Step 1

Place the graham crackers in a food processor and mix into a fine powder.

Step 2

In the microwave, melt the butter WITH 1 1/2 cups of peanut butter.

Step 3

In a large bowl, add the butter and the 1 1/2 cups of peanut butter that you just melted. Add the graham crackers, confectioners' sugar, salt and mix well.

Step 4

Line a 9x13 inch pan with parchment paper. Pour the mixture into the pan and spread evenly.

Step 5

Place in the refrigerator for 20 minutes.

Step 6

While the bottom layer is chilling in the refrigerator, prepare the top layer.

Step 7

For the top layer, melt the chocolate chips with 4 tablespoons of peanut butter in the microwave. Stir occasionally until smooth.

Step 8

Spread the melted chocolate over the prepared crust. Refrigerate for at least one hour before cutting into squares. This prevents the chocolate topping from cracking.

Step 9

Enjoy!
