I want to make a cake that involves a brownie layer with chocolate mousse on top. I just want to use my own trusted brownie and chocolate mousse recipes. I've looked it up and found a few similar recipes.
Now, I'm worried that the chocolate mousse might have a bit of fluids at the bottom that will ruin the brownie layer. Is there anything I can do to improve this (I was thinking of a small layer of chocolate that will prevent absorption of the fluids by the brownie) and is it generally a good idea to combine the two or am I better off making a regular chocolate cake layer instead of a brownie?
Thank you for your advice
