Can I make peanut butter ganache? And if so can I put fondant over it?

The only thing I could find was a chocolate peanut butter ganache, it should work under fondant like the regular ganache does. HTH

10 ounces dark or semi-sweet chocolate, finely chopped
¾ C heavy cream
¼ C corn syrup
3 Tbl creamy peanut butter
In a saucepan, combine the cream and corn syrup and bring to a boil
Remove from heat and whisk in chocolate until melted and smooth
Whisk in peanut butter until well blended
