Beccy (bless!) unwrapped cracknel - oddly a Lancs speciality (6,4)

I believe the answer is:

eccles cake

I'm a little stuck... Click here to teach me more about this clue!

'a lancs speciality' is the definition.
I can't judge whether this definition defines the answer.

'beccy bless unwrapped cracknel oddly' is the wordplay.
'beccy' becomes 'ecc' (I can't justify this - if you can you should believe this answer much more).
'unwrapped' indicates the central letters (the letters which wrap the word are removed).
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
The centre of 'bless' is 'les'.
The alternating letters of 'cracknel' are 'cake'.
'ecc'+'les'+'cake'='ECCLES CAKE'

Can you help me to learn more?
