Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter adds delightful texture to the pudding layers. Just be aware that it might be slightly more difficult to spread evenly, but the extra peanut bits add wonderful crunch throughout the cake.

My pudding isn't setting up properly. What went wrong?

The most common issue is using non-dairy milk. This recipe needs cow's milk for the pudding to set correctly due to the proteins in dairy milk. Also, make sure you're using instant pudding, not the cook-and-serve variety, and allow enough time for it to thicken before adding other ingredients.

Can I make this dessert healthier?

While this is definitely an indulgent treat, you can make some adjustments. Try reduced-fat versions of the pudding mix, milk, and whipped topping. You could also use natural peanut butter with less sugar, though the texture may be slightly different.

How far in advance can I make this icebox cake?

This cake is perfect for making ahead! You can prepare it up to 2 days before serving. In fact, many people find the texture improves after 24 hours in the refrigerator as the cookies soften completely and the flavors meld together.

How to Make No Bake Peanut Butter Icebox Cake

Step 1: Prepare the First Cookie Layer

Pour 1/2 cup milk into a small bowl. Quickly dip about one-third of the peanut butter cookies in the milk and arrange them in a single layer at the bottom of an 8×8″ baking dish. Don’t soak them too long – just a quick dip does the trick!

Step 2: Create the Peanut Butter Pudding Mixture

In a large mixing bowl, whisk together the remaining 1¼ cups milk with the instant pudding mix until smooth. Let it sit for about 2 minutes until it begins to thicken. Once set, stir in the peanut butter until completely incorporated, then fold in half of the whipped topping. This creates an irresistibly creamy peanut butter mixture.

Step 3: Build the Layers

Spread half of your peanut butter pudding mixture over the first cookie layer. Dip another third of the cookies in milk and create a second layer on top of the pudding. Follow with the remaining pudding mixture, then dip and place the final cookies on top.

Step 4: Add the Finishing Touches

Spread the remaining whipped topping over the final cookie layer, creating a smooth, even surface. Generously sprinkle Reese’s Pieces over the top for that perfect finishing touch of color and flavor.

Step 5: Chill and Set

Cover loosely with plastic wrap and refrigerate for at least 2 hours, though overnight is even better. The magic happens during this time as the cookies soften into cake-like layers and the flavors meld together beautifully.

Pro Tips for Making the Recipe

Quick Dip: When soaking the cookies, a brief dip is all you need – about 1-2 seconds per cookie. Too long and they’ll fall apart!
Smooth Spreading: Use an offset spatula for perfectly even layers that look as good as they taste.
Patience Pays Off: While two hours of chilling is the minimum, letting it sit overnight takes this dessert to a whole new level of deliciousness.
Room Temperature Peanut Butter: Using room temperature peanut butter makes it much easier to incorporate into the pudding mixture without lumps.

How to Serve

This No Bake Peanut Butter Icebox Cake is versatile when it comes to serving options:

As a Dessert:

Serve chilled with a cold glass of milk for the ultimate peanut butter experience. Cut into squares and watch them disappear!

For Special Occasions:

Dress it up with a drizzle of warm chocolate sauce and a dollop of extra whipped cream for birthdays or celebrations.

With Ice Cream:

A scoop of vanilla ice cream alongside a slice of this cake creates a dessert that’s truly over the top.

Make Ahead and Storage

Storing Leftovers

Cover any leftover cake loosely with plastic wrap and store in the refrigerator for up to 4 days. The flavors continue to develop, making day 2 or 3 potentially even more delicious than day 1!

Freezing

If you’ve used store-bought whipped topping, this cake freezes beautifully. Cover tightly with plastic wrap and then aluminum foil, and freeze for up to 1 month. If using homemade whipped cream, freezing isn’t recommended.

Reheating

No reheating necessary! Simply thaw frozen cake in the refrigerator overnight before serving chilled.
