To Make the Crumble
Preheat the oven to 180C (160C Fan) and line a baking tray with baking parchment. Leave to one side.
In a large bowl rub together the flour, butter and sugar until it resembles breadcrumbs.
Sprinkle the mixture onto the baking tray and bake in the oven for 15-20 minutes or until golden brown in colour.
Remove from the oven and leave to one side to cool.
To Make the Salted Caramel Sauce
Measure out the cream in a jug and leave to one side.
Measure out the butter and cut it into small cubes and leave to one side.
In a saucepan add the sugar and water and pop onto a low/medium heat.
Once the sugar has dissolved stop stirring and leave the mixture to come to the boil.
Once the mixture is boiling, leave it until it turns a lovely amber colour, and then remove it from the heat. This can take up to 10 minutes.
Whisk the caramel and add in the double cream. This will bubble and spit so please be careful. Keep whisking as quickly as you can until the bubbling has stopped.
Add in the butter and whisk again until it is completely melted.
Sprinkle in the sea salt and mix through.
Careful pour the mixture into a clean jar, pop the lid on and place it into the fridge until it is completely cool.
To Make the Cake
Preheat the oven to 180C (160C Fan). Line two 8” cake tins with greaseproof paper and leave it to one side.
Peel and core the apples and place them into a large bowl. Add in the 40g of light brown sugar and cinnamon and mix until the apples are completely coated. Leave to one side.
In a large bowl, whisk together the sugar and butter until light and fluffy.
Add in the flour, eggs, vanilla extract, and baking powder. Whisk until all the ingredients are combined.
Fold through the apples.
Pour the mixture into the individual cake tins and bake in the oven for 35-40 minutes. You will know they are ready when they are springy to touch.
Leave them to cool in the cake tin for 15-20 minutes and then remove and put them on a wire rack to cool fully.
To Make the Buttercream
Beat the butter in your bowl for 5-10 minutes until pale in colour.
Add in the icing sugar and caramel sauce (optional) and mix until completely combined.
If the buttercream is too thick, add a tablespoon of milk and mix again. Repeat until the buttercream is the desired consistency.
Pop the buttercream into a piping bag with your piping tip and leave to one side.
Putting it All Together
Place your first cake onto your serving plate and pipe on the buttercream.
Drizzle over the salted caramel sauce. If the sauce is too thick to drizzle put it into the microwave for 10-20 seconds to soften.
Place your second cake on top and pipe the buttercream on.
Drizzle over the Salted Caramel Sauce.
Sprinkle over some crumble and enjoy!
