Introduction
Picture glossy eclairs crowned in blush-pink glaze, their crisp, golden shells giving way to clouds of lemon-kissed mousse speckled with ruby raspberries. Imagine the scent—butter warm from the oven, bright citrus zest perfuming the kitchen—promising that first, delicate crackle and a cool, velvety filling beneath. These are the kinds of desserts that comfort and cheer: pretty enough for celebrations, soothing enough for quiet evenings.
They matter to me because they turn simple ingredients into small moments of wonder—bite-sized pauses that make a long day feel softer. On busy weeknights, they’re a make-ahead treat to end dinner with grace; for Sunday suppers, they steal the show without stealing your time.
Once, a last-minute dinner invite had me scrambling; a tray of these eclairs—shells pre-baked, filling whisked—saved the night and earned every happy sigh at the table. Ready? Let’s cook!

Step-by-Step Method
Make the Choux Base
Preheat to 200°C. Line two sheets with parchment.
Boil water, milk, butter, sugar, and salt in a saucepan.
Add flour all at once. Stir vigorously until a smooth dough forms and a thin film coats the pan, about 2 minutes. Transfer to a bowl. Beat 2 minutes to cool slightly before adding eggs.
Beat In the Eggs
Add eggs one at a time, beating thoroughly after each.
Look for a glossy dough that falls in a thick, V-shaped ribbon from the spoon. If needed, add the last egg gradually to reach a pipeable consistency. Avoid overmixing. Load the dough into a piping bag fitted with a large round tip.
Pipe, Mist, and Bake
Pipe 12 logs about 12 cm long onto lined sheets.
Smooth tips with a damp finger. Lightly mist with water to encourage rise.
Bake 10 minutes at 200°C. Reduce to 180°C and bake 20–25 minutes until deeply golden and puffed. Don’t open the oven early to prevent collapse.
Vent, Dry, and Cool
Turn off the oven. Pierce each éclair with a skewer to release steam.
Leave in the turned-off oven with the door ajar for 10 minutes to dry interiors. Transfer to a rack and cool completely. Make sure shells are crisp and hollow before filling. This step prevents sogginess and maintains structure.
Cook the Lemon Pastry Cream
Whisk sugar and cornstarch with egg yolks until pale and smooth.
Heat milk with lemon zest to steaming. Temper by slowly whisking hot milk into yolks. Return to saucepan. Cook over medium heat, whisking constantly, until thick bubbles form. Remove from heat. Whisk in lemon juice and softened butter.
Strain, Set, and Chill
Strain pastry cream through a fine-mesh strainer for silkiness. Press plastic wrap directly onto the surface to prevent skin.
Chill for 1 hour until cold and set. For extra insurance, bloom gelatin in cold water, melt gently, and whisk into warm cream before chilling. Keep refrigerated until assembling.
Whip the Cream
Using cold equipment, whip heavy cream with powdered sugar and vanilla to medium peaks.
Avoid overbeating. The cream should hold ridges yet remain soft for folding. Keep chilled. Reserve half for folding into the pastry cream. Save the remaining half for another use or for extra garnish if desired.
Lighten and Fold In Berries
Fold half the whipped cream into the chilled lemon pastry cream to create a light mousse.
Use gentle, sweeping strokes to preserve volume. Gently fold in 100 g raspberries, halved if large. Avoid crushing the fruit. Chill briefly if the mixture softens. Prepare a piping bag for neat filling.
Split and Fill the Shells
Use a serrated knife to split éclairs horizontally.
Pipe or spoon the lemon-raspberry filling into the bases, distributing berries evenly. Avoid overfilling to prevent oozing. Set the tops aside for glazing. Work quickly to keep shells crisp. Chill filled bases while preparing the glaze.
Make the Raspberry-White Chocolate Glaze
Melt white chocolate with warm cream until smooth and glossy.
Stir in seedless raspberry jam for color and tang. Adjust thickness by gently warming or adding a teaspoon of cream. Aim for a pourable, not runny, consistency. Keep the glaze slightly warm for easy dipping or spreading.
Glaze the Tops
Dip éclair tops into the glaze or spread with an offset spatula for a smooth finish.
Let excess drip off. Place glazed tops on a rack to set slightly. Avoid stacking. If the glaze thickens, warm it briefly to restore flow. Keep the surface even for a professional look.
Assemble and Garnish
Place glazed tops onto filled bases.
Press gently to secure without squeezing out filling. Top with remaining raspberries, dried well to prevent bleeding. Arrange decoratively. Optionally add lemon zest for brightness. Chill 20–30 minutes to set the glaze and firm the filling before serving.
Serve and Store
Serve éclairs the day they’re filled for peak texture.
Keep chilled until serving, then let stand 5–10 minutes for best flavor. Store leftovers refrigerated in a covered container up to 24 hours. For make-ahead, freeze unfilled shells airtight and re-crisp at 160°C for 5–8 minutes before filling.
Ingredient Swaps
- Dairy-free: Use plant milk (oat or almond) in choux and pastry cream; swap butter for vegan block butter; whip coconut cream with sugar instead of heavy cream; use dairy-free white chocolate for glaze.
