Can you use a ganache as a cake filling?

lolz! i missed the ' in the husband.. i meant husband's favourite...

Definitely! If you do not want to chill it you can place the ganache bowl into ice bowl..i mean a bowl full of ice to thicken it on the spot.. I make Choc fudge cake with ganache everytime ..its my husbands favourite..i would like to attach a picture..also..

For sure! And when you do, send it my way.

Absolutely! I make a chocolate cake with a ganache frosting every year for a friend's bday. It's her only request:).

After you make the ganache, chill it for 24 hours in the fridge. It should become very thick. Take out of the fridge 30 min or more before frosting. Enjoy!!!!!

Do I just make the ganache as the receipt say or is it to be thicker?

Yes!
