Food safety: fruit cobbler edition

Louisiana Dish Fry brand cobbler mix. You mix it with some milk and melted butter. Add a can of fruit to it and bake. It’s basic, simple and decent. Good for how long in the fridge? 10 days? 2 weeks? As long as you don’t see anything growing in it? How long would you think it would be safe?

For the record, it’s gone. Not good enough to eat if there’s even a hint of a question about if it’s still good.
