No-Bake Lemon Eclair Cake: A Slice of Sunshine on a Spoon

There’s something about lemon desserts that feels like a hug from the sun—bright, cheerful, and utterly irresistible. I remember the first time I tasted a lemon eclair at a little patisserie in Paris. The delicate pastry, the tangy cream, the glossy glaze… pure magic. But let’s be honest, whipping up choux pastry at home isn’t always practical (or possible on a lazy afternoon). That’s why this No-Bake Lemon Eclair Cake is my go-to when I crave that same citrusy bliss without the fuss. Layers of graham crackers, velvety lemon cream, and a dreamy glaze come together in a dessert that’s as easy as it is elegant—perfect for potlucks, picnics, or just because you deserve a little sunshine today.

Ingredients You’ll Need

Graham crackers – The foundation of our no-bake “pastry” layers. Their honey-kissed sweetness pairs beautifully with the tart lemon.
Cream cheese (8 oz, softened) – For that luscious, tangy base. Pro tip: Let it sit at room temperature for 30 minutes—it’ll blend smoother than a summer breeze.
Heavy cream (1 cup) – Whipped to soft peaks, this gives the filling its cloud-like texture.
Powdered sugar (1 cup) – Just enough sweetness to balance the lemon’s zing.
Lemon zest + juice (2 lemons) – Fresh is non-negotiable here! The zest adds that fragrant pop, while the juice brings the vibrant tang.
Vanilla extract (1 tsp) – A whisper of warmth to round out the flavors.
Instant lemon pudding mix (3.4 oz box) – Our secret weapon for extra lemony depth (and effortless thickening).
Milk (1 ½ cups) – Whole milk makes the creamiest filling, but 2% works in a pinch.
White chocolate chips (1 cup) – For the glossy glaze that mimics classic eclair topping.

Let’s Make Some Magic

First, let’s create that dreamy lemon filling. In a large bowl, beat the softened cream cheese until it’s as smooth as satin—about 2 minutes. Add the powdered sugar, lemon zest, juice, and vanilla, then whip until everything is happily combined. In another bowl, whisk the pudding mix with milk until thickened (it’ll happen fast!), then gently fold it into the cream cheese mixture. Now, take that heavy cream and whip it to soft peaks—think pillowy, not stiff—before folding it into the lemon bliss. This step keeps the filling light as a summer cloud.

Next, assemble your “eclair” layers. In an 8×8 dish, arrange a single layer of graham crackers, breaking them as needed to fit. Spread half the lemon filling over the crackers like you’re tucking them into a citrusy blanket. Repeat with another layer of crackers and the remaining filling. Top with a final layer of graham crackers—this will be your canvas for the glaze. Cover and let the cake chill in the fridge for at least 4 hours (overnight is even better!). The waiting is the hardest part, but trust me, it’s worth it.

Frequently Asked Questions

Can I make this ahead of time?
Absolutely! In fact, it tastes even better after the flavors meld overnight. Just add the final whipped topping layer right before serving.

My pudding seems runny – what went wrong?
This usually means the pudding needed more time to set. Pop the whole cake in the fridge for an extra hour, or use instant pudding mix for quicker results.

Can I use fresh lemons instead of lemon curd?
Yes! Combine 1/2 cup lemon juice with 3 tbsp sugar and 2 tsp cornstarch, simmer until thickened, then cool completely before using.

Is there a way to make this lower sugar?
Try sugar-free pudding mix and reduced-fat whipped topping. The graham crackers will still provide some sweetness.
