How to Make Perfect Éclairs

Step 1: Prepare Your Oven and Trays. Preheat your oven to 180°C/350°F (160°C fan). Position one shelf in the top third of the oven and another in the lower third. Lightly spray three baking trays with canola oil and line them with baking/parchment paper. This ensures your choux pastry won’t stick and bake evenly.

Step 1

Step 2: Start the Choux Pastry Base. In a medium saucepan, melt the unsalted butter over medium heat. Once the butter is almost fully melted, add the water. Bring this mixture to a gentle simmer.

Step 3: Create the Dough Ball. As soon as the liquid begins to simmer, add the flour and a pinch of salt. Vigorously stir with a sturdy wooden spoon while still on the stove. The mixture will quickly turn into a paste and then form a sticky ball of dough that pulls away cleanly from the sides of the saucepan within about 10 seconds. Remove the saucepan from the heat and let the dough cool for precisely 10 minutes – no longer, as this is crucial for the texture.

Step 4: Incorporate the Eggs. After the dough has cooled, add the eggs one at a time. After each egg addition, mix vigorously with a wooden spoon or an electric beater until each egg is fully incorporated into the dough. Initially, the mixture may appear separated, but continue stirring until it comes together smoothly. The final mixture should be a sticky, thick paste that holds its shape well, not loose or sloppy.

Step 5: Pipe the Éclair Shapes. Transfer the choux pastry mixture into a piping bag fitted with a 15 mm star tip. Carefully pipe logs that are 12-14 cm (5 inches) long, 2.5 cm (1 inch) wide, and 1.5 cm (0.6 inches) tall, ensuring they are spaced about 5 cm (2 inches) apart on the prepared baking trays. Do not overcrowd the trays, as this can prevent the éclairs from becoming crispy. You should yield approximately 20 éclairs.

Step 6: Bake the Choux Buns. Place two trays of piped choux pastry into the preheated oven and bake for 45 minutes. To achieve optimal crispiness, open the oven door for 2 seconds at the 30-minute mark to release steam, then repeat this process at 35 minutes and 40 minutes. After 45 minutes, remove the trays from the oven. If you have a third tray of choux pastry, bake it following the same directions.

Step 7: Cool and Prepare for Filling. Once removed from the oven, allow the choux buns to cool completely on the baking trays. This step is essential for maintaining their crisp texture. Once cooled, use a serrated knife to carefully slice each choux bun horizontally in half, creating a top and bottom for your éclairs.

Step 8: Make the Chocolate Glaze. Place the finely chopped 70% cocoa dark chocolate in a heatproof bowl. In a small saucepan, heat the thickened/heavy cream and corn syrup (or liquid glucose) over medium heat until it is just below boiling. Pour this hot cream mixture over the chocolate, gently shaking the bowl to ensure the chocolate is submerged. Let it stand for 1 minute to allow the chocolate to melt.

Step 9: Finish the Glaze. Using a rubber spatula, gently mix the chocolate and cream until the mixture is completely smooth and glossy. Avoid using a whisk, as this can introduce air bubbles and make the glaze less smooth. Transfer the finished glaze into a wide, shallow bowl large enough to easily dip the éclair tops.

Step 10: Glaze the Éclairs. Dip the top half of each sliced éclair into the chocolate glaze, ensuring it’s evenly coated. Place the glazed tops on a clean tray and refrigerate for about 30 minutes, or until the chocolate glaze is firm to the touch. This sets the glaze beautifully.

Step 11: Prepare the Chantilly Cream. In a clean bowl, combine all the Chantilly Cream ingredients: 3 cups thickened/heavy cream, 1 cup mascarpone, 1 2/3 cups sifted icing sugar/powdered sugar, and 2 tsp vanilla bean paste or extract. Using an electric beater on medium-high speed, whip the mixture for approximately 3 minutes, or until stiff peaks form. The cream should be light, airy, and hold its shape.

Step 12: Assemble and Serve. Transfer the whipped Chantilly cream into a piping bag fitted with a star tip. Generously pipe the cream onto the bottom half of each éclair, using any decorative pattern you prefer. Place the chocolate-glazed lid on top of the cream, gently pressing down. Serve your freshly assembled éclairs immediately and enjoy!

