we are finally on our last batch of

 Grape Nut muffins.  I had a large box of it and substituted it for All Bran in the original recipe.  We've decided that we like them better as they have the chewy pieces in them.

If I understand my scribbled note correctly, when I doubled the the recipe I added 4 more cups of milk.  Which means that if I follow the recipe on the card, I add two more cups of milk.

It is kind of bad when when you can't decipher your own scribbles.
