These chocolate eclairs are crisp, hollow choux pastry shells filled with a thick, vanilla-scented whipped cream and finished with a glossy dark chocolate fondant that sets to a smooth, firm coat. The contrast between the light, airy shell and the cold, dense filling makes each bite satisfying without feeling heavy. This version of the Mary Berry chocolate eclairs recipe keeps the method clear and measured, making it well within reach for a home baker who has never worked with choux before.

The recipe produces reliably puffed shells every time, provided the oven temperature is respected and the piping is even. The filling can be made ahead, and the chocolate topping takes just minutes to prepare. From start to finish, the whole recipe is ready in around 1 hour and 15 minutes.

How to Make Mary Berry Chocolate Eclairs

01
Prepare the oven and baking tray:
Heat the oven to 200°C (180°C fan, Gas 6) and lightly grease two large flat baking trays. Line them with baking parchment and set aside. A well-greased, lined tray allows the shells to release cleanly once baked, without tearing the base.
02
Make the choux pastry:
Place the water, butter, and salt in a medium saucepan over a medium heat. Stir occasionally until the butter has fully melted, then bring the mixture to a rolling boil. Remove the pan immediately from the heat and tip in all the sifted flour at once. Beat vigorously with a wooden spoon until the mixture pulls away from the sides of the pan and forms a smooth ball. Leave to cool for five minutes before adding the eggs, as adding them too early will begin to cook the egg and result in an uneven dough.
03
Incorporate the eggs:
Add the beaten eggs to the dough a little at a time, beating firmly between each addition until the paste is smooth, shiny, and falls slowly from the spoon in a thick ribbon. It should hold its shape when piped. If the dough looks very stiff after all the egg is added, beat for another 30 seconds.
04
Pipe the eclair shells:
Spoon the choux paste into a large piping bag fitted with a 1.5cm plain round nozzle. Pipe lines approximately 10cm long onto the prepared trays, spacing them at least 5cm apart to allow for expansion. Dampen a fingertip and smooth any peaks at the ends of each line to prevent them from burning before the rest has baked through.
05
Bake until golden and hollow:
Place the trays on the top and middle shelves and bake for 25 to 28 minutes, until the shells are a deep golden brown and feel firm and hollow when tapped on the base. Do not open the oven door during the first 20 minutes, as the sudden drop in temperature will cause the shells to collapse before they have fully set.
06
Split and dry the shells:
Remove the trays from the oven and immediately use a small sharp knife to pierce the end of each eclair, then slit them open along one side to release the steam. Return to the oven for a further three to four minutes to dry the insides completely. Transfer to a wire rack and leave to cool fully before filling.
07
Whip the cream filling:
Pour the chilled double cream into a cold bowl and add the icing sugar and vanilla extract. Whisk to soft, billowy peaks that hold their shape without looking grainy or over-beaten. The cream should be thick enough to pipe cleanly but still smooth and light in texture.
08
Fill the eclairs:
Spoon the whipped cream into a piping bag fitted with a small star or plain nozzle. Pipe the cream generously into each cooled shell through the slit along the side, filling from one end to the other until the cream just begins to show at the edges. Do not overfill or the shells will split when the chocolate topping is applied.
09
Make the chocolate topping:
Place the chocolate pieces in a heatproof bowl. Warm the double cream and golden syrup together in a small saucepan until just beginning to simmer, then pour directly over the chocolate. Leave for one minute, then stir from the centre outward until the mixture is completely smooth and glossy. The golden syrup gives the finished topping a shine and prevents it from setting too hard.
10
Top and set:
Dip the top of each filled eclair into the warm chocolate, allowing any excess to drip back into the bowl, then place on a wire rack. Leave at room temperature for 20 to 25 minutes until the chocolate has set to a firm, glossy finish before serving.

Tips for the Best Chocolate Eclairs

01 Why did my choux pastry shells come out flat and dense instead of hollow?

The most common cause is opening the oven door too early, which lets cool air in and causes the unset shells to collapse. Wait at least 20 minutes before checking, and make sure the oven has reached the correct temperature before the trays go in. Shells that are pale or soft when removed from the oven also need more time, not less.

