Grape nectar baby cakes

I have made several recipes from this adorable little book and loved each and every one of them. Now, Julie Le Clerc strikes again – the cakes are very simple, but the grape syrup... Yum! I bet it tastes great over ice cream, too – too bad there was none left for testing. :D
