What is an Icebox Cake?
The name comes from the old-fashioned icebox, which was the early version of today’s refrigerator. These no-bake desserts were chilled there until set, and that cold resting time is still what makes an icebox cake so special. As it rests, the graham crackers or cookies soften into tender layers with a cake-like texture.
Ingredients
A few easy ingredients are all it takes to make this easy icebox cake recipe.
- Instant Lemon Pudding: Be sure to use instant lemon pudding mix, not cook-and-serve, so the filling thickens quickly and sets properly.
- Cream Cheese: Fully softened cream cheese blends more smoothly into the filling and helps prevent lumps.
- Lemon Juice: Fresh lemon juice gives the brightest, freshest flavor.
- Blueberry Pie Filling: Pre-made pie filling adds sweet fruit flavor and a syrupy texture that helps create distinct layers throughout the cake.
- Whipped Topping: Whipped topping keeps the pudding layer light and fluffy while adding a smooth, creamy finish.
- Garnishes: Fresh blueberries and lemon slices are simple classic options, but lemon zest, extra whipped topping, or graham cracker crumbs are delicious too.
How to Make Lemon Blueberry Icebox Cake
I’ve made enough layered no-bake desserts to know that the little details matter, and this recipe is written to give you creamy layers, bright lemon flavor, and slices that hold together beautifully.
STEP ONE: Before layering, make sure the lemon filling is thick, smooth, and creamy, with no lumps of cream cheese. Softened cream cheese makes a big difference here and helps the filling blend up evenly.
STEP TWO: Add the blueberry pie filling in small spoonfuls, then spread it gently so the layers stay pretty and defined. A light hand keeps the lemon and blueberry layers from mixing together too much.
STEP THREE: Once chilled, the cake should be firm enough to slice neatly while still looking soft and creamy. The graham crackers will have softened into that signature cake-like texture that makes icebox cakes so good.
Tips for Success
These simple tips will help you get the best texture, neatest layers, and prettiest slices.
- Patch the corners with broken graham crackers: Break a few crackers into smaller pieces to fill any gaps so the layers stay even and each slice holds together better.
- Chill overnight for the best texture: The cake can be served after 4 to 6 hours, but overnight gives the graham crackers an even softer, more cake-like texture.
- Freeze briefly for cleaner slices: If you want especially tidy squares, pop the cake in the freezer for about 20 minutes before slicing.
FAQ
Lumpy filling usually means the cream cheese was still too cold when it was mixed in. Let it soften fully first so it blends smoothly into the pudding mixture.
Yes, 3 cups of fresh blueberries can work as a swap if you want a less-sweet, more natural, fruit-forward flavor. The biggest difference is texture, since blueberry pie filling creates a softer, more cohesive layer, while fresh berries make the fruit layer a little lighter and the slices slightly less defined.
Stabilized whipped cream works best in place of Cool Whip because it stays fluffy and holds its shape better after chilling than regular homemade whipped cream. Our Homemade Cool Whip is a great substitute since it has the same creamy texture and can be stored in the fridge for up to 3 days.
Storage and Make-Ahead
This icebox cake is a great make-ahead dessert since it needs time to chill before serving. You can keep it covered in the refrigerator for 2 to 3 days, and the texture is usually best after several hours or overnight.
If you want to freeze it, wrap it tightly in plastic wrap, then foil, and freeze for up to 1 month. When you’re ready to serve, let it thaw in the refrigerator overnight so the layers soften enough to slice cleanly.

Ingredients
- 6.8 ounces instant lemon pudding mix (2 small boxes)
- 2 ½ cups milk
- ½ cup lemon juice
- 8 ounces cream cheese at room temperature
- 6 cups Cool Whip thawed (two 8-ounce tubs)
- 27 graham crackers (3 sleeves)
- 2 cans blueberry pie filling (21 ounces each)
- 1 cup fresh blueberries for garnish
- 1 lemon halved and cut into slices, for garnish
Instructions
- In a large mixing bowl, beat together 6.8 ounces instant lemon pudding mix with 2 1/2 cups milk and 1/2 cup lemon juice for 2 minutes, until thickened. Add 8 ounces cream cheese and beat again until smooth. Use a rubber spatula to fold in 2 cups Cool Whip until completely combined.
- Line a 9-inch x 13-inch baking dish with 9 Graham Crackers. If you need to fill in a few spots, break the crackers into small pieces to fit in the gaps.
- Spread half of the lemon pudding mixture over the graham crackers. Then add 1 cans blueberry pie filling in dollops over the pudding and gently spread it out.
- Top the blueberries with another layer of 9 Graham Crackers. Fitting to the pan just like the first layer. Then top with the remaining pudding mixture and 1 cans blueberry pie filling. Layer the remaining 9 Graham Crackers over the filling. Spread 4 cups Cool Whip over the graham crackers.
- Cover the dish with plastic wrap and refrigerate for 4-6 hours to let the pudding set up and the graham crackers soften to a cake-like texture.
- Right before serving, top the icebox cake with half lemon slices and fresh blueberries for garnish. Cut into 12 slices and enjoy!
Notes
- If you don’t have Cool Whip available at your local grocery store, you can use Homemade Cool Whip instead.
- Chill overnight for the softest texture and easiest slicing.
- Freeze for 20–30 minutes before serving for cleaner slices.
- Store covered in the refrigerator for 2–3 days or freeze for longer storage.

DELICIOUS!!!!!
Janice Taylor says
I think crushed Graham crackers would work better between layers.
Jessica says
How in the world do you get the cream cheese to combine smoothly with the pudding mixture? I’ve blended, hand whisked, and used a silicone spatula trying to smooth it all out but I still have lumps or flakes of cream cheese.
Jennifer Kimmel says
Hey Jessica! Have you tried letting the cream cheese soften to room temperature? That might help.
Rebecca Cox says
I cannot find the recipe !!!!

Hello Rebecca, the link has been fixed. Sorry about that.

OMG! A new FAVORITE! I’d add a picture if it let me!
Andrea says
This looks really good, but please check and check and correct the ingredients. Where does the cream cheese go? If I only put 2 cups of cool whip with the pudding, there will be about 4 cups left for the top. Is that correct?
Julie Kotzbach says
Hi Andrea! Thank you for letting us know about the ingredient omission! We’ve updated the recipe to reflect that the cream cheese should be mixed in with the pudding before folding in the Cool Whip. Yes, you should have 4 cups of Cool Whip left to over the top of the icebox cake.

The ingredients list doesn’t mention cream cheese but instructions say pudding cream cheese mixture. Lemon blueberry icebox cake looks wonderful and want to make.
