Here is a great idea for a date night treat published on a blog I sometimes read...

A quick desert for two entitled ~ 5 MINUTE CHOCOLATE MUG CAKE

I suggest you add vanilla ice cream and 2 spoons put in a rented or owned video for a simple date night idea, and you don't even have to leave the house (which for me right now is a given... cause I can't even stay out of bed for an hour at a time yet)... it may not be everyone's idea of great but it struck me as a winner!
