Step-by-Step Instructions

Here’s how to make No-Bake Lemon Eclair Cake:

Prepare the Lemon Filling:

Whip the Heavy Cream: In a large mixing bowl, use an electric mixer to beat the heavy cream until it forms soft peaks. Set aside.
Mix the Pudding: In another bowl, whisk together the instant lemon pudding mix and cold milk until it begins to thicken (about 2 minutes).
Add Cream Cheese and Sugar: In a separate bowl, beat the softened cream cheese with powdered sugar and vanilla extract until smooth and creamy.
Combine: Gently fold the whipped cream into the pudding mixture, then add the lemon juice and lemon zest, stirring until fully incorporated. Set aside.

Assemble the Cake:

Layer the Graham Crackers: In a 9×13-inch baking dish, arrange a layer of graham crackers to cover the bottom of the dish.
Add the Lemon Filling: Spread half of the lemon filling mixture over the graham crackers, smoothing it into an even layer.
Repeat the Layers: Place another layer of graham crackers on top of the filling, followed by the remaining lemon filling. Smooth the top layer to cover evenly.

Prepare the Lemon Glaze:

Make the Glaze: In a small bowl, whisk together the fresh lemon juice and powdered sugar until smooth. Drizzle the glaze over the top of the cake, spreading it gently with a spatula.

Chill and Serve:

Chill the Cake: Cover the dish with plastic wrap and refrigerate for at least 3.5 hours or until the cake has set and the layers are firm.
Serve: Once chilled, slice into squares and serve. Garnish with extra lemon zest or a few fresh berries, if desired.

Additional Tips

Let it Chill: Be sure to let the cake chill long enough to set. It’s best to prepare it a few hours in advance so the flavors can meld and the cake firms up.
Use Fresh Lemon Juice: For the best flavor, use fresh lemon juice and zest rather than bottled juice. It adds a more vibrant and natural citrus flavor.
Layer the Crackers Quickly: When layering the graham crackers, try not to let them sit in the milk for too long to prevent them from becoming too soggy.
Add Extra Zest for More Flavor: If you love lemon, feel free to add more zest to both the filling and the glaze for a stronger lemon flavor.
Store Leftovers: Store any leftovers in an airtight container in the refrigerator for up to 3 days.