Instructions

  1. Preheat oven to 180°C/350°F (160°C fan). Position one shelf in the top third of the oven and another in the lower third. Lightly spray 3 trays with canola oil and line with baking/parchment paper.
  2. Melt butter in a medium saucepan over medium heat. When the butter is almost melted, add water.
  3. Once the liquid starts simmering, add flour and salt, and vigorously stir with a wooden spoon (while still on the stove). The mixture will turn pasty then in about 10 seconds it will transform into a sticky ball of dough that comes away from the walls of the saucepan. Once this happens, remove from the stove and leave to cool for 10 minutes (no longer).
  4. Add eggs one at a time, mixing vigorously with a wooden spoon after each addition, making sure each egg is incorporated before adding the next. At first, the mixture will look separated but when you keep stirring, it comes together. When finished the mixture should be a sticky, thick paste that holds its shape, not sloppy and loose.
  5. Transfer mixture into a piping bag fitted with a 15 mm star tip. Pipe logs 12-14 cm long, 2.5 cm wide, 1.5 cm tall, 5 cm apart from each other. (5″ long, 1″ wide, 0.6″ tall, 2″ apart) Do not crowd the tray else they won’t go crispy. You should get around 20.
  6. Bake 2 trays on the shelves for 45 minutes. At the 30 minute mark, open the oven door for 2 seconds to release steam (makes them crispier), then again at 35 minutes and 40 minutes. Remove the tray at 45 minutes.
  7. Remove choux buns from the oven and allow to fully cool on the trays. If you used 3 trays, bake the 3rd tray of choux pastry per above directions.
  8. Slice choux buns in half horizontally.
  9. Place chocolate in a bowl.
  10. Heat cream and glucose in a small saucepan over medium heat until just below boiling. Pour mixture over chocolate, shake so the chocolate is submerged. Let stand for 1 minute.
  11. Mix with a rubber spatula until smooth (do not use a whisk, it creates bubbles). Transfer into a wide, shallow bowl large enough to dip the eclairs.
  12. Dip the lid of each éclair into the chocolate. Place on a tray and refrigerate for 30 minutes until the chocolate is firm to the touch.
  13. Place all the Chantilly Cream ingredients in a bowl. Whip using an electric beater on medium high for 3 minutes or until stiff peaks form. Transfer into piping bag fitted with a star tip.
  14. Pipe in cream using whatever pattern takes your fancy, generously thick. Place the lid on then serve!

Frequently Asked Questions

What is choux pastry?

Choux pastry, also known as pâte à choux, is a light pastry dough used in many French desserts like éclairs and cream puffs. It’s unique because it’s cooked twice – first on the stovetop to form a dough ball, then baked in the oven where steam causes it to puff up and become hollow inside.

Why did my éclairs not puff up?

Common reasons for éclairs not puffing include: the dough being too hot when eggs are added (cooking the eggs), adding too many eggs (making the dough too wet), not cooking the dough long enough on the stovetop, or opening the oven door too early or too often during baking, which causes the steam to escape.

Can I make éclairs ahead of time?

You can prepare the choux pastry shells a day in advance and store them in an airtight container at room temperature. The chocolate glaze can also be made ahead and gently reheated. However, it’s best to whip the Chantilly cream and assemble the éclairs just before serving to prevent the pastry from becoming soggy.

What kind of cream should I use for Chantilly cream?

For Chantilly cream, you should use thickened or heavy cream with a minimum fat content of 35%. This ensures the cream whips up to stiff peaks and holds its shape well. Combining it with mascarpone, as in this recipe, adds extra richness and stability.

Conclusion

And there you have it – your very own batch of exquisite homemade éclairs! This journey from simple ingredients to a stunning dessert is incredibly rewarding, proving that even the most elegant pastries are within reach for the home baker. The crisp choux pastry, the rich chocolate, and the light Chantilly cream create a symphony of textures and flavors that are truly irresistible.

Don’t be afraid to experiment with different fillings or glazes once you’ve mastered this classic version. Perhaps a coffee-flavored cream or a white chocolate drizzle for a twist? The possibilities are endless. We hope this guide inspires you to embrace your inner pastry chef and delight in the process of creating these beautiful treats.
