Seems like a lot of people have recorded this song. It may well be Larry Penn's "Greatest Hit."

Here are the lyrics from John McCutcheon's Website, https://www.folkmusic.com/lyrics/im-little-cookie

I'M A LITTLE COOKIE
(Larry Penn)

E
I'm a little cookie, yes I am
A
And I was made by the cookie man
E
And on my way from the cookie pan
E7 A
A little piece broke off of me
E
A little piece broke off of me, uh-huh
A A7
A little piece broke off of me, uh-huh
D (Dm) A F#7
But I can taste just as good, uh-huh
B7 E7 A
As a regular cookie can

I'm a little chocolate bar, I am
And I was made by the chocolate bar man
And on my way to the chocolate stand
I got a little bend in me
I got a little bend in me, uh-huh
I got a little bend in me, uh-huh
But I can taste just as good, uh-huh
As a regular chocolate bar can

I'm a little tootsie roll, yes I am
And I was made by the tootsie roll man
And on my way from the tootsie roll land
I got a little twist in me
I got a little twist in me, uh-huh
I got a little twist in me, uh-huh
But I can taste just as good, uh-huh
As a regular tootsie roll can

I'm a little gum drop, yes I am
And I was made by the gum drop man
On my way from the sugar can
I got a little dent in me
I got a little dent in me, uh-huh
I got a little dent in me, uh-huh
But I can taste just as good, uh-huh
As a regular gum drop can

Oh, I'm a little cookie, yes I am
And I was made by the cookie man
And on my way from the cookie pan
A little piece broke off of me
Now I ain't as round as I might be
But I taste good just wait and see
And I can love back twice as hard
As a regular cookie can
