Bake gingerbread people together - get cutouts for both gingerbread girls and boys and decorate them to look like your sweetie! Use mini frosting tubes, lollies, whatever you can find to make them in a likeness!
I always bake with my kids, but never just hubby and I... great idea! We'd finally get to eat cookies that haven't had grotty little fingers stuck in the batter first! lol
