My boss makes this really delicious candy around the holidays.  She shared her recipe with me :-)
Ingredients:
1 cup Butter (no substitutes)
1 cup Brown Sugar
1 tsp oil
Saltine Crackers
1 bag of Semi-Sweet Chocolate Chips
Preheat  oven to 350 degrees. Line a cookie sheet with aluminum foil.  Spread  oil on aluminum foil.  Lay one layer of saltines to cover pan (I prefer  salt side down).  In a saucepan melt butter, add brown sugar and bring  to a boil.  Boil for 2 minutes (should get foamy - don't over-stir).   Pour over crackers.  Bake for 5 minutes at 350 degrees. Sprinkle entire  back of chocolate chips on top.  When melted spread evenly.  Let cool  (we usually put in the fridge).  Break in small pieces to serve.
