This nostalgic icebox cake brings back summer memories with its creamy layers and fresh strawberries. The classic combination of graham crackers softening into cake-like texture overnight creates a dessert that tastes like it took hours of baking, not minutes of assembly.
I first made this icebox cake for my niece's birthday when the power went out during a heatwave. What started as an emergency dessert solution has become our most requested summer treat. Something magical happens when those humble graham crackers transform overnight!
Ingredients
- Instant cheesecake pudding: Adds a tangy richness that elevates this beyond a basic dessert. The cheesecake flavor perfectly complements the strawberries.
- Whole milk: Creates the creamiest texture. Avoid reduced fat versions as they won't set as firmly.
- Cool Whip: Lightens the pudding mixture and creates that cloudlike texture. Full fat version works best for proper structure.
- Graham crackers: Form the cake "layers" as they soften. Traditional honey grahams provide the best flavor but chocolate ones work beautifully too.
- Fresh strawberries: Bring brightness and natural sweetness. Look for berries that are fragrant and deep red throughout without white shoulders.
Step-by-Step Instructions
- Prepare the filling:
- Whisk together pudding mix and cold milk until smooth and beginning to thicken about 2 minutes. The mixture should coat the back of a spoon but still be pourable. Gently fold in Cool Whip using a rubber spatula with a light hand. Overmixing will deflate the air that gives this dessert its fluffy texture.
- Create the base layer:
- Arrange graham crackers in a single layer covering the entire bottom of a 9×13 inch pan. You may need to break some pieces to fit the edges. This foundation layer is crucial for structure so ensure there are no large gaps.
- Begin the layering process:
- Spread one third of the pudding mixture evenly over the graham crackers using an offset spatula. Aim for about half inch thickness. Scatter a generous layer of diced strawberries across the pudding ensuring good distribution.
- Build the middle layer:
- Place another complete layer of graham crackers over the strawberries pressing very gently. Add another third of the pudding mixture spreading all the way to the edges. This middle layer provides the structure for the cake so be thorough with coverage.
- Complete the assembly:
- Top with the final layer of graham crackers followed by remaining pudding mixture. Arrange the last of the strawberries in an attractive pattern on top. Some people prefer to save the prettiest berries for this visible layer.
- Allow to set:
- Cover with plastic wrap without touching the surface and refrigerate for at least 6 hours though overnight is preferable. The magic happens during this resting period as the crackers absorb moisture and transform into cake.

My grandmother used to make a version of this with homemade whipped cream instead of Cool Whip. While I've modernized her recipe for convenience, I still use her trick of macerating some of the strawberries with a tablespoon of sugar before adding them. This creates a natural syrup that seeps into the layers adding incredible flavor.
Make It Your Own
This icebox cake is incredibly versatile. Try using chocolate graham crackers with fresh raspberries for a different flavor profile. You can also substitute banana pudding mix with sliced bananas for a banana pudding inspired version that's absolutely delightful. The basic formula stays the same just swap ingredients to match your flavor preferences.
Troubleshooting Tips
If your cake seems too soft after chilling, it likely needs more time to set. The minimum 6 hours is really just that a minimum. For best results, make this dessert the day before serving. If you're in a hurry, placing it in the freezer for 30 minutes before serving can help firm it up without freezing it completely.

Storage Information
This icebox cake will keep beautifully in the refrigerator for up to 3 days. Store leftover portions in an airtight container to prevent the cake from absorbing other flavors from your refrigerator. The texture actually improves slightly on the second day as the graham crackers continue to soften to the perfect consistency. For longer storage, freeze individual portions wrapped tightly in plastic wrap then aluminum foil. Thaw in the refrigerator overnight before enjoying.
