Nipples of Venus (Capezzoli di Venere)
If you must, another nut like almond, or hazelnut, should work about the same, especially when you consider your guest, or guests, will be fairly distracted by the eye-opening appearance.
Substitute cognac for the brandy if you prefer.
You can easily make the filling ahead of time, freeze, and add the coating any time.
This is more white chocolate than you need for coating, but that's how this stuff works. Just eat the rest.
