Any ideas for using up sour cream?

[Ida Red]

I want to make a dessert for a BBQ today, but I don't want to shop.
Main ingredients I have is a ton of sour cream, chocolate, nuts, maple syrup, lemons, oranges, grapefruit, and all the basic baking stuff.
I do not have cream cheese, ruling out cheesecake nor do I have heavy cream, but I do have milk.
Any ideas out there? I'm thinking of some kind of a bundt cake, but I kind of would rather bring some kind of a bar-type dessert.

If you have all the ingredients....go for lemon coffee cake!
