Bread-Bakers v098.n011.14

I saw the posts about adding M&M's to a batter.  I have a sister in law
who is nuts over M&M's (especially peanut) pun intended.  We are getting
together in a couple of weeks and I would love to surprise her with a
M&M bread.

Can someone suggest a batter that would be fitting for such a treat? 

I need this by 2/12 at the latest.  So could someone please email
privately if there is a doubt about the timing.  I could post it to the
list after I receive it.

Thank you ever so much

Dave
