Ingredients You’ll Need
These ingredients are simple yet essential, each playing a crucial role in achieving the perfect taste, texture, and visual appeal of your eclairs. From the richness of whole milk to the aromatic vanilla bean seeds, every component brings its own magic to this recipe.
- 4 large egg yolks: Provide creaminess and help thicken the custard for a luscious filling.
- 3 tablespoons cornstarch: Acts as a thickening agent to achieve that smooth custard texture.

- 1/2 cup granulated sugar: Sweetens the custard for just the right balance of flavor.
- 1 tablespoon unsalted butter: Enhances flavor and gives the custard a silky finish.

- Seeds scraped from 1/2 vanilla bean: Adds an intense, natural vanilla flavor and pretty specks in the custard.
- Small pinch salt: Balances sweetness and deepens flavor.
- 1 batch choux pastry: The light and puffed shell that holds the custard—a classic foundation of eclairs.
- Egg wash: 1 egg beaten with 1 tablespoon milk or water, used to give the pastry a golden, shiny crust.

- 4 ounces semi-sweet chocolate: Chopped finely for making that luscious, glossy ganache to coat the eclairs.
How to Make Homemade Eclairs with Vanilla Custard and Chocolate Ganache Recipe
Step 1: Prepare the Vanilla Custard
Start with whisking together cold or room temperature egg yolks and cornstarch until it forms a thick, combined mixture. Then, in a saucepan, heat the milk and sugar until it dissolves and gently simmers. Temper the egg mixture by slowly adding the warm milk while whisking constantly to prevent scrambling. Return this blend to the heat and whisk until it thickens into a creamy custard, usually when large bubbles surface. After removing from heat, stir in butter, vanilla extract, vanilla bean seeds, and salt. Chill your custard in the fridge for at least 3 hours, or up to 24 hours, to develop a rich and firm texture perfect for filling your eclairs.
Step 2: Prepare the Choux Pastry Dough
Follow your favorite choux pastry recipe through the initial stages, ensuring you have a smooth dough ready. This dough is the shell for your eclairs, known for its ability to puff up just right when baked. You can proceed immediately or refrigerate the dough for up to 3 days if you’re prepping in advance.
Step 3: Prepare the Baking Environment
Preheat your oven to 400°F (204°C) and line two baking sheets with parchment paper. Lightly brush the parchment with water to create a humid environment, which encourages the pastry shells to puff up beautifully without drying out or browning too quickly—a simple step with amazing results.
Step 4: Pipe the Eclair Logs
Transfer the choux dough into a piping bag fitted with a large tip, like an Ateco #809, and pipe 4-inch logs spaced 3 inches apart onto the baking sheets. Smooth any peaks or rough edges with a water-moistened finger for even baking. Brush each log lightly with egg wash to achieve that golden brown finish once baked.
Step 5: Bake Your Pastry Shells
Bake at 400°F for 20 minutes, then lower the temperature to 350°F (177°C) without opening the oven door. Continue baking for another 8–12 minutes until the shells are golden and crisp. Avoid opening the oven early to prevent deflation. Once done, transfer the shells to a rack and let cool completely before filling.
Step 6: Make the Chocolate Ganache
Place finely chopped chocolate in a bowl. Heat heavy cream just until it simmers gently—avoid boiling. Pour the hot cream over the chocolate and let sit for a few minutes to soften. Stir slowly until silky smooth and combined. Allow the ganache to cool for 15 minutes; it should thicken to a perfect dipping consistency to coat your eclairs beautifully.
Step 7: Assemble Your Homemade Eclairs with Vanilla Custard and Chocolate Ganache Recipe
Once your pastry shells are cooled and custard chilled, fill a piping bag fitted with a small tip with your custard. Gently fill each eclair, ensuring they are generously stuffed. Then dip or drizzle the tops with your luscious chocolate ganache. Refrigerate until the ganache sets, about 30 minutes, and get ready to enjoy the fruit of your labor!
How to Serve Homemade Eclairs with Vanilla Custard and Chocolate Ganache Recipe

