Chocolate would normally be melted at body temperature, no?

she can minipulate time maby thats why its warm but holds it shape

The translator left out the part where she says it's a "Belgian chocolate bun", rather than just Belgian chocolate. If it's in a bun, it wouldn't leak out.

Fixed.

That explains it!

It's actually written as ベルギーチョコまん. And the まん is like a suffix behind that says 'bun'.
肉まん、あんまん。
And all sorts of まん.
