Want to create a non - chocolate molten lava cake, ideas and advice please

Was thinking of a cheese lava,
Possible method 1) cream cheese, yogurt, xanthan gum
Possible method 2) cream cheese, yogurt and agar. Use the agar to to firm the cream cheese and yogurt. Then when baking, the heat from the oven will cause the agar to dissolve so cheese flows.

Will any of these method work? How much of each ingredient? , temperature to bake at? How long? Any other ideas?
Thanks guys and gals
