This sort of gets off the topic of solder, but others explained that
fairly well. however I imagine they fill the candy the same way jelly
filled donut (sweet rolls) are filled. I once asked a baker how they do
it, and he said it's injected with a device similar to a syringe. A
plastic point is shoved into the donut and the jelly injected.

A large object like a donut or candy seems a lot more easy than that
thin solder.
