I’ve just made these:
Ingredients: pea protein powder, cocoa, ground hazelnuts, sweetened condensed coconut milk, chia seeds, peanut butter … and I think that’s it. I don’t recall the quantities as I just kept adding stuff until the consistency was right and it tasted good.
The sweetened condensed coconut milk I found in a health food store recently and bought a can thinking I might use it one day instead of cow’s condensed milk. It’s really good and I’ll buy it again. You could probably make a savoury version of these peanut butter balls without it but you’d need to add some other liquid instead otherwise they’ll be too dry. You could also use dates for sweetness.
