You can hear this entire song at WFMU's web site.

I checked the lyrics carefully against the recording and made a few corrections:

CUP CAKES
As sung by Terry "Cupcake" O'Mason

He liked to nibble on my cupcakes.
He just went nuts about their taste.
They seem to melt right in his mouth.
I've never had complainers.
They're smooth as silk and filled with milk,
And he says they come in such cute containers.
Ooh, you should see my lovely cupcakes.
They are much too nice to go to waste.
I asked him if he'd like a bite,
And now he bites them every night.
He likes to nibble on my cupcakes.

He likes to nibble on my cupcakes.
Just like his mother's, they're just right—and left.
They're not too big. They're not too small.
They fit right in his grip.
They're not too hard and not too soft,
And there's a raisin on each tip.
Ooh, you should see my lovely cupcakes.
They made him raise a hear—ty appetite.
They're juicier than any steak,
And he found out that they weren't fake.
He likes to nibble on my cupcakes.
