Can you make buttercream with unsalted Blue Bonnet without compromising the taste? The price of the fancy unsalted butter is BANANAS
Blue Bonnett is margarine and not real butter. It has zero trans fat. Maybe you could add a little butter flavoring to it if you are looking for the butter taste.
Here is a link to another thread on CC about it.
Blue Bonnet is made with oil and water. I wouldn't use it to make frosting.