Garnishes
Add a sprinkle of powdered sugar or a few delicate chocolate shavings on top to elevate your eclairs’ appearance, making them look like they belong in a fancy patisserie window. Fresh berries on the side can also add a burst of color and a hint of tartness that contrasts wonderfully with the rich custard and ganache.
Side Dishes
Serve these eclairs alongside a cup of freshly brewed coffee, tea, or even a glass of champagne for a special occasion. Their lightness pairs well with hot beverages that complement the sweetness without overpowering it. A fresh fruit salad can balance the richness for a delightful dessert spread.
Creative Ways to Present
Try arranging your eclairs in a circular pattern on a cake stand with fresh mint sprigs for a charming centerpiece. You can also slice them in half and layer with fresh strawberries for an elevated take. For celebrations, drizzle white chocolate over the ganache or add edible gold flakes to dazzle guests.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store filled eclairs in an airtight container in the refrigerator. They will stay fresh for up to 2 days though they are best enjoyed the day they’re made to retain their crisp shell and creamy filling.
Freezing
You can freeze unfilled choux pastry shells for up to 1 month by placing them on a tray first, then transferring to freezer bags. Thaw and fill them when ready to enjoy freshly assembled eclairs at your convenience. Avoid freezing already filled eclairs, as the custard texture can suffer.
Reheating
To revive the crispness of leftover pastry shells, gently warm them in the oven at 300°F for a few minutes before filling. Avoid reheating filled eclairs as the custard and ganache can melt or become watery. Serving chilled is usually preferred for these delightful treats.
FAQs
Can I use low-fat milk for the custard?
It’s best to stick with whole milk as specified in the Homemade Eclairs with Vanilla Custard and Chocolate Ganache Recipe. Lower-fat milk won’t deliver the same richness and creaminess that makes the custard so satisfying.
How do I prevent the choux pastry from collapsing?
Brushing the parchment with water before baking and avoiding opening the oven during baking are key to keeping the pastry shells puffed up and light. Also, bake them fully until golden brown and crisp to ensure they hold their shape well.
Can I make the vanilla custard ahead of time?
Absolutely! In fact, chilling the custard for at least 3 hours or up to 24 hours enhances the flavor and texture. Just give it a good stir before filling your eclairs for smoothness.
What chocolate works best for the ganache?
Semi-sweet chocolate is ideal because it balances sweetness with slight bitterness, enhancing the overall flavor contrast in your eclairs. You can experiment with bittersweet or milk chocolate depending on your taste.
Is there a way to make the eclairs dairy-free?
This specific recipe relies on dairy for texture and flavor, but you could experiment with plant-based creams and non-dairy milk. However, texture and taste will differ from the traditional Homemade Eclairs with Vanilla Custard and Chocolate Ganache Recipe.
Final Thoughts
Making these Homemade Eclairs with Vanilla Custard and Chocolate Ganache Recipe is one of the most rewarding kitchen adventures you can take. The blend of tender pastry, luscious custard, and silky chocolate ganache creates a harmonious bite that feels truly special.

- 1 teaspoon pure vanilla extract
- Seeds scraped from 1/2 vanilla bean (or extra 1/2 teaspoon vanilla extract)
- Small pinch salt
Choux Pastry
- 1 batch choux pastry (see recipe or pre-made)
- Egg wash: 1 egg beaten with 1 Tablespoon milk or water
Chocolate Ganache
- 1/2 cup (120ml) heavy cream
- 4 ounces (113g) semi-sweet chocolate, finely chopped
Instructions
- Prepare the vanilla custard: In a large heatproof bowl, whisk together the egg yolks and cornstarch until thick and combined. Heat the milk and sugar in a saucepan over medium heat until sugar dissolves and the mixture simmers gently. Slowly pour the warm milk mixture into the egg yolks, whisking continuously to temper the eggs. Strain back into the saucepan and cook over medium heat, whisking constantly until the custard thickens and bubbles, reaching about 185–190°F (85–88°C). Remove from heat and stir in butter, vanilla extract, vanilla bean seeds, and salt. Chill in the refrigerator for at least 3 hours or up to 24 hours.
- Prepare the choux pastry dough: Make the dough through step 4 of your choux pastry recipe. The dough can be piped immediately or refrigerated for up to 3 days.
- Preheat oven and prepare baking sheets: Set oven to 400°F (204°C). Line two baking sheets with parchment paper and lightly brush with water to create humidity, helping the pastries puff without drying.
- Pipe the eclairs: Transfer choux pastry dough to a piping bag fitted with a large tip (Ateco #809 recommended). Pipe 4-inch logs spaced 3 inches apart on the prepared sheets. Smooth peaks using a water-moistened finger and brush lightly with egg wash.
- Bake the pastry shells: Bake at 400°F for 20 minutes, then reduce oven temperature to 350°F (177°C) and bake 8–12 more minutes until golden brown. Avoid opening the oven to maintain puffiness. Cool on a rack completely.
- Make the chocolate ganache: Place chopped chocolate in a bowl. Heat heavy cream in a saucepan until just simmering. Pour over chocolate and let sit 2–3 minutes before stirring until smooth. Cool for 15 minutes until the ganache thickens appropriately for dipping.
- Assemble the eclairs: (Instructions missing in original text but based on standard method) Slice cooled pastry shells horizontally, pipe or spoon chilled vanilla custard inside, then dip the top halves in chocolate ganache or spread ganache on top. Allow ganache to set before serving.
Notes
- Be sure to use whole milk for the custard; low-fat or nondairy milks will affect texture and flavor.
- Brushing parchment paper with water helps create steam for better puffing during baking.
- Keep the oven door closed during baking to prevent pastry collapse.
- Chilling the custard improves the texture and flavor development.
- The chocolate ganache consistency may vary; cool it to thicken before coating the eclairs.
- Choux pastry can be made in advance and frozen before baking for convenience.
