Ingredients You’ll Need
Gathering the right ingredients is the secret to nailing this Mocha Éclairs Recipe. Each component plays an important role in creating that light, airy texture and luscious mocha flavor that define these éclairs.
- All-purpose flour (1 cup): The backbone of the pastry dough; provides structure for those beautiful puffy shells.
- Unsalted butter (1/2 cup): Adds richness and helps create that flaky, golden crust.
- Large eggs (4): Responsible for the airy rise and glossy finish of the pâte à choux.
- Whole milk (1 cup): Creamy base for the mocha filling, contributing to smooth texture and flavor.
- Granulated sugar (1/2 cup): Sweetens both the filling and pastry, balancing mocha’s slight bitterness.
- Unsweetened cocoa powder (1/4 cup): Gives deep chocolate notes that marry wonderfully with coffee.
- Instant coffee granules (2 tbsp): Infuses that unmistakable mocha essence without overpowering.
- Heavy cream (1 cup): Whipped to top the éclairs, adding lightness and a creamy finish.
- Dark chocolate chips (1/2 cup): For melting into the filling or optional drizzle, enriching the chocolate flavor.
How to Make Mocha Éclairs Recipe
Step 1: Prepare the Pastry Dough
Start by preheating your oven to 425°F (220°C). In a saucepan, heat water and your unsalted butter together until they reach a rolling boil. Once boiling, stir in the all-purpose flour vigorously until the dough forms a smooth, cohesive ball. This step is crucial to ensure the pâte à choux has the perfect elasticity and consistency for puffing up during baking.
Step 2: Incorporate the Eggs
Let the dough cool slightly so it doesn’t cook your eggs. Then, add in the eggs one at a time, mixing well after each addition. The dough should transform into a glossy, smooth batter that’s sticky but holds its shape. This silky dough is what ensures your éclairs will have that signature hollow interior.
Step 3: Pipe the Éclairs
Fit a piping bag with a large round tip and pipe the dough into 4-inch logs on parchment-lined baking sheets. Keep your piping motions steady and even, as uniformity here translates to uniformly baked éclairs that look stunning on the plate.
Step 4: Bake to Golden Perfection
Bake the pastry logs for 25 to 30 minutes or until they puff up beautifully and take on a golden brown color. Resist the temptation to open the oven door during baking, as this can cause them to collapse. The dry heat inside the oven will create that lovely hollow center you’re aiming for.
Step 5: Make the Mocha Filling
While your pastry is baking, simmer whole milk and sugar together until hot but not boiling. In a separate bowl, whisk egg yolks with cocoa powder and instant coffee granules until fully combined. Slowly add the hot milk mixture into the egg yolks, whisking constantly to temper the eggs. Return this mixture to the stove and cook gently until it thickens into a creamy mocha custard. Allow this filling to cool completely before using it to stuff the baked shells.
Step 6: Whip the Cream and Assemble
Whip the heavy cream until soft peaks form. Once your éclairs are cool, carefully fill them with the mocha custard using a piping bag, then generously top each with the whipped cream for an airy, luscious finish. Optional melted dark chocolate can be drizzled on top to intensify the chocolate experience.
How to Serve Mocha Éclairs Recipe

