I just finished making a teapot cake filled and covered with ganache then MMF and also i made Halloween cupcakes with ganache and MMF too. Before I will hit the sack I'd like to ask if it is ok to leave my cake with ganache and MMF in room temp? or Should I put this in the fridge? TIA hope you all will reply really soon. Im afraid of spoilage since ganache is made with cream .

ganache can be left out because the cream has been cooked....