02 Why is my choux paste too runny to pipe into clean lines?

This usually happens when the eggs are added to dough that is still too warm, or when they are added all at once rather than gradually. Allow the cooked paste to cool for at least five minutes before adding any egg, and beat in small amounts at a time until the correct ribbon consistency is reached. A properly mixed paste should fall slowly from the spoon and hold its piped shape on the tray.

03 Why is there soggy, wet dough inside my eclair shells after baking?

The inside of the shell needs to be dried out after baking. Once the shells are golden and firm, pierce and slit them immediately, then return them to the oven for three to four more minutes. This step allows the trapped steam to escape and the interior to crisp up, which prevents the cream filling from soaking through the walls once assembled.

04 Why does my chocolate topping set dull and streaky rather than shiny?

A dull or streaky glaze usually means the cream was either too hot when it hit the chocolate, causing it to seize, or the mixture was stirred too vigorously too soon. Pour hot cream over the chocolate, wait a full minute before stirring, and work from the centre outward in slow, steady circles. Adding a small amount of golden syrup helps the finished glaze hold its shine as it sets.

05 Why does the cream filling collapse or become watery inside the eclairs?

Over-whipped cream that has been beaten past soft peaks can separate and release liquid inside the shell. Stop whipping as soon as the cream holds a soft, drooping peak. Also ensure the shells are fully cooled before filling, as any warmth will melt the cream and cause it to weep through the pastry walls.

Serving Suggestions

✦

Serve chilled from the fridge on a flat white platter, arranged in a single row with the chocolate tops facing upward for a clean, elegant presentation.

✦

Pair alongside a pot of Earl Grey or Darjeeling tea for a classic British afternoon spread.

✦

Dust lightly with a pinch of flaky sea salt over the chocolate topping just before serving to add a subtle contrast to the sweetness.

✦

Serve as part of a celebration dessert table alongside other choux pastries such as profiteroles and cream puffs for a patisserie-style display.

✦

Place on individual dessert plates with a small spoonful of fresh raspberries on the side, as the sharp berry cuts through the richness of the cream and chocolate filling.

◷

Storage

UP TO 2 HOURS

Room Temperature

Once filled and topped, eclairs should be served within two hours if left at room temperature, as the cream filling will begin to soften the pastry shell.

UP TO 24 HOURS

Refrigerator

Store filled eclairs in a single layer in an airtight container in the fridge for up to 24 hours. Remove from the fridge 10 minutes before serving so the chocolate topping loses its brittleness and the cream softens slightly to the right consistency.

UP TO 1 MONTH

Freezing

Unfilled, baked choux shells freeze well. Allow them to cool completely, then place in a sealed freezer bag and freeze for up to one month. Defrost at room temperature for 30 minutes, then crisp in a 180°C oven for five minutes before filling and topping as normal. Do not freeze filled eclairs.

FAQs

01 Can I use milk chocolate instead of dark chocolate for the topping?

Yes, milk chocolate works as a direct swap and produces a sweeter, milder topping. Because milk chocolate has a higher sugar content, it sets slightly softer than dark chocolate, so reduce the amount of golden syrup by half to help it firm up properly.

02 Can I make the choux pastry shells the day before?

Yes, the baked and dried shells can be made up to one day in advance and stored in an airtight tin at room temperature. If they soften overnight, place them on a baking tray in a 180°C oven for five minutes to restore their crispness before filling.

03 Can I use whipping cream instead of double cream for the filling?

Whipping cream can be used and will give a slightly lighter, less rich filling. It whips up quickly, so keep a close eye to avoid over-beating. Double cream is preferred because it holds its shape longer after piping, which is particularly useful if assembling eclairs in advance.

04 Can I make these eclairs gluten free?

Choux pastry can be made with a gluten-free plain flour blend, though the texture of the finished shells may be slightly denser and less crisp than those made with standard plain flour. Use a blend that contains xanthan gum to help the dough hold together during piping and baking. The cream filling and chocolate topping are naturally gluten free.

05 Can I double this recipe to make more eclairs for a party?

The recipe doubles well. Make the choux paste in two separate batches rather than doubling everything in one pan, as a very large quantity of dough is harder to beat evenly and may result in uneven shells. The cream filling and chocolate topping can both be doubled in a single bowl without any issues.
