crunch to the crumble!
- I made a vanilla custard for this, but it also tastes delicious with ice cream or whipped cream.
The printable recipe card with the full list of ingredients and instructions can be found at the bottom of this post.
- Apples: I made this with cooking apples, also called Bramley apples, however I also tested this with Granny Smith and Braeburn apples and it tasted delicious!
- Oats: The topping is made with rolled oats
- Spices: I use a combination of cinnamon, ginger and nutmeg (which isn’t pictured above, whoops!)
How to make this recipe
One: Start off by mixing together all of your topping ingredients together in a jug or bowl. Place in the fridge
Two: Toss your sliced apples with the rest of the ingredients. Make sure the slices are evenly coated.
Three: Butter your tray, then pour in the apple slices. Make sure there is an even layer of the apples.
Four: Pour over the oat crumble topping. Bake for 50-55 minutes at 350 degrees.
Five: Beat your egg yolks, sugar and cornstarch together in a bowl. In a medium saucepan, heat up your vanilla, milk and heavy cream until it begins to simmer. Pour a cupful of the cream to the egg yolks, whisking constantly. Add another two cupfuls of the cream – by whisking constantly you make sure that you don’t scramble the eggs.
Six: Quickly clean out your pan, then pour the egg and cream mixture back into the pan. Stir constantly until it becomes thick enough to coat the back of a wooden spoon. The longer you cook this, the thicker it will get.
Seven: Pour your custard into a jug and place some plastic wrap against the surface – this stops it from forming a skin.
Eight: Allow your crumble to cool for at least 5 minutes before serving.
- Be sure that your thoroughly mix your topping ingredients, getting all the dry ingredients moistened by the butter. If you don’t mix them enough then your topping will be too dry after baking.
- Check on the apple crumble as it’s baking, if it starts to get too brown you can cover the top with foil.
- I highly recommend using a weighing scale and measuring out your ingredients the metric way. It makes a huge difference to your baking and is the most accurate way to bake
Frequently Asked Questions
Tricky question, it all depends on who you ask! Some say that crisps contain oats while crumbles do not. Richard Sax’s ‘Classic Home Desserts’ states that a crisp is topped with butter, sugar, flour and sometimes nuts, while a crumble is the English version of a crips with a topping of oats.
You can! Using cooking apples will give you a tart filling which contrasts with the topping, however if you use eating apples just add a bit more lemon juice.
Once your crumble has cooled down, keep it in the fridge for up to 5 days.

Do we need to whisk eggs with hands or can be done in a machine
I’ve only tried it by hand but you could try using a machine!
Picture of ingredients has ginger but the recipe card has nutmeg instead.
Hi there! Apologies, looks like the nutmeg didn’t make it into the ingredient shot! This recipe has both nutmeg and ginger (as well as cinnamon), but the ginger is only in the oat topping while the nutmeg is in the apple filling. Hope that helps!
