Easy Eclair Donuts

Craving eclair donuts? This homemade recipe combines buttery choux pastry, silky vanilla cream, and rich chocolate glaze for bakery-perfect results every time.

What Makes These Eclair Donuts So Irresistible?

These eclair donuts transform classic French choux pastry into elongated, cream-filled pastries featuring buttery shells, smooth vanilla pastry cream, and glossy dark chocolate ganache glaze—creating that perfect balance of crispy exterior and luscious, custardy filling that makes every bite utterly addictive.

Picture this: golden pastry shells so light they practically float off the baking sheet, filled with the creamiest vanilla custard you’ve ever tasted, then dipped in glossy chocolate that sets with that satisfying crack when you bite through. That’s what you’re about to create with this eclair donut recipe.

I stumbled onto these beauties after a particularly disappointing bakery visit where I paid $6 for what turned out to be a sad, cream-less eclair. That night, I decided enough was enough—I was making my own. Now they’re my go-to impressive dessert, and honestly, they’re easier than you’d think.

Why You’ll Love This Homemade Eclair Donut Recipe

Chocolate eclair donuts might sound fancy, but they’re surprisingly approachable once you understand the technique. Here’s why you’ll be making these on repeat:

They’re impressively elegant yet totally doable. I’m talking bakery-quality results without culinary school. The choux pastry looks intimidating, but it’s really just a quick stovetop stir-and-bake situation.

That texture combination is unbeatable. Crispy, golden shell meets silky custard meets rich chocolate. It’s the holy trinity of dessert textures, and each bite delivers all three.

You control the quality. Real vanilla extract, good butter, quality chocolate—you know exactly what’s going into these beauties. No mystery ingredients or artificial flavors here.

They’re fresher than anything you’ll buy. There’s truly nothing like biting into a just-filled eclair with cream that’s still slightly cool and chocolate that’s barely set. According to King Arthur Baking, choux pastry is one of the most satisfying techniques to master because the transformation from batter to puffed pastry is so dramatic and rewarding.

I learned the hard way that patience with the pastry cream is key. My first batch, I rushed the cooling process and ended up with runny filling that leaked everywhere. Now I know—let that cream chill completely, and you’ll have picture-perfect results.

How to Make Perfect Eclair Donuts Step-by-Step

Ready to create these chocolate eclair donuts? Let’s do this together—I’ll walk you through every step like we’re baking side by side.

Making the Choux Pastry Shells

1. Preheat your oven to 350°F and line a baking sheet with parchment paper. Trust me, don’t skip the parchment—these babies will stick otherwise.

2. In a medium saucepan, combine 1 cup milk, 4 tablespoons butter, ¼ teaspoon salt, and 2 tablespoons sugar. Bring the mixture to a rolling boil over high heat, stirring occasionally until the butter melts completely into the milk.

3. The moment it boils, dump in all the flour at once (yes, all of it!) and stir vigorously with your wooden spoon. Lower the heat to medium-low and keep stirring until the mixture pulls away from the pan sides and forms a cohesive dough ball—about 1 minute. Keep cooking and stirring for another minute to eliminate that raw flour taste.

4. Transfer the hot dough to a bowl and let it cool for 3-4 minutes (if it’s too hot, you’ll scramble the eggs). Add one egg to the warm dough, stirring hard with your wooden spoon or hand mixer. The dough will look broken and clumpy at first—don’t panic, this is normal.

Keep mixing until it comes together smooth and glossy, then repeat with the remaining three eggs, one at a time. Your finished choux paste should be thick, smooth, and fall slowly from the spoon in a V-shape.

5. Transfer the dough to a pastry bag fitted with a 1-inch plain or star tip. Pipe 4 to 5-inch straight lines onto your prepared baking sheet, spacing them about 2 inches apart (they’ll puff up significantly).

6. Bake for 40-45 minutes until the eclair shells are deeply golden brown and sound hollow when tapped. Don’t open the oven door for the first 30 minutes or they might collapse. When they’re done, use a small paring knife to poke a slit at each end to release steam—this keeps them crispy and creates your filling entry points.

7. Let the shells cool completely on a wire rack before filling. Seriously, don’t rush this—warm shells will melt your pastry cream into soup.

Creating the Silky Pastry Cream

8. In a medium saucepan, heat 2 cups milk and 1 teaspoon vanilla extract until it just begins to simmer with tiny bubbles around the edges.

9. While the milk heats, whisk together 5 egg yolks, ½ cup sugar, 2 tablespoons flour, and 2 tablespoons cornstarch in a heatproof bowl until the mixture turns pale yellow and smooth (about 1 minute of vigorous whisking).

10. Slowly pour the hot milk into the egg mixture while whisking constantly—this is called tempering, and it prevents scrambled eggs. Go slow and steady, whisking the whole time.

11. Pour the entire mixture back into the saucepan and cook over medium heat, stirring constantly with a whisk or wooden spoon. The mixture will thicken suddenly—keep stirring and let it bubble and boil for 1 full minute. This activates the starches for proper thickening, and don’t worry, the flour and cornstarch protect the eggs from curdling.

12. Remove from heat immediately and stir in 4 tablespoons cold cubed butter until melted and incorporated. Transfer the pastry cream to a clean bowl and press plastic wrap directly onto the surface to prevent skin formation. Refrigerate until completely cold—at least 2 hours or overnight.

