Step‑by‑Step Instructions for No-Bake Lemon Éclair Cake

Step 1: Prepare the Dish
Start by spraying a 9×13-inch baking dish with nonstick cooking spray to ensure your No-Bake Lemon Éclair Cake releases easily later. This step is crucial for smooth serving. Set the dish aside, allowing you to focus on creating the delicious layers without any sticking worries.

Step 2: Lay the Base
Begin layering the bottom of the prepared dish with graham crackers. Break them as needed to fit snugly, creating a solid foundation. This first layer is essential as it will soften and blend beautifully with the pudding layers, adding that signature texture to your No-Bake Lemon Éclair Cake.

Step 3: Mix the Pudding
In a large mixing bowl, whisk together the two boxes of instant lemon pudding along with 3½ cups of cold milk. Stir for about 2 minutes until the mixture is smooth and slightly thickened—this is critical for achieving that creamy consistency. It should form a lovely, luscious pudding that will be the highlight of your dessert.

Step 4: Incorporate the Cool Whip
Next, gently fold in the thawed Cool Whip into the lemon pudding mixture until just combined. Use a spatula and take care not to deflate the whipped cream too much, maintaining that airy texture. This fluffy blend will elevate the flavor and lighten the overall cake, making each layer irresistibly creamy.

Step 5: Build the Layers
Spread half of the creamy pudding mixture evenly over the first layer of graham crackers in the dish. Use a spatula for smoothness. Pay attention to covering every corner, creating a rich layer that will balance perfectly with the next layer of graham crackers, setting the stage for more flavor within your No-Bake Lemon Éclair Cake.

Step 6: Repeat with More Crackers
Place another layer of graham crackers over the pudding mixture. Gently press them down to ensure they are nestled into the pudding, allowing the flavors to meld together. This step is vital in creating that signature layered effect that makes this dessert visually appealing and delicious.

Step 7: Add the Remaining Pudding
Now, pour the remaining pudding mixture over the second layer of graham crackers and spread it evenly with your spatula. This layer should be rich and generous, enhancing the overall flavor profile of your No-Bake Lemon Éclair Cake. Keep the pudding smooth and even for a beautiful final presentation.

Step 8: Top with Graham Crackers
Finish off with one last layer of graham crackers on top of the pudding. Make sure this layer is also even, mimicking the other layers, ensuring structural integrity as your cake sets. This final touch helps create a delightful contrast of textures in every bite.

Step 9: Frost the Cake
To add the zesty topping, microwave the lemon frosting for about 30 seconds until it softens—don’t overheat it. Carefully spread the frosting over the top layer of graham crackers, allowing it to ooze slightly into the cracks. This tangy frosting will provide a sweet finish that complements the creamy layers underneath.

Step 10: Chill and Set
Cover your No-Bake Lemon Éclair Cake with plastic wrap and refrigerate for at least 12 hours, preferably overnight. This chilling time allows the graham crackers to soften and the flavors to meld beautifully, resulting in a delightful dessert ready to impress your guests when served.

Step 11: Serve and Slice
Once chilled, remove the cake from the refrigerator. Use a sharp knife to slice the cake into squares, revealing the delicious layers inside. Each slice will hold the creamy pudding, soft graham crackers, and tangy frosting, making it an irresistible treat for any occasion.
