Found it on the website, here's the recipe. Grandma's Tasty Dinner
Ingredients:
1 pre-made chocolate cookie pie crust
1 (8 oz) container whipped topping (Cool Whip), thawed
¾ cup creamy peanut butter
½ cup melted chocolate chips
Directions:
In a mixing bowl, combine the peanut butter with half of the whipped topping and mix until smooth and creamy.
Gently fold in the remaining whipped topping until the mixture becomes light and fluffy.
Spoon the peanut butter mixture into the chocolate cookie pie crust and spread evenly.
Drizzle the melted chocolate over the top of the pie.
Use a knife or skewer to gently swirl the chocolate into the peanut butter filling for a marbled effect.
Smooth lightly while keeping the swirl visible.
Refrigerate for at least 4 hours, or until the pie is fully set and chilled.
Slice and serve cold for a rich, creamy, and airy dessert experience.
