Share 'rich creamy fillings without the cream'

I hope there is someone out there who can help me...I am new at the chocolate world and I am looking for a recipie for a smooth rich and creamy filling for chocolates that I can flavour with various flavourings but I do not want to use cream or milk.  I am in Florida and the weather can be very hot and humid therefore I am willing to use butter but am scared of cream turning...is there anyone out…
