I made a 3:1 white chocolate ganache yesterday, and allowed it to sit overnight. Today, the ganache was peanut butter consistency, and perfectly thickened. Well, I whipped it for a few moments, and now it seems to be way to soft! It is now more of a whipped cream consistency. I firmed it up for a few minutes in the fridge before I filled and frosted my cake, but as I have had past problems with buttercream bulges in my cakes, I pressed down on the cake when filled, and a ton of ganache squeezed out. This cake is due on Saturday, but this is my first time working with ganache, so I thought it best to work way ahead...
I plan to wait until tomorrow morning, and cover my cake with fondant and monitor for several hours. If there are bulges. I will definitely scrape off and use buttercream instead. But in the meantime. what could have gone wrong? Was it the whipping?
