Hi guys i'm a newbie so just wanted to say hi to you all, and i have a question about my victoria sponges that i have been making  recently now the issue is the cream filling keeps spilling out down the side of the cake onto the stand it is on. I have tried to make the cream thicker, i make sure the sponges are cold before putting the jam and cream in, i have tried putting the jam on the bottom sponge first then the jam on top and vice versa, but the cream filling comes out, and when i say comes out i don't mean i have overfilled it and as i put the top sponge on it pours out, what happens is i put the filling (jam and cream)on the bottom sponge and at first the cake looks great but within 10-15mins the cream starts to fall out a little bit at a time, any advice would be most welcome.

I have only just started baking cakes in the last month and its only for my wife and daughter as i had some spare time and the first Voctoria Sponge never had this issue i just cant see im doing anything different, except i have changed the butter from stork to a cheaper supermarkets own brand.

Are you using whipping cream or double cream? If it's whipping cream that could be the issue - less fat content makes it "weaker"....

Or are you using a buttercream type filling?

AAre you using heavy whipping cream? IF yes, then is it just heavy whipping cream and sugar powder? The cake layers might be too heavy for this kind of filling.
