Step 1

Cover a baking sheet with foil or parchment paper and spray with cooking spray. I used an 18 x 13 x 1 inch pan.  You need the lip on the pan to keep liquid from running off in your oven.  Spread the crackers on the pan like in the photo below.  In a pan on top of the stove combine the butter and brown sugar. Bring to a boil on medium heat and then boil for 3 minutes.  DO NOT STIR WHILE BOILING.

Step 2

Remove from stove after boiling 3 minutes and spread over the saltine crackers with a knife. The mixture should be at soft ball stage or should make a soft ball when a little is dropped in ice water.  Have your oven preheated to 400 degrees.  Place baking sheet in oven for 3 minutes on middle rack.  Remove after 3 minutes and sprinkle on chocolate chips.  Put back in oven for another minute to let chocolate chips melt.  Remove and spread out the melted chips with a knife. Sprinkle on nuts and kind of mash into chocolate.  Refrigerate until hard (about 2 or 3 hours) or could put in freezer for a while.  Break into pieces.  Makes a 1 1/2 quart container full.  Keep refrigerated.