Garnishes
For an elegant touch, dust your finished mocha éclairs with a light sprinkling of cocoa powder or powdered sugar. Fresh coffee beans or shaved dark chocolate add flair and deepen the sensory invitation your dessert offers. These garnishes not only heighten the visual appeal but reinforce the mocha flavor theme.
Side Dishes
Serve these éclairs alongside a steaming cup of espresso or a rich cappuccino to complement the mocha notes. A fresh berry salad can provide a bright contrast, cutting through the richness with natural acidity and freshness. This pairing gives your dessert experience balance and variety.
Creative Ways to Present
For a fun twist, slice the éclairs and layer them in a parfait glass with alternating mocha cream and whipped cream layers. You can also transform them into mini dessert sandwiches, slicing the éclairs horizontally and filling with the mocha custard plus a sprinkle of crushed nuts for texture.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator. Be mindful that the pastry shells may soften after a day or two due to moisture from the filling, but the flavors will remain just as delightful.
Freezing
Freezing filled éclairs is not recommended as the cream filling can alter texture upon thawing. However, you can freeze unfilled baked shells for up to one month. When ready to use, thaw completely and fill just before serving to preserve that fresh, crisp pastry.
Reheating
To enjoy éclairs at their best, allow refrigerated éclairs to come to room temperature before serving. Avoid reheating in the microwave as this can wilt the whipped cream and make the pastry soggy. If you froze unfilled shells, warm them briefly in a low oven before filling.
FAQs
Can I use instant espresso instead of instant coffee granules?
Absolutely! Instant espresso can intensify the mocha flavor even more. Just use an equal amount in place of coffee granules to keep the balance right.
What if I don’t have a piping bag?
No worries! You can use a zip-top bag with a small corner snipped off to pipe the dough and filling. It’s a simple hack that works beautifully for shaping éclairs.
Can I substitute heavy cream with something lighter?
Heavy cream is key for that rich and stable whipped topping, but you can try whipping full-fat coconut cream as a dairy-free alternative, keeping in mind the flavor will be subtly different.
Is there a way to make the éclairs less sweet?
Yes, you can reduce the granulated sugar slightly in the filling or skip adding extra sugar to the whipped cream if you prefer a less sweet mocha éclair. Just be careful not to cut sweetness too much so the flavors stay balanced.
How do I keep my éclairs from deflating?
The main trick is not to open the oven door during baking, especially in the first 20 minutes. Also, make sure your dough is cooked properly on the stovetop before adding eggs to give it the structure needed to rise and hold shape.
Final Thoughts
Making this Mocha Éclairs Recipe is a rewarding way to bring a taste of French patisserie into your own home, with a comforting coffee and chocolate twist.

Ingredients
Choux Pastry
- 1 cup all-purpose flour
- 1/2 cup unsalted butter
- 4 large eggs

Topping
- 1 cup heavy cream
- 1/2 cup dark chocolate chips
Instructions
- Prepare Choux Pastry: Preheat your oven to 425°F (220°C). In a saucepan, heat water and the unsalted butter until the mixture boils. Remove from heat and immediately stir in the all-purpose flour vigorously until the mixture forms a smooth dough that pulls away from the sides of the pan.
- Incorporate Eggs: Allow the dough to cool slightly to avoid cooking the eggs when added. Add the eggs one at a time, mixing thoroughly after each addition until the dough becomes smooth, glossy, and slightly thickened, indicating it is well combined.
- Shape Éclairs: Transfer the dough to a piping bag fitted with a large round tip and pipe 4-inch logs onto parchment-lined baking sheets, spacing them apart to allow room for expansion.
- Bake Éclairs: Bake in the preheated oven for 25-30 minutes or until the éclairs are puffed up and golden brown. Avoid opening the oven door during baking to prevent deflation.
- Prepare Mocha Filling: In a saucepan, gently simmer the whole milk with granulated sugar until warm. In a separate bowl, whisk together the egg yolks with the unsweetened cocoa powder and instant coffee granules until smooth. Gradually combine the warm milk into the egg mixture, then return the mixture to the saucepan and cook over low heat, stirring constantly until it thickens to a custard-like consistency. Remove from heat and cool completely before use.
- Whip Cream Topping: Whip the heavy cream until soft peaks form. Optionally, melt the dark chocolate chips for drizzling or incorporate them into the topping as a garnish.
- Assemble Éclairs: Once the éclairs and mocha filling are cooled, carefully slice each éclair horizontally and fill with the mocha cream custard. Top with whipped cream and optionally drizzle with melted dark chocolate for an elegant finish. Serve immediately or chill briefly before enjoying.
Notes
- Do not open the oven door during baking to ensure éclairs puff properly.
- Cool the custard filling thoroughly to prevent it from melting the pastry.
- For best texture, pipe the dough onto parchment paper to avoid sticking.
- You can substitute instant coffee with espresso powder for a more intense coffee flavor.
- Dark chocolate chips can be melted and drizzled over the éclairs for added richness.
