I had read somewhere on here that you can add chocolate pudding and milk to Bettercreme. I know you don't have to refrigerate Bettercreme but if you add the milk to it, does that mean it must be refrigerated?

Why would you add chocolate pudding? They sell chocolate Bettercreme.

The only place I can find it local is GFS and they only sell the vanilla

What about choc pudding and water??

I've used bettercreme from previous post using a chocolate syrup to make it choclolate and I must say it was absolutely wonderful. Don't remember reading about adding chocolate pudding. That's new! To find the old post you may want to google: cake central-bettercreme frosting.

Try the "Bettercream Fun" thread. Melvira has several suggestion for toppings and fillings that use Bettercream as their base. It's in the cupcake forum.
