how to make gummy-mallow hybrid?

I’ve eaten a lot “gummy burger” recently.

It’s not really a gummy, but a hybrid of marshmallow and gummy. When I look for the recipe in internet, there’s marshmallow recipe and gummy recipe, but none of them look like this one:

Does anyone know how to make it? Any advice is welcome!
