I am making a lemon vanilla swirl cake and i wanted to put some lemon pie filling in the middle of the two layers. But the last time i tried something like this, it exploded out the side. I piped a dam of stiff buttercream around the edge of the cake but maybe I did it wrong...I don't know. Any advice would be greatly appreciated! THANKS! : )

Try using less filling.

Placing buttercream in a few places inside your dam will help hold up the top layer and keep it in place

Could your buttercream have been to stiff to stick to the cake?
