This recipe is one of my favorites. The Bavarian can be substituted for another but whichever Bavarian cream you use, use it at 1% lower than you would use it at as a single flavor. Like flavour art I use at 2.5% but I would change that to 1.5% in this recipe. Fuji app can be substituted for whatever and leave the% the same unless it's flavour art then drop it to 2%. Besides that leave everything else the same especially the flavor west marshmallow because it has that marshmallow fluff taste (the stuff in the jar) and that's what this recipe calls for
