I'll pile on the candy,
It's such a pretty sight
It makes the food taste dandy
But my tummy hurts all night

But keep the rest for me
I'm not just disobedient
I'm careful, can't you see?

It's a piece of cake to bake a pretty cake
If the way is hazy,
You gotta do the cooking by the book
You know you can't be lazy
Never use a messy recipe,
The cake will end up crazy
If you do the cooking by the book,
Then you'll have a cake
We gotta have it made,
You know that I love cake
Finally, it's time to make a cake!

With tools that blend and baste
And every fun appliance
Gives the food a different taste!

If the way is hazy,
You gotta do the cooking by the book
You know you can't be lazy
Never use a messy recipe,
The cake will end up crazy
If you do the cooking by the book,
Then you'll have a cake
We gotta have it made,
You know that I love cake
Finally, it's time to make a cake
We gotta have it made,
You know that I love cake
Finally, it's time to make a -
