How to Make Coffee Éclairs (Éclairs au Café) at Home

The coffee éclair is the quieter twin of the chocolate one, and many pastry lovers think it is the better of the two: a crisp, hollow choux shell, a silky coffee pastry cream inside and a pale mocha glaze on top. It looks like a bakery-only project, but it breaks down into three simple components you can spread over a day. Here is how to make coffee éclairs at home: bake the choux, cook and chill a coffee crème pâtissière, then fill and glaze. Instant coffee is the secret: it flavors the cream and the glaze strongly without adding extra liquid.

A short history of the éclair

Éclairs come from 19th-century France. Before about 1850 these finger-shaped choux pastries were known as pain à la duchesse or petite duchesse; the pastry chef Jules Gouffé, writing in his 1873 Livre de Pâtisserie, noted that the name had changed about twenty years earlier. The word éclair, meaning a flash of lightning, is first recorded in French and English in the 1860s. A popular explanation is that the pastry is eaten in a flash.

You will often read that the great chef Antonin Carême invented the éclair. Some food historians have suggested it, but there is no firm evidence, so treat it as a plausible theory rather than fact. Coffee and chocolate fillings have been classic flavors for as long as éclairs have had their name.

How to make coffee éclairs: plan your bake

Makes about 12 éclairs, 5 inches (12 to 13 cm) long.

Step 1: Coffee pastry cream

Ingredients

• 2 cups (480 ml) whole milk
• 2 tablespoons instant coffee (or 1 1/2 tablespoons espresso powder)
• 5 large egg yolks
• 1/2 cup (100 g) granulated sugar
• 1/4 cup (30 g) cornstarch
• Pinch of salt
• 2 tablespoons (28 g) unsalted butter
• 1 teaspoon vanilla extract

Method

1. Heat the milk until steaming, then whisk in the instant coffee until dissolved.
2. In a bowl, whisk the yolks, sugar, cornstarch and salt until pale and smooth.
3. Slowly whisk half the hot milk into the yolks, then pour everything back into the pan.
4. Cook over medium heat, whisking constantly. When it thickens and starts to bubble, keep whisking for one full minute so the cornstarch cooks out.
5. Off the heat, whisk in the butter and vanilla. Pour into a shallow dish, press plastic wrap onto the surface and chill at least 2 hours.

For a stronger coffee hit, add an extra teaspoon of instant coffee dissolved in a few drops of hot water. If you like a lighter filling, fold in 1/2 cup (120 ml) whipped cream just before piping.

Step 2: Choux pastry shells

Ingredients

• 1/2 cup (120 ml) water
• 1/2 cup (120 ml) whole milk
• 1/2 cup (113 g) unsalted butter, cubed
• 1 teaspoon sugar and 1/2 teaspoon salt
• 1 cup (125 g) all-purpose flour, sifted
• 4 large eggs (about 200 g without shells), beaten, plus a little extra if needed

Method

1. Heat the oven to 400°F (200°C) and line two baking sheets with parchment. Draw 5-inch (12 to 13 cm) guide lines on the underside if you like.
2. Boil the liquids. Bring the water, milk, butter, sugar and salt to a full boil.
3. Add the flour all at once and stir hard with a wooden spoon. Keep stirring over medium heat for 2 to 3 minutes until the dough forms a ball and a thin film coats the pan. This dries the dough, which helps it puff.
4. Cool slightly. Transfer to a bowl or stand mixer and beat for a minute to release steam.
5. Add the eggs gradually, beating well after each addition. Stop when the dough is glossy and falls from the spoon in a thick V shape. You may not need all the egg.
6. Pipe. Using a bag with a 1/2-inch (12 to 14 mm) French star or round tip, pipe 5-inch logs about 1 inch (2.5 cm) wide, leaving space between them. A star tip helps prevent random cracks.
7. Bake 15 minutes at 400°F (200°C), then lower to 350°F (175°C) and bake another 20 to 25 minutes until deep golden and firm. Do not open the oven in the first 20 minutes.
8. Dry them. Poke a small hole in each end with a skewer and return to the switched-off oven, door ajar, for 10 minutes. Cool completely on a rack.

Step 3: Fill and glaze

Coffee glaze

• 1 1/2 cups (180 g) powdered sugar, sifted
• 1 tablespoon instant coffee dissolved in 2 tablespoons hot water
• 1 teaspoon light corn syrup or honey for shine (optional)
• 1 to 2 teaspoons extra water, as needed

Whisk until smooth and thick enough to coat the back of a spoon. It should flow slowly, like honey. Our coffee glaze recipe has more variations.

Fill

1. Whisk the chilled pastry cream until smooth and spoon it into a piping bag with a small round tip.
2. Poke two or three small holes in the bottom of each shell and fill through each hole until the éclair feels heavy. Wipe off any excess.

Glaze

1. Dip the top of each éclair in the glaze, lift, let the excess drip off and run a finger along the edge for a clean line.
2. Set on a rack for 20 minutes. Decorate with a chocolate-covered espresso bean or a thin drizzle of melted chocolate.
3. Refrigerate if not serving within an hour.

Which coffee to use

Instant coffee gives the most concentrated flavor in pastry cream and glaze, and our Instant Coffee dissolves cleanly with no grit. To serve alongside, a dark roast echoes the flavors: French Roast is bold and smoky-sweet with bittersweet chocolate notes, and Italian Roast is our darkest and most intense. For a deep dive on powders, see what espresso powder is.

Troubleshooting coffee éclairs

Variations

• Mocha éclairs: melt 2 oz (55 g) dark chocolate into the pastry cream after cooking.
• Coffee whipped cream filling: lighter and quicker; see our coffee whipped cream.
• Profiteroles: pipe the same dough into small rounds and fill the same way.

Coffee éclairs FAQ

Can I make éclairs a day ahead?

Yes, partly. Bake the shells and make the pastry cream a day ahead, keep them separate, then fill and glaze on the day. Re-crisp the shells for 5 minutes at 350°F (175°C) if needed.

Can I freeze éclair shells?

Yes. Freeze unfilled, cooled shells in an airtight container for up to a month, then re-crisp in a hot oven for a few minutes.

Can I use brewed espresso instead of instant coffee?

You can replace some of the milk with espresso in the pastry cream, but the flavor will be milder and the cream softer. Instant coffee gives a stronger result without thinning it.

What is the difference between an éclair and a cream puff?

The same choux dough, a different shape: éclairs are long and usually glazed, cream puffs are round and often dusted with sugar.
