These large, white chocolate puffy hearts are filled with a peanut creme filling. I typically use a good peanut butter mixed with honey, but I noticed that the oils in the pb kept beaking down the chocolate. So, I mixed the peanut butter with a fondant filling and that made it much easier to work with and didn't result in any bad hearts. I make these in milk chocolate as well, and call them Peanutty Hearts.
