Hi all! Long time observer, first time writing. My MIL's birthday is this weekend and she has requested I bake her birthday cake alternative - my peanut butter chocolate fudge brownies (normal brownies, layer of smooth peanut butter, topped with tempered dark chocolate.) I'd like to do the traditional birthday message-y stuff on top, but I think piped icing would not go with the taste of the goodies, so i'm thinking about using tempered white chocolate instead. Problem is, i've never piped with chocolate before! I think it's a lot less thick than the icing i've used to write with before, and I haven't had the most successful time with it anyway. Any tips on how I can pull this off? Even cheats would be appreciated!
