Lightly grease a 9 x 13” inch pan, pour in the corn chips.
In a heavy bottom saucepan, over medium heat, carefully bring sugar and corn syrup to a boil. Remove from heat.
Stir in the peanut butter until smooth. Pour peanut sauce over chips and level out mixture.
Immediately place the chocolate bars in a single layer over the hot mixture and wait a few minutes until they begin to melt. Gently smooth the chocolate out to form a thin layer. Allow to cool and break into pieces.
