- For the chocolate cake add all the ingredients into your mixing bowl together. If you have eggs on the larger side you may with to hold back a small amount of milk until you can see the consistency. 
- Either with a stand mixer or using a hand whisk combine all your ingredients. You are looking for a smooth mixer which is spreadable, but not too runny. If your mixer is quite thick you can add the rest of the milk. 
- Split your mixture between 2x 6 inch cake tins. I like to add butter around the edge of my tins and dust with flour before adding a 6 inch disc of parchment paper into the bottom, so my cake won’t stick. Once the mixture is added smooth it out on the top. 
- Add your tins onto the middle shelf of a preheated oven at 180°C or 356°F for around 45 minutes. I always use a normal oven setting as I find fan ovens can bake the outside of the cake quicker than the inside. If you only have a fan oven you will need to reduce the temperature and bake for longer. 
- Remove the cakes from the oven when you are able to push a cocktail stick into the center and it comes out clear. 
- Leave your cake to cool before dividing each cake into 2 layers to give you 4 layers in total. 
- For the buttercream add all the ingredients into a clean mixing bowl, making sure to sift the icing sugar to get rid of any lumps. 
- Mix the buttercream in your stand mixer or using a hand whisk for around 5 minutes until smooth and creamy. 
- Once you are happy with the consistency of your buttercream it is ready to use to fill the layers of your cake.
