I got request to make it vanilla bean cake with chocolate and caramel filling also peanutbutter

The cake has to be frosted in a tan color i thought why not do a peanut butter frosting instead as a filling.

I have a great chocolate PB frosting, if I omit the chocolate think that would work?

I am so interested in seeing what this thread brings on. I desperately need a great tasting crusting peanut butter frosting. I have an incredibly deliscious PB frosting recipe, but it's so high fat that it doesn't remotely crust. Please, does anyone have a PB frosting that tastes great and also crusts??????????????????/
