What candy looked like a peanut that was crunchy on the outside but had Nutella type chocolate inside?

The candy you're describing sounds like "Raffaello," which is a product of Ferrero. It features a crunchy, coconut-covered exterior with a creamy hazelnut filling inside, reminiscent of Nutella. While it doesn't look exactly like a peanut, its shape and texture can evoke that imagery. Another possibility could be "Ferrero Rocher," which has a similar crunchy exterior and a rich chocolate and hazelnut center.
