Today I’m sharing my take on an apple crumble layer cake – this is the perfect cake to make and enjoy during the long autumnal days/nights.
This cake came to be after experimenting with flavours and preventing waste, plus why not combine a classic apple crumble with cake to make this perfectly seasonal apple crumble cake. Try not to get this cake confused with a crumble topped apple cake, which is equally as delicious.
I’ll be honest with you, this cake was an accidental creation. I had been making a apple crumble no-bake cheesecake and apple crumble cupcakes and had left over ingredients. So, to prevent food waste, I made this delicious cake. If you like sponge cake and apple crumble – you’ll love this cake.
The cake is made up of 2 layers of apple cake (made with fresh and dried apple), filled and coated with a cinnamon buttercream and finished with a crumble topping as decoration – it’s my take on a combination of an apple crumble and cake.
Anyway, let’s get started, shall we?
200g Brown sugar (you can use either light or dark, whichever you prefer or have available).
1 tsp Vanilla extract.
200g Plain flour.
1 tsp Baking powder.
Pinch of salt.
75g Cooking apple (peeled, cored and chopped).
10g Dried apple.
500g Icing sugar.
1 tsp Vanilla extract.
Ground cinnamon (flavour to your preference).
35g Granulated sugar.
35g Dark brown sugar.
50g Plain flour.
100g Granulated sugar.
1 tsp Vanilla extract.
1 Large cooking apple, chopped into small cubes.
30-50g Granulated sugar (use the amount of sugar that suits you best).
Before you get started on any element of this recipe, you’ll want to do some prep work. I recommend starting by weighing up all of your ingredients, getting any equipment you may need ready, such as a stand mixer, mixing bowls and spatulas. You will also want to preheat your oven to 180˚f/350˚f and line your 6 inch cake tins with butter and parchment paper.
To start on the recipe, you’ll want to start on the cake. Grab your mixing bowl and place in the butter and light brown sugar and beat the two together until they are lighter and fluffier in colour and consistency – this takes around 7-10 minutes on a medium-high speed.
You now start adding your eggs, one at a time, beating well in-between each addition. If you add your eggs too quickly, you may split the mixture and this sin’t ideal. You will also want to add in the vanilla extract, mix until it has been fully incorporated into the mix.
Don’t forget to give your bowl a good scraping down, this is just to incorporate any bits that may not have been fully worked in from earlier on.
Then you can add in the dry ingredients, passing them through a sieve first. This will help remove any lumps that may be in the dry mixture, meaning you won’t have any lumps of raw flour in your finished cake.
Mix all of the dry ingredients in on a low speed to start with, working your way up to a medium-high speed until the flour has been fully incorporated. Once the flour has been almost fully incorporated, you can add in the apple and mix on a medium speed until they are fairly distributed through out the cake batter.
Give the bowl another good scraping down, just to incorporate any little bits that may not have been fully worked in from earlier on.
Divide the cake batter between your two cake tins and level it out as best you can using a small cranked or offset palette knife. You can then place them into the preheated oven and bake off for 30-35 minutes (or until a tester comes out clean).
While your cakes are in the oven baking, you can make the buttercream and apple filling.
For the buttercream, grab your clean mixing bowl and place in the butter and beat for 5-7 minutes or until it has become lighter and fluffier in colour and consistency.
You can then go ahead and add in the first half of your icing sugar and beat on a low speed to start with, working your way up to a medium-high until the icing sugar has been fully incorporated. Repeat this stage with the remixing icing sugar.
Now you will want to add in the vanilla extract and mix until it has been fully incorporated. Give the bowl a good scraping down, just to incorporate any bits that may not have been fully worked in from earlier on.
Add in some ground cinnamon and mix until you have the desired flavour. The amount of cinnamon is up to you, I like quite a lot as I want to be able to taste the cinnamon.
To make the apple filling, take a large cooking apple and peel, core and cube. Then place into a medium-large saucepan and add in the sugar and water, heat over a medium-high heat and just cook until the apples have soften and the sugar/water have made a thickened syrupy consistency.
Transfer the apple filling into a jar until it’s needed, later on.
Now may also be the ideal time to make the simple syrup, which is probably the easiest thing to make in this recipe. Place the water, sugar and vanilla extract into a saucepan and mix together until they are combined. Place on the hob over a medium-high heat and allow to come to a boil, then simmer until the mixture has reduced and thickened slightly. Allow to cool fully before you intend on using it.
To start on the crumble, you’ll want to place the plain flour, granulated sugar and dark brown sugar into a bowl and mix them together.
Once they are combined, you can then add the butter, which is in small pieces. Once all the butter has been added, you can rub it together until the butter has been incorporated and the mixture has become crumblier looking – now you can add in the oats, stir until they have been incorporated.
Remove the crumble from the bowl and place onto a lined baking tray. If your crumble has lumps that are large, use a silicon spatula to break them down into smaller bits. Bake the crumble in the oven until it’s well coloured – around 10-12 minutes.
Now you have every element of the cake made, you can assemble it. To start, level your cakes – I remove the un-level top of the cakes and generously brush the layers of cake with the vanilla simple syrup I made earlier on.
Then grab the plate/board/stand you intend on using to serve the cake on and onto the centre of it, place a small blob of buttercream and smear it out and place the first layer of cake onto it, pressing down to secure it in place. This step acts as the glue, ensuring the cake is secure and won’t move around while you’re working with it.
Place a decent amount of buttercream onto the first layer or cake and spread out, leaving a slight lip on the outer edge, then add in the apple filling and place the second layer of cake on top, pressing down to secure it in place a bit better.
You can then go ahead and add a generous layer of buttercream to the entire cake, encasing the cake in the cinnamon buttercream. Usually, I’d suggest doing a crumb coat but this cake didn’t really need one as I wasn’t looking for a perfect finish. If you are looking for a more perfect finish, you can go ahead and do a crumb coat before applying the final layer of buttercream. If you do a crumb coat, chill in the fridge for around 45-60 minutes before applying the final layer.
Make sure you keep the sides smooth and have a little more buttercream on top of the cake, so you can use a small cranked/offset palette knife to make a swirl on top of the cake. This is probably the simplest and easiest way to decorate a cake – well I think so anyway. Feel free to decorate however you like!
To finish the cake off, I use the crumble mix around the outer edge of the cake just to add some decoration, colour and texture. You can incorporate the crumble a different way, if the way I mentioned doesn’t suit you.
That’s it. You can eat the cake straight away or chill in the fridge for a short while before you enjoy it.
That’s all for today guys, I hope you enjoyed. If you did, don’t forget to share this recipe with your family and friends and enjoy it.
