Step 1

Lightly grease a 13- by 9- inch pan with nonstick spray. Crush Oreos in a blender then transfer to a medium bowl. Mix in the melted butter and toss to coat. Evenly press into the bottom of the pan.

Step 2

In a medium bowl, combine the peanut butter, powdered sugar and cream cheese until smooth. I use my stand mixer fitted with the paddle attachment, but you can also use a wooden spoon or rubber spatula. Fold in half of the Cool Whip, then spread over the Oreo crust.

Step 3

In another medium bowl, whisk the chocolate pudding mix into the 2 cups of milk. Let stand for 2 minutes to thicken, then evenly spread over the peanut butter cream cheese layer.

Step 4

Spread the remaining Cool Whip over top then sprinkle with the chopped Butterfinger candy bars. Cover with plastic wrap and refrigerate for at least 1 hour before serving. Keeps in the fridge for a few days, but no longer than 1 week.
