Step 1

Line an un-greased 9x13 inch baking pan with parchment paper, leaving an overhang on either end. 

Step 2

Line the parchment paper with one layer of club crackers, cutting them to fit if necessary.

Step 3

In a large saucepan, melt butter over medium heat. 

Step 4

Add graham cracker crumbs, brown sugar, granulated sugar and milk. Stir well and bring mixture to a boil — boil for 5 minutes, stirring constantly. (Begin timing 5 minutes from when you see the first bubbles.) 

Step 5

Remove from heat and spread half of the mixture over crackers and gently smooth it into an even layer. 

Step 6

Place another single layer of crackers over the top, cutting to fit if necessary. Spread remaining mixture evenly over crackers. 

Step 7

Top with one more layer of crackers. Set aside.

Step 8

In a small saucepan, combine peanut butter, chocolate chips, and butterscotch chips. 

Step 9

Melt over medium-low heat, stirring constantly, until smooth. Spread evenly over top of crackers.

Step 10

Chill for at least 1 hour. Remove from fridge and allow chocolate to rest for a minute or so before cutting. This will help avoid breaks in chocolate as it's being cut. 

Step 11

Pull up on the parchment paper to remove them from the pan. Cut into bars. Store in the refrigerator.
