Start by crushing the chocolate graham cracker sheets into fine crumbs. You can use a food processor or place them in a zip-top bag and crush them with a rolling pin. In a mixing bowl, combine the graham cracker crumbs with granulated sugar and melted butter. Stir until the mixture resembles wet sand.
Press the graham cracker mixture firmly into the bottom and up the sides of a 9-inch pie dish. Make sure it’s evenly packed to create a sturdy crust. Place the crust in the refrigerator to chill while you prepare the filling.
In a large mixing bowl, beat the cream cheese until smooth and creamy. Gradually add the powdered sugar while continuing to mix. Once combined, add the peanut butter and mix until fully incorporated.
Gently fold the Cool Whip into the cream cheese mixture using a spatula. Be careful not to deflate the whipped topping; you want to keep it light and airy.
Chop 3 Snickers bars into small pieces and fold them into the filling mixture. This will give your pie delightful chunks of caramel and peanuts throughout.
Remove the graham cracker crust from the refrigerator and pour the filling into the crust. Spread it evenly with a spatula. Chop the remaining 2 Snickers bars and sprinkle them on top for garnish.
Cover the pie with plastic wrap and place it in the refrigerator for at least 4 hours, or overnight if you have the time. This step is crucial for the pie to set properly.
Before serving, drizzle chocolate and caramel syrup over the top and sprinkle chopped peanuts for an extra crunch. Slice, serve, and watch your guests swoon over each bite of this Snickers Bar Pie!
