Probably my all-time favorite cookie (and cookie dough).  I can’t count the number of times where I’ve just stood in front of the mixing bowl, waiting for a batch of monster cookies to finish in the oven, just taking spoonful upon spoonful of the dough.  One time I did make this into a slice-type thing – I had a craving for baking, and a little of the dough, but didn’t want to have the amount I usually had so I wanted to put it all in the oven at once.  Took about double (or triple) the baking time in a slice pan, but when I cut the pieces and handed them around at a workplace I went to the following day (so we didn’t have them lying around the house), they were a huge success.  My son, Henry, also used this recipe to make a giant monster cookie for his teacher for a Christmas present – worked really well.

Couple of points:

  • Be careful when you add the oats, as the mixture is very ‘gluggy’ and the motors on some hand beaters just cannot handle the thickness (speaking from experience!).
  • You can substitute any ‘pieces’ you wish in this recipe – I often use a combination of milk chocolate, white chocolate and M&Ms, but have used raisins, peanuts, butterscotch pieces, peanut butter pieces, and rice crispies (or some sort of puffed rice) with equal success.
