Are you wanting to make a proper cake or would something like a cheesecake suffice? Cheesecake would be the easiest and those tend to taste normal even to someone not doing atkins. You can always top it with fresh fruits if you are out of induction too. Here is a link from the atkins site for dining out on indian foods

I love saag / palak paneer (spinach with the cheese) unfortunately the link lists mostly meat stuff but there were at least a couple ideas on it. Have a great night with your partner.
