Line a 9x9 baking dish with parchment paper, set aside.
Using either a stand mixer or a hand held mixer, combine the melted butter, powdered sugar and graham crackers.
Mix in the 1 ¼ cup of creamy peanut butter, just until well incorporated.
Evenly spread the peanut butter mixture into the bottom of the baking dish.
In a heat safe bowl, add the semi sweet chocolate chips and the remaining 3 tablespoons creamy peanut butter. Heat for 30 second intervals, stirring well after each interval until the peanut butter and chocolate are smooth.
Spread the chocolate mixture over the peanut butter base.
Chill the bars for 1 hour.
Let the bars sit 10 to 15 minutes, at room temperature, before serving.

Notes
STORAGE: To Store: Any leftovers should be stored in an airtight container in the fridge for up to 1 week. This helps them keep their shape better.To Freeze: Cut the bars into individual squares and either place parchment paper between each one or wrap each one individually. The bars will keep for at least three months in the freezer.TIPS:
If you use unsalted butter, add a pinch of salt into the peanut butter mixture.
To slice, remove from the refrigerator and let them sit out for about 10 minutes. Run a sharp knife under very hot water and carefully slice.
