A coffee eclair is an oblong pastry made with pâte à choux (choux pastry), filled with coffee crème pâtissière (coffee pastry cream), and topped with a coffee-flavored glaze or ganache. The word éclair means “flash of lightning” in French, likely referring to how quickly these pastries are eaten.
Coffee has long been paired with desserts in French pâtisseries. By infusing the classic éclair with espresso, chefs created a dessert that perfectly balances sweetness and bitterness. Today, coffee eclairs are a staple in Parisian bakeries, fine dining restaurants, and modern cafés worldwide.

Coffee Eclair Ingredients: What You Need
Making coffee eclairs requires three key components:
1. Choux Pastry for Coffee Eclair Shells
- Butter
- Water (or a water-milk mix for richness)
- All-purpose flour
- Eggs (provide structure and puff)
- A pinch of salt
This base forms the hollow shells that will be filled later.
2. Coffee Pastry Cream (Espresso Crème Pâtissière)
- Whole milk
- Egg yolks
- Granulated sugar
- Cornstarch or flour (for thickening)
- Instant espresso powder or freshly brewed espresso
- Vanilla extract (optional, to balance flavors)
This silky custard is the heart of the coffee eclair.
3. Coffee Ganache or Fondant Glaze
- Heavy cream
- Dark chocolate or white chocolate (for base)
- Instant espresso powder or strong coffee
- Powdered sugar (if making fondant-style glaze)
The topping adds shine and bold coffee flavor.
Step-by-Step Coffee Eclair Recipe
Step 1: Make the Pâte à Choux
- In a saucepan, combine butter, water, and salt. Bring to a boil.
- Add flour all at once, stir vigorously until a dough ball forms and pulls away from the pan.
- Transfer dough to a mixing bowl; beat to release steam.
- Add eggs one at a time until the dough is glossy and pipeable.
Step 2: Pipe & Bake Coffee Eclair Shells
- Pipe oblong shapes onto parchment using a star or round nozzle.
- Bake at 200°C (390°F) for 10 minutes, then reduce to 170°C (340°F) for 20–25 minutes until golden and hollow.
- Cool completely before filling.
Step 3: Make Coffee Pastry Cream
- Heat milk with instant espresso powder until steaming.
- Whisk egg yolks, sugar, and cornstarch in a bowl.
- Temper eggs with hot milk, then return to saucepan.
- Cook until thickened.
- Chill under plastic wrap pressed against the surface to prevent skin.
Step 4: Fill the Coffee Eclairs
Either slice shells lengthwise and pipe cream inside, or inject filling with a piping nozzle.
Step 5: Prepare Coffee Ganache / Glaze
- Heat cream, stir in chocolate and espresso powder until smooth.
- Dip the tops of eclairs or spread with a spatula.
Step 6: Assemble & Serve
- Let glaze set.
- Garnish with cocoa nibs, coffee beans, or chocolate curls for presentation.
How to Make the Perfect Pistachio Eclair
Troubleshooting Coffee Eclairs
- Collapsed shells: Usually caused by underbaking or excess liquid. Bake longer at lower heat.
- Flat eclairs: The dough may be too runny; check egg ratio.
- Soggy texture: Always cool shells fully before filling, and avoid overfilling with cream.
- Grainy pastry cream: Cook gently while whisking; strain if necessary.
- Dull glaze: Ensure the ganache ratio has enough fat for shine.
