This classic French éclair recipe offers the perfect balance of crisp pate a choux pastry, silky vanilla pastry cream, and rich chocolate ganache. After perfecting this technique over countless Sunday baking sessions, I've found these éclairs rival any Parisian patisserie's offerings while being completely achievable in a home kitchen.
The first time I made these éclairs was for my mother's birthday. She had reminisced about the ones she enjoyed during her travels in France decades ago. When she took her first bite, tears welled in her eyes as the flavors transported her back to that Parisian café. Now they're our special tradition.
Ingredients
- Bread flour: For the perfect structure in your choux dough that helps the éclairs hold their shape during baking
- Whole milk and heavy cream: Create the richness that makes these pastries truly special
- High quality vanilla extract: Infuses the pastry cream with aromatic sweetness
- Dark or bittersweet chocolate: Gives the ganache sophisticated depth rather than cloying sweetness
- Cornstarch: Stabilizes the custard filling and ensures it holds its shape when piped
- Unsalted butter: Allows you to control the salt level while adding necessary richness
Step-by-Step Instructions
- Prepare the pate a choux:
- Cook milk, water, butter, sugar, and salt until butter melts completely. The liquid temperature needs to be hot enough to partially cook the flour but not boiling. Add all flour at once and stir vigorously until a smooth ball forms. Continue cooking and stirring for a full minute to remove excess moisture and cook the raw flour taste out.
- Mix in eggs:
- Transfer dough to a mixer with paddle attachment. Add beaten eggs incrementally, allowing each addition to fully incorporate before adding more. Stop when the dough becomes glossy and forms a V-shape when lifted with a spatula. This careful addition prevents a runny dough that won't hold its shape.
- Pipe the éclairs:
- Fill pastry bag with prepared dough and pipe 4-inch cylinders onto parchment-lined baking sheets. Maintain even pressure throughout piping for consistent thickness. Use a wet fingertip to gently press down any pointed ends for a smooth finish.
- Bake with precision:
- Start at 400°F for 15 minutes to create the initial rise, then reduce to 350°F to dry out the centers without burning. Never open the oven during baking as temperature fluctuations can cause deflation. The finished éclairs should be golden brown and feel hollow when tapped.
- Create silky pastry cream:
- Whisk egg yolks, sugar, and cornstarch until pale. Heat milk and vanilla until steaming, then gradually temper into egg mixture while whisking constantly. Return to heat and cook until thickened, allowing it to bubble briefly. Strain immediately to remove any lumps and add butter for richness.
- Prepare the ganache:
- Pour hot cream over chopped chocolate and let stand before stirring to prevent graininess. The finished ganache should coat the back of a spoon but still be fluid enough to create a smooth top.
- Assemble the éclairs:
- Pierce two small holes in the bottom of each cooled éclair. Fill with pastry cream until you feel resistance. Dip tops in slightly cooled ganache for a glossy finish. Refrigerate briefly to set the ganache before serving.

My grandmother taught me to make choux pastry when I was just twelve. She insisted on using a wooden spoon rather than a mixer for the initial dough because she could feel when it reached the right consistency. To this day, I still reach for her worn wooden spoon when making éclairs, and somehow they always taste better when made with this small connection to my family's baking heritage.
Troubleshooting Your Éclairs
The most common issue with éclairs is deflation after baking. This usually occurs when the oven temperature fluctuates too drastically or when the shells are removed from heat before fully setting. Once baked, make a small slit in each éclair to release steam and prevent soggy interiors. If your shells still collapse, try adding the eggs more gradually next time and ensure your oven maintains a consistent temperature.
Flavor Variations
While classic vanilla pastry cream and chocolate ganache create the quintessential éclair, the possibilities for customization are endless. Consider filling with coffee pastry cream and topping with coffee glaze for a mocha version. For a seasonal twist, infuse the pastry cream with orange zest during winter months or fold in fresh berry puree during summer. You can even add a layer of salted caramel beneath the chocolate ganache for added indulgence.
Make-Ahead Tips
Éclair making becomes more manageable when broken into stages. The pastry cream can be prepared up to two days ahead and stored with plastic wrap directly touching the surface. Unfilled éclair shells stay crisp for about 24 hours when stored in an airtight container. For longer storage, freeze the baked but unfilled shells for up to a month. The ganache can be made several hours ahead and gently rewarmed to proper consistency before using.

These éclairs bring the magical charm of Paris right into your kitchen, a true labor of love that's worth every bite.
Frequently Asked Questions
- → Why does the eclair dough need to be cooked on the stovetop first?
Cooking the dough gelatinizes the flour and helps it hold moisture, which turns to steam in the oven, puffing the pastry for hollow centers.
- → Can I make the pastry cream ahead of time?
Yes, prepare it up to 2 days in advance and refrigerate with plastic wrap pressed on top. Fold in whipped cream before filling.
- → Why do you bake eclairs at two different temperatures?
Start hot to create steam for rise, then lower the temp to dry and set the pastry, ensuring they don't collapse or burn.
- → How do I know I’ve added enough egg to the dough?
The dough should be smooth, pipeable, and fall in a V-shape off a spoon. Add eggs gradually until this texture is reached.
- → Why shouldn't I open the oven while baking?
Opening the door early releases steam and heat, causing the eclairs to deflate before their structure is set.
- → What's the best way to fill eclairs without breaking them?
Use a piping bag to fill through small holes in the base of each eclair, preserving their shape and appearance.
