I can still remember the first time I brought this dessert to a summer potluck. The moment I set the pan on the table, it was surrounded. This No Bake Lemon Eclair Cake is pure sunshine in a 9×13 pan, layering bright lemon pudding, creamy cheesecake filling, and tender graham crackers, all topped with a sweet lemon frosting. It’s the kind of effortless, crowd-pleasing dessert that tastes like you spent hours in the kitchen, but it’s our little secret that the oven never even had to turn on. It’s an “icebox cake,” a classic American treat where layers soften and meld together in the fridge to create a wonderfully cake-like texture.

Ingredients
- 3.4 ounces instant lemon pudding mix
- 1 1/2 cups milk
- 4 ounces whipped topping (thawed, like Cool Whip)
- 3.4 ounces instant cheesecake pudding mix
- 1 1/2 cups milk
- 4 ounces whipped topping (thawed, like Cool Whip)
- 20 sheets graham cracker sheets (about 2 ½ sleeves)
- 16 ounces lemon frosting
How to make No Bake Lemon Eclair Cake
Step 1: First, let’s make the lemon pudding filling. In a large bowl, whisk together the instant lemon pudding mix and 1 1/2 cups of cold milk until it’s smooth and starts to thicken. Gently fold in 4 ounces of the thawed whipped topping with a spatula until it’s just combined. You want to keep the mixture light and airy.
Step 2: Now for the cheesecake layer. In a second large bowl, repeat the process with the instant cheesecake pudding mix and the remaining 1 1/2 cups of cold milk. Whisk until smooth, then fold in the other 4 ounces of whipped topping.
Step 3: It’s time to assemble your cake! Arrange a single layer of graham cracker sheets to completely cover the bottom of a 9×13 inch baking pan. You may need to break some crackers to fit any gaps. Pour the entire lemon pudding mixture over the graham crackers and spread it into an even layer with your spatula.
Step 4: Place another full layer of graham crackers on top of the lemon pudding. Next, pour the cheesecake pudding mixture over this layer and spread it evenly from edge to edge.
Step 5: Add one final layer of graham crackers on top of the cheesecake pudding. Cover the pan and place it in the refrigerator to chill for about 30 minutes. This helps the layers set up before frosting.
Step 6: Once chilled, prepare the frosting. Remove the lid and foil from the lemon frosting container and microwave it for 15-20 seconds. Stir it well. You’re looking for a soft, easily spreadable consistency, not hot or melted. Pour the softened frosting over the top layer of graham crackers and spread it evenly to cover the entire cake.
Step 7: Cover the cake and return it to the refrigerator. For the best results, let it chill for at least 5 hours, or preferably overnight. This long chill time is crucial for the graham crackers to soften and absorb the moisture from the pudding, creating that signature “eclair” texture. Once chilled, slice, serve, and enjoy!
How to serve No Bake Lemon Eclair Cake

This lemon eclair cake is best served chilled, straight from the refrigerator. The cold temperature keeps the layers firm and makes the flavors extra refreshing. Cut it into squares and serve as is, or dress it up with a dollop of extra whipped topping and a sprinkle of lemon zest for a pop of color and flavor. It’s the perfect dessert to bring to a BBQ, a spring celebration like Easter, or just to have in the fridge for an easy weeknight treat.
How to store No Bake Lemon Eclair Cake
Storing this cake is simple. Keep it tightly covered with plastic wrap or a lid in the refrigerator. It will stay fresh and delicious for up to 4 days. In fact, many people find the texture is even better on the second day! I do not recommend freezing this cake, as the pudding layers can become watery upon thawing, which can change the texture.
Tips to make
- Use Cold Milk: Make sure your milk is very cold when you whisk it with the instant pudding mixes. This helps the pudding set up properly and become thick and creamy.
- Don’t Overmix the Topping: When folding in the whipped topping, use a gentle hand. You want to incorporate it without deflating all the air, which keeps the pudding layers light and fluffy.
- Break Crackers to Fit: Don’t worry about having perfect, whole graham cracker sheets for every layer. Break them as needed to fill in the gaps and create a solid base for each pudding layer. No one will see them!
- The Chill Time is Key: Be patient! The minimum 5-hour chill time (or overnight) is non-negotiable. This is when the magic happens, and the firm graham crackers transform into soft, cake-like layers.
- Use an Offset Spatula: An offset spatula makes spreading the pudding layers and the final frosting layer much easier and helps you get a smooth, professional-looking finish.
FAQs About No Bake Lemon Eclair Cake
Can I use a different flavor of pudding?
Absolutely! While the lemon and cheesecake combination is fantastic, you can easily customize this recipe. Try using two boxes of vanilla pudding for a classic eclair cake flavor, or get creative with combinations like strawberry and vanilla or even pistachio.
Do I have to use Cool Whip? Can I use real whipped cream?
You can use homemade stabilized whipped cream, but Cool Whip or other frozen whipped toppings are recommended because they are more stable. They hold their shape better and won’t weep or become watery over several days in the fridge, ensuring your cake stays perfect.
Why did my cake turn out runny?
The most common reason for a runny cake is not letting the pudding set properly. Ensure you are using “instant” pudding, not the “cook and serve” kind. Also, using very cold milk and whisking until the pudding is noticeably thick before folding in the whipped topping is crucial for the right consistency.
