These are so good and it firms up very quickly. They have the texture of soft fudge and I add 1/2 cup of cut up marshmallows.

I tried it with four packets of gelatine. It was firm and fudgy-like. I then tried it with two packets of gelatine and it was more jiggly like jell-o, still able to hold up really well if using a mold.
