Welcome to the Cake Decorators Q&A

Can I mixed half dark chocolate and half milkchocolate to make a ganche for my cake filling.

Yes you can. You can also add a nob of butter and a little alcohol liqueur if you want a soft fudgy filling. Once the ganache is made cover it up with cling film so it makes contact with the mixture. This will prevent a skin forming and it will also keep nice and soft. For best results keep at room temperature and use the next day.

Thank you and will give it a go.
