To create tier 1 (tier 1 is made up of 4 x 6 inch layers)

Dry ingredients:

Wet ingredients:


This creates enough to add a thin layer between each cake and to coat the outside twice. Plus it leaves enough for any decoration.

Chocolate Dripping & Shard


  • 250g marzipan
  • Dr Oetker gold shimmer spray
  • Autumnal food colouring (brown, green & yellow)
  • Handful of chopped hazelnuts *

* Ingredients available at Holland & Barrett

Add all to basket


To make the cake

Step 1.
Add mixed wet ingredients to dry ingredients and combine.

Step 2.
Line a 4 x 6-inch tins with baking paper and pour in the mixture.

Step 3.

Place all 4 tins in the oven and bake for 40-45 minutes at 180°c in a pre-heated oven or until a knife comes out clean when poked into the cake. If the top looks like it might be getting a little too dark then cover with tin foil. Allow it to cool before assembling.
NOTE: If you do not have multiple tins then repeat steps 2 & 3 three more times to create 4 layers.


Step 1:
Beat together the frosting on slow until all the powder has mixed in then beat fast until light and fluffy. Save around 200g should you wish to use the frosting for decoration.

Step 2:
Use the remaining frosting to layer the cakes together. Frost over the whole cake in a thin layer (few mm’s thick) and chill for an hour.

Step 3:
Then go over again with another layer of frosting to give a nice neat finish. With the reserved 200g, colour with green food colouring for any wording you wish to pipe on the cake.

Chocolate Dripping & Shard

Drizzle over the top and allow drips to fall down the sides of the tiers. Top tip: use a piping bag to make the drips neater.

To create the chocolate shard at the top, smooth melted chocolate onto a baking sheet until chilled and then cut desired shape.


Step 1: Acorns
Take the marzipan and mould into teardrop shapes, the size of a large acorn.

Roll out a little bit of marzipan, using icing sugar to prevent sticking, and use a round cutter to make the acorn top.

Place onto the top half of the acorn and use a little tool, such as a toothpick or modelling tool, to make the detail on the top. Then add a little stalk by rolling a little more marzipan. Leave to dry then spray with gold shimmer spray.

Attach to the cake with a little bit of frosting, if required.

Step 2: Leaves
For the leaves, add the food colouring to the remaining marzipan in any autumnal shades you wish. Knead until the colour is an even shade throughout the marzipan.

If you have leaf plunger cutters, roll out the marzipan thinly with a little icing sugar to prevent sticking and use leaf cutters to cut out and make the veining details. If you want to add more detail you can also use a colouring dust to brush over the veins to create darker veins to make them look more realistic.

If you do not have leaf cutters you can simply roll out and use a sharp knife to make various leaf shapes and use the top of the knife to create the veins.

Attach with a little bit of frosting, if required.

Step 3: Hazelnut crumbs
Sprinkle the chopped hazelnuts on the top of the cake and along the bottom edges.
