HOW TO MAKE A PEANUT BUTTER ICEBOX CAKE, STEP BY STEP:
- Add the vanilla pudding mix, peanut butter, and 1 cup of the milk into a large bowl.
- Using an electric hand mixer, whip until smooth.
- Slowly add two more cups of the milk and whisk until completely smooth.
- Fold in 8 ounces of whipped topping until no streaks are left, set aside.
- Place nutter butters into the bottom of a 9×13-inch baking dish. Five across in four rows.
- Brush the milk generously on each cookie. You really want to soak them.
- Add ⅓ of the pudding mixture and spread it out evenly over the cookies.
- Add another row of cookies and brush with milk.
- Then, add another ⅓ of the pudding mixture and smooth it out.
- Repeat 1 more time.
- Add a final layer of cookies brushed with milk.
- Spread the remaining whipped topping over the cookies.

- Drizzle the peanut butter over the cake and add more cookies if desired. Slice and serve.
IS THIS REALLY PEANUT BUTTER FORWARD?
This is a peanut butter explosion, if you want a little less peanut butter punch then omit the peanut butter in the pudding mixture.
But if you absolutely love peanut butter like we do, then keep it the way it is!
CAN I ADD ANY ADDITIONS TO THE PUDDING MIXTURE?
Yes! If you want to switch it up a bit you can add things like mini chocolate chips, toffee bits, chopped nuts, white chocolate chips, reese’s pieces, etc.
There is a lot of different flavors that would mesh well with this recipe, even drizzling with some chocolate instead of peanut butter would be amazing.
HOW LONG DOES THIS NEED TO CHILL?
While I said that this is the hardest part, since you really do not want to wait to eat it, it is a necessary evil.
This needs to sit for at least 8 hours or overnight, or longer if possible. It needs time to soak into the cookies and soften them.
CAN I USE CRUNCHY PEANUT BUTTER?
If you want a little more texture and crunch to this recipe you can absolutely use chunky peanut butter in this Peanut Butter Icebox Cake.
HOW TO STORE:
This can be stored covered in the refrigerator where it will keep for up to 5 days.
You can also freeze this Peanut Butter Icebox Cake. Wrap tightly in plastic wrap and then foil and it will keep in the freezer for up to 3 months.
To defrost, remove to the refrigerator until thawed, or you can cut it directly from frozen as well.
