I need to make a cheesecake without eggs and sour cream am i able to do so?

This is a tasty vegan cheesecake that everyone should like. http://www.allysonkramer.com/2011/09/apple-pie-cheesecake/

I would Google vegan cheesecake (to ensure that it is eggless); here is a GF, vegan version: http://chocolatecoveredkatie.com/2014/04/01/bake-cinnamon-swirl-cheesecake/

Yes, you can make a no bake cheese cake. I've seen recipes that use gelatin and whipped cream. Just google no bake cheesecake or eggless cheesecake. The sour cream is optional but does add a nice tang which you could get with a little lemon juice or buttermilk.