- Gluten-free: Replace all-purpose flour in choux with a 1:1 gluten-free baking blend (with xanthan gum); pastry cream uses cornstarch already.
- Egg-free: Choux and pastry cream rely on eggs—consider store-bought vegan éclair shells or make pâte à choux with aquafaba-based recipes; thicken “pastry cream” with extra cornstarch and a touch of vegan gelatin/agar.
- Budget/availability: Use frozen raspberries (thawed and well-drained) in filling; swap white chocolate glaze for a simple raspberry icing (powdered sugar + lemon juice + raspberry jam).
- Flavor swaps: Lime or orange zest/juice for lemon; strawberries, blueberries, or blackberries for raspberries; vanilla or almond extract in whipped cream.
You Must Know
Doneness • If piped logs start spreading or look slick, stiffen the pâte à choux with 5–10 g more flour beaten in while still warm; prevents flat shells by restoring body—look for peaks that hold for 2–3 seconds before slowly bending.
Troubleshoot • When shells look golden but feel soft at the sides, extend drying with door ajar until shells sound hollow and feel papery, 8–12 extra minutes; avoids collapse by driving off interior moisture to <15% (audible hollow “tap”).
Flavor Boost • For brighter lemon, swap half the vanilla in the cream chantilly for 1/4 tsp lemon extract or 1 tsp limoncello; balances the white chocolate sweetness—taste for a clean citrus finish without bitterness.
Scale • For 18 éclairs, multiply all components by 1.5 (e.g., 150% flour = 225 g, eggs ≈ 6); pipe to 12 cm still, just more pieces—baking time unchanged, but rotate sheets at the 10-minute mark for even color.
Make-Ahead • To keep shells crisp after filling for up to 6 hours, brush interiors lightly with melted white chocolate (about 5–7 g per shell) and set 10 minutes; creates a moisture barrier so bottoms stay snappy.
Serving Tips
- Dust tops with powdered sugar and lemon zest; add a few fresh raspberries.
- Plate with raspberry coulis swirls and a dollop of lightly sweetened whipped cream.
- Serve alongside lemon sorbet or vanilla gelato for a reviving contrast.
- Garnish with micro mint or basil and thin lemon peel curls.
- Pair with chilled prosecco, Earl Grey tea, or a citrusy mocktail.
Storage & Make-Ahead
Éclairs are best the day they’re filled.
Refrigerate assembled éclairs, covered, up to 24 hours.
Store empty shells airtight at room temperature 1 day, or freeze up to 1 month; re-crisp at 160°C for 5–8 minutes.
Chill pastry cream up to 2 days.
Whipped cream: whip fresh for best texture.
Reheating
Reheat gently: microwave 10–15 seconds at 50% power.
Or oven at 160°C for 5–8 minutes to re-crisp shells.
Or stovetop steam 1–2 minutes, covered.
Fill after reheating to avoid sogginess.
Parisian Patisserie Showcase
Through the glass of a Parisian patisserie, I spot rows of burnished choux—sleek éclairs crowned in blush raspberry glaze, jeweled with fresh berries—inviting a pause and a sigh.
I study the details you’ll want to emulate: shells baked to a deep, even gold; crisp sides with no sag; a clean slit revealing airy honeycomb. The filling sits proud, not oozing—light lemon mousse flecked with berries, piped in confident ribbons.
Notice the finish: a thin, glossy veil of raspberry-kissed white chocolate, smoothed with an offset spatula, then garnished with perfectly dry berries. I bring that showcase home by chilling glazed tops briefly, aligning each éclair neatly, and serving on a cool slate. Let your tray look curated—balanced spacing, tidy edges, unmistakably Paris.

Frequently Asked Questions
Can I Make These Gluten-Free Without Sacrificing Structure?
Yes. I’d swap flour for a strong 1:1 gluten-free blend with xanthan, add 1 extra egg white, and dry shells longer. Pipe thick ribbons, bake deeply golden, vent well—crisp exteriors, airy interiors, no collapse.
How Do Altitude Changes Affect Choux Pastry Rise?
High altitude makes choux expand faster, dry sooner, and collapse easier. I adjust by lowering oven temp slightly, increasing liquid, reducing eggs, and baking longer. I watch color, vent promptly, and cool thoroughly for sturdy, hollow shells.
What’s the Best Way to Transport Filled Éclairs?
Chill them firm, nestle in a snug, shallow box, parchment between layers, and keep tops upright. I pack ice packs beneath, drive gently, and finish garnishing on arrival. You’ll serve crisp shells and silky centers.
Can I Use a Dairy-Free Lemon Pastry Cream Alternative?
Yes—you can. I swap milk for coconut milk, butter for vegan butter, and whisk in cornstarch with yolks or use plant-based custard powder. I chill until thick, then fold dairy-free whipped cream. Bright, silky, irresistible.
How Do I Prevent Soggy Bottoms in Humid Climates?
Vent and dry shells in the oven, bake until deeply golden, then cool completely. I re-crisp at 160°C before filling, pipe only when ready, keep fillings thick, and chill briefly—humidity can’t sneak past a well-dried shell.
