'By the Seaside' Cake - Horse themed

This cake was mainly designed for a competition where a cake had to be baked that was horse-themed. I decided to decorate a simple one-tiered victoria sponge cake as a beach and added on miniature toy model horses to fit the category!

Ingredients:
Miniature model horses (edible or non-edible)
200g butter
200g icing sugar
Blue food colouring

**please note more or less icing may need to be made depending on the size of the cake**

Method
1. Mix the butter and the icing sugar together to create the butter icing.
2. Roughly split the butter icing mixture in two and add blue food colouring to one of the mixtures until the desired shade is achieved.
3. Smooth the non-coloured, sandy coloured buttercream onto the cake first, only covering roughly one half to two thirds of the cake.
4. On the remaining parts of the cake with no icing, use the blue icing for the sea.
5. More blue icing can be layered up to create the effect of waves.
6. Decorate with the horses as necessary (optional!)
