Oh my, this was one amazing cake! The apple crumble loaf cake is made using the rubbing in method, the same method that you would use to make your usual crumble topping, and it keeps the cake lovely and moist.

The creamy custard buttercream (and what a revelation that was!), was whipped up in no time in my trusty Kitchen Aid. If you don't have a mixer, don't worry, you can also make it by hand.

For a cake that tasted so good, it really was very simple to make.

Top tips for making the cake

  • If you can't get hold of Bramley Apples, use eating apples but cut the amount of light brown sugar you use in the cake, to 120g.
  • If you haven't got the time or inclination to pipe the buttercream, just spread it in with palette knife.
  • The un-iced cake can be frozen for up to 3 months, as can the crumble topping.

How to make buttercream icing?

Buttercream is super simple to make, especially if you have a mixer, that will do all the hard work for you.

Buttercream is made by combining butter and icing sugar, and usually a little bit of milk, to make it lovely and smooth. Either pop it in your mixer and mix on a medium -high speed, or, roll up your sleeves and beat it together with a wooden spoon. It helps if your butter is very soft (but not melted).

I used salted butter in this custard buttercream icing, which complemented the cakes sweetness really well. Unsalted butter is fine to use, if you only have that.

How long does the cake keep for?

The apple crumble loaf cake keeps pretty well for 4 or 5 days in an airtight tin...but I guarantee it wont last that long!

A Bramley Apple Crumble Loaf Cake with a sweet Custard Buttercream Icing. A classic British pudding in cake form!


  • 140g Butter, cubed
  • 250g Self Raising Flour
  • 1 TSP Mixed Spice
  • 140g Light Muscavado Sugar
  • 3 Eggs, beaten
  • 2 Bramley Apples, peeled and cut into small cubes
  • 5 TBSP Milk
  • For the Crumble Topping:
  • 30g Plain Flour
  • 10g Ground Almonds
  • 25g Butter, cubed
  • 25g Caster Sugar
  • For the Custard Icing:
  • 100g Salted Butter
  • 200g Icing Sugar
  • 20g Custard Powder
  • 30ml Milk


  1. Preheat the oven to 180°c (160°fan) and line a 2lb loaf tin with baking paper, as well as a small baking sheet (for the crumble topping).
  2. For the cake, rub the butter and flour together until you get breadcrumbs, then stir through the mixed spice and light brown sugar.
  3. Beat in the eggs, bramley apples and milk, then spoon into the loaf tin and bake for 55 minutes (or until a skewer comes out clean).
  4. Whilst the cake is in the oven, make the crumble topping. Rub the flour, ground almonds, butter and sugar together until you get a rubble type mixture. Place the mixture onto the lined baking sheet, and put into the oven for the last 30 minutes of the cake baking.
  5. Once the cake and crumble topping are cooling, make the icing. Put the butter and icing sugar into a stand mixer and mix at a medium-high speed until creamy and smooth. Dissolve the custard powder into the milk then beat this in on a high speed. Pipe onto the cooled cake, then sprinkle with the crumble topping.
