What's missing?

I have taken on a new endeavor this year with my FCCLA group - a holiday bread sale.  We sold four different kinds and will be making them ourselves starting next week.  When I started planning for this a few weeks ago, I decided to have one of my foods classes give the recipes a trial run so the club members would be able to taste the product before the sold it.  The lemon, chocolate, and sour cream streusel loaves all turned out great. 

The problem came with the pumpkin.  Thirty minutes into baking the 10 small loaves they still had not risen like the others and the girls called me over.  This is what I found: 

I began going through the list of ingredients, thinking they had left out the baking soda or baking powder.  Neither was the case.  Any guesses? 

The flour!  The recipe called for 6 cups of flour, and they didn't put in a single one!  I was a very unhappy camper.  Needless to say the board members did not get pumpkin bread that night.  It will take the girls a long time to live this one down. 

Sales have also been pretty successful.  We now have 207 loaves of bread to bake next week.
