I am using milk chocolate ganache as my crumb coat and filling but also want to use a fruit filling. I don't feel like cutting my cakes into thinner layers so I am only going to have one middle section for a filling. Can I spread ganache (making it thicker around the edges-creating a dam) and then put some filling on top? Seems like I could...just wonder if anyone has ever done that before.

I want to do this because my fiance loves ganache and wants it used as filling. I want to add some fruit but no extra layers.

In case it matters, I am using Polaner All-Fruit with a bag of Jello to mixed in. If you haven't ever heard of this tip it's awesome. Heat (sans lid) a jar of Polaner, put into a bowl, add same flavor Jello powder, mix well. It helps the filling to firm up.

I don't see any good reason why you couldn't do that.
