INSANE! This juice box kids birthday cake has actual juice inside!

Would your child love a cake that serves actual juice inside it for their next birthday cake?

This giant cake, from American cake maker Yolanda at How To Cake It is a genius idea as it can actually hold liquid inside it so you can serve it at the party! 

But unsurprisingly it isn't easy and you'll need 9kg of cake mix to make it work. Yes, that's 9kg of cake batter!

The cake is built up around a juice container and then filled with juice before the top is sealed with yet more cake!

After studying the video, we've concluded it isn't one for beginners cake-makers, and you'll need an entire day and plenty of eggs to get started!
