Single Serve Apple Crumble

Single serve apple crumble….for the times when you need an apple crumble in your mouth right away but don’t want to make a full recipe.

I LOVE apple crumble. I don’t make it very often, I also don’t eat it very often. But I do love it. It’s simple, I like that. 

So here’s a small version of one that you can make just for yourself!

Single serve apple crumble

Usually when making single serve recipes, I need to change certain ingredients for the recipe to work.

For example, with my single serve cookie, I had to find something to replace the egg.

However, for this recipe it’s essentially the same as a regular apple crumble recipe, the quantities for the ingredients are just smaller.

To make this, all we’re doing is cooking the apple filling in a pot, then making the crumble, putting these together and then baking it. That’s all!

Ingredients for the apple filling

Here’s the ingredients you’re going to need to make the apple part of this single serve apple crumble!

  • Apples – we can’t make an apple crumble without apples. I used 2 small apples, 1 large apple works too. Also any type of apples work, I used red ones….I don’t know what the exact apple is but they were in fact red.
  • Cinnamon – I kept this simple and just added some cinnamon into the filling but you can add any spices you want.
  • Brown sugar – the amount of sugar is adjustable. It honestly depends on the sweetness of your apples. For me 2 tablespoons was enough but you could add more.
  • Corn flour/Corn starch – this is to thicken the filling. 

Baking the apple crumble

I baked mine in a ramekin. Ramekins are great. I love baking things in ramekin.

But you don’t have to use one.

You can bake this apple crumble in any small dish that is oven safe. It doesn’t have to be a ramekin.

When it comes to actually baking this, the apple filling has already been cooked. So the only thing that really needs to be cooked in the oven is the crumble on top.

So we don’t need to bake this for long, around 10-15 minutes is enough. You just want the crumble on top to be golden brown!

Common questions

Do I have to use brown sugar?

I used light brown sugar in both the filling and the crumble.

No, you don’t have to use brown sugar. Any sugar will work. I like to use brown sugar though, just because it gives a good flavour.

Can I skip the oats in the crumble?

I like the way oats taste in any type of crumble, but it is not needed. You can leave them out. 

If you are going to leave them out though, you might not need to use the full 25g of butter.

I recommend only adding it in bit by bit. Once you get a crumbly mixture, you don’t need to add more!
