Follow the instructions for the Betty crocker cake mix and place mixture in two separate 8 inch round tins. Cook for desired time as stated on packaging. I baked it for around 25 mins.

Once cool, melt the butter, chocolate, milk and icing sugar and spread around the cake and inside the cake. 

Make the holly leaves. I used white roll out icing, and added a splash of green colouring and mixed it in, but you can buy green roll icing. I had holly leaf cutters already, but you could make them yourself, it will just be more time consuming!

Keep in fridge. Enjoy!
