Grandmas Icebox Cake: How It’s Done

Creating Grandmas Icebox Cake is a breeze. Follow these simple steps for a dessert that will impress everyone.
Step 1: Prepare the Pudding
In a mixing bowl, combine the instant vanilla pudding mix with the 6 cups of milk. Whisk together until the mixture thickens, usually about 2 minutes. This will create a smooth and creamy pudding base that is the heart of your icebox cake.
Step 2: Layer the Ingredients
In your 9×13 inch baking dish, start by spreading a layer of the prepared pudding mixture at the bottom. This will act as the first layer of your cake.
Step 3: Add Graham Crackers
Next, take your graham crackers and arrange a layer on top of the pudding. Break the crackers if necessary to make them fit snugly in the dish.
Step 4: Repeat the Layers
Continue alternating layers of pudding and graham crackers until you run out of ingredients. The final layer should be pudding, so make sure to save enough for the top of the cake.
Step 5: Spread the Cool Whip
Once your layers are complete, take the Cool Whip and spread it evenly over the top layer of pudding. This adds a light and fluffy finish to your Grandmas Icebox Cake.
Step 6: Chill in the Refrigerator
Cover the dish with plastic wrap and place it in the refrigerator. Allow it to chill for at least 4 hours, but overnight is even better. This resting period lets the graham crackers soften and meld with the pudding, creating that signature icebox cake texture.
Step 7: Serve and Enjoy!
Once chilled, slice your Grandmas Icebox Cake into squares and serve. Enjoy the creamy goodness and the delightful crunch of the graham crackers!
Low-Carb/Keto Alternatives

If you’re looking to make a low-carb or keto version of Grandmas Icebox Cake, consider these substitutions:
- Low-carb vanilla pudding mix: Look for sugar-free or low-carb options to replace the instant vanilla pudding mix.
- Almond milk: Substitute regular milk with unsweetened almond milk for fewer carbs.
- Keto graham crackers: Use a low-carb graham cracker alternative or make your own using almond flour.
- Whipped cream: Consider using homemade whipped cream sweetened with a sugar substitute instead of Cool Whip.
These alternatives will help you enjoy the classic flavors of Grandmas Icebox Cake without the extra carbs.
Mistakes That Ruin Grandmas Icebox Cake
Even though Grandmas Icebox Cake is easy to make, there are still a few common mistakes you should avoid to ensure your dessert turns out perfectly:
- Not letting it chill long enough: Skipping the refrigeration step can result in a soggy texture. Be patient and let it set!
- Using regular whipped topping: Stick to Cool Whip for the best results. Homemade whipped cream, while delicious, can deflate and affect the final texture.
- Overmixing the pudding: Whisk just until combined; overmixing can create air bubbles that affect the pudding’s consistency.
- Not breaking the crackers: Ensure the graham crackers fit well in the dish. Break them as needed to prevent gaps between layers.
Avoiding these pitfalls will help you create a flawless Grandmas Icebox Cake that everyone will rave about!
Refrigerate, Freeze, Reheat
To keep your Grandmas Icebox Cake fresh and delicious, consider these storage tips:
- Refrigerate: Store any leftovers in an airtight container in the refrigerator for up to 4-5 days.
- Freeze: You can freeze the cake for up to 2 months. Just be aware that the texture may change slightly after thawing.
- Reheat: There’s no need to reheat this dessert; it’s best enjoyed chilled straight from the fridge!
These storage tips will help you enjoy your icebox cake for days to come.
Reader Q&A
Can I use a different flavor of pudding mix?
Absolutely! While vanilla is classic, feel free to experiment with chocolate, butterscotch, or any flavor you love. Just keep the same proportions!
Can I use homemade whipped cream instead of Cool Whip?

How long does Grandmas Icebox Cake last in the fridge?
Your cake should stay fresh for about 4-5 days when stored in an airtight container in the refrigerator. Just be sure to check for any signs of spoilage before enjoying leftovers.

Yes! In fact, making it a day in advance is ideal. It allows the flavors to meld and the graham crackers to soften perfectly.