13. Once chilled, transfer the pastry cream to a pastry bag fitted with a filling tip. Insert the tip into the knife slits at each end of an eclair shell and squeeze gently to fill—you’ll feel the shell getting heavier. Fill from both ends to ensure cream throughout the entire pastry.

Making the Chocolate Glaze

14. Chop 4 ounces dark chocolate into small, even pieces for smooth melting. Place the chocolate, 2 tablespoons corn syrup, and 2 tablespoons heavy cream in a heatproof bowl.

15. Set the bowl over a saucepan of gently simmering water (don’t let the bowl touch the water). Stir occasionally as the chocolate begins melting, then whisk until completely smooth and glossy. If the glaze thickens too much while working, add another tablespoon of cream and rewarm briefly.

16. Dip the top of each filled eclair into the warm chocolate glaze, letting excess drip off. Use a butter knife to smooth if needed. Let the glaze set at room temperature for about 10 minutes before serving.

Pro Tips for Eclair Donut Success

Homemade eclair donuts require a few key techniques, and I’ve learned these lessons through plenty of trial and error:

Room temperature eggs are essential. Cold eggs don’t incorporate smoothly into warm choux paste, creating a lumpy, uneven dough that won’t puff properly. According to Serious Eats, eggs should be around 70°F for optimal emulsification—temperature differences greater than 15°F can cause the paste to break, resulting in flat, dense pastries instead of airy puffs.

Don’t open the oven door early. I know it’s tempting to peek, but that rush of cool air can deflate your beautiful puffs. Wait at least 30 minutes before checking—the structure needs time to set.

Pastry cream must boil to thicken. This seems counterintuitive since we’re taught eggs curdle when boiled, but the flour and cornstarch protect them. If you don’t bring it to a full boil for at least 1 minute, you’ll end up with runny cream that won’t hold its shape inside the eclairs.

Use a filling tip with a narrow opening. Regular round tips are too wide and will tear your shells. A proper eclair filling tip (sometimes called a Bismarck tip) lets you fill without creating huge holes.

Troubleshooting Common Eclair Problems

Why did my eclair shells collapse after baking? They weren’t baked long enough to set the structure. Choux pastry needs deep golden color and a hollow sound when tapped—pale eclairs haven’t developed enough strength. Also, make sure you poked steam holes immediately after removing them from the oven.

My pastry cream turned out lumpy. What happened? Either you didn’t whisk constantly while cooking, or the mixture got too hot too fast. Next time, push the finished cream through a fine-mesh sieve to remove any bits. The texture will still be delicious.

The chocolate glaze is too thick to dip. Add another tablespoon of heavy cream and gently rewarm the glaze over the double boiler while stirring. Chocolate glazes can seize up if they cool too much or if water gets into the mixture.

Can I make the components ahead? Absolutely! Bake the shells up to 2 days ahead and store in an airtight container at room temperature. Make the pastry cream up to 3 days ahead and refrigerate. Only fill and glaze the eclairs within a few hours of serving for the crispiest shells.

For an elegant twist, swap the classic vanilla filling or chocolate glaze with our pistachio buttercream—silky, nutty, and insanely good piped into or on top of eclairs.

Creative Variations and Flavor Twists

Eclair donut recipe variations are where you can really have fun:

Coffee Eclairs: Add 2 tablespoons instant espresso powder to the pastry cream for a sophisticated mocha flavor. Top with coffee-infused chocolate glaze by mixing 1 teaspoon instant espresso into the melted chocolate.

Raspberry Eclairs: Fold ¼ cup raspberry puree into the finished pastry cream for a fruity twist. Top with white chocolate glaze instead of dark chocolate for beautiful contrast.

Chocolate Pastry Cream: Replace 2 tablespoons of flour in the pastry cream with 2 tablespoons cocoa powder for double chocolate decadence.

Matcha Eclairs: Whisk 1 tablespoon matcha powder into the pastry cream for an elegant green tea flavor. Top with white chocolate glaze.

How to Serve, Store, and Keep Eclairs Fresh

Serving: These chocolate eclair donuts are best enjoyed within 4-6 hours of filling for maximum crispness. Serve them slightly chilled so the pastry cream is firm and refreshing against the room-temperature chocolate glaze.

Storage: Store filled eclairs in a single layer in an airtight container in the refrigerator for up to 2 days. The shells will soften as they sit, but they’ll still taste incredible. Unfilled shells can be stored at room temperature in an airtight container for 2 days or frozen for up to 1 month.

Refreshing: If your eclair shells have softened in the fridge, pop them (unfilled) into a 300°F oven for 3-4 minutes to crisp up before filling.

Zero-Waste Kitchen Ideas

Don’t toss those extra egg whites from making pastry cream! Here are some delicious ways to use them:

Whip them into meringues for a simple, sweet treat—pipe small kisses and bake low and slow at 200°F until crisp.

Make a French omelet for tomorrow’s breakfast using 3-4 egg whites with one whole egg for richness.

Freeze them in ice cube trays with 1 egg white per cube, then transfer to a freezer bag. They’ll keep for 3 months and thaw perfectly for future baking projects.

Create a clarifying face mask by whisking one egg white with a teaspoon of honey (yes, really—it’s a time-honored beauty trick).
