Eclairs with vanilla custard and chocolate sauce

When I decided to make eclairs for my second to last recipe in my 30th birthday countdown, I had no idea how heartbreaking it was actually going to be. But after failing 4 times I decided to give it one last go and there it was, perfectly risen, hollow choux pastries! I’m so glad I didn’t give up, which isn’t something I’ll do easily in general, as I’ve always ‘dusted myself off and tried again’. This was created for my dad, who absolutely loves eclairs and comes from a family with a love for sweets and desserts in general. As long as I can remember, we used to have eclairs at every birthday party, and you can bet they’ll be there on my 30th too!

When it comes to the flavours, I’ve gone for the traditional Belgian way: filled with vanilla custard, topped with chocolate sauce. A lot of bakeries around the world seem to make it with whipped cream inside, some don’t add anything on top either but trust me: you can not beat a vanilla custard eclair dipped in chocolate sauce!

But what made this recipe so hard to make? It’s the damn pastry! I had the custard and chocolate sauce figured out right away, but my first attempts were just disastrous in terms of the pastry. They simply came out of the oven flat every single time! I tweaked the recipe a few time, and if you follow my recipe below exactly, I believe you’ll succeed the first time around as well. It’s safe to say this recipe has been my Everest, the toughest and most heartbreaking one yet but let me tell you: it was all worth it in the end! They were a big hit at home – even after having traveled on a plane to Belgium.

Ingredients:

Adjust Servings
100g unsalted butter
600ml full fat milk
100ml water
150g plain flour
40g corn starch
7 eggs
1tsp vanilla essence
120g caster sugar
150g dark chocolate
150g whipped cream (already whipped)
5tbsp icing sugar
few tablespoons of chocolate sprinkles

Directions

1.
Preheat the oven to 220°C (fan)
Add 100ml water, 100ml milk and 100g butter together with a pinch of salt and half a teaspoon of sugar and bring to a boil so that everything melts nicely.
Take it off the heat and add all the flour at once, stir vigorously with a wooden spoon and stir until it loosens from the side.

Place back at low heat, to dry it up as much as possible - which will allow us to add more eggs later, which will help with the overall result.
It is really important to get as much liquid out of the dough as possible. The drier the dough is, the more eggs we can add and the eggs will help the pastries rise in the oven and give them flavour too.

3.
Mix 5 eggs in a small bowl, this will make it a lot easier to add gradually!
Put your dough in a stand mixer and gradually add the eggs while beating at low speed, stop when you've added about a third and have a look.
You want the pastry to only expand just a tiny bit when you spread it onto a plate. If it's not moving at all and looks dull (instead of glossy), add a bit more egg. I added 4 myself and kept one aside to glaze. If you add too many eggs you can try to add more flour to balance it out.

Use a piping bag to pipe the dough out onto parchment paper.
Mine were about 10-12cm long and 2 cm wide - I used the biggest piping nozzle I had.
I really recommend trying just one before piping them all, if anything has gone wrong you can still try to adjust your ingredients then.

Poke a small hole in one side of the eclairs
Make sure to poke around on the inside a bit too (I used a fondue stick) and let them cool down on a wire rack - the hole will allow for the steam to come out. Wiggling it on the inside will avoid the custard from hitting a pastry wall on the inside.

Moving on to the custard now, the easier part for sure!
Mix 2 egg yolks, 120g sugar, vanilla essence and 40g corn starch in a measuring cup really well to avoid lumps.
Bring 500ml milk to a boil in a little pot, then add just a few tablespoons to the other mixture - adding the hot milk gradually will help avoid lumps too.

Gradually add more hot milk until you're about halfway, then add it all to the pot and stir like crazy!
Increase the heat, it'll thicken the sauce. Stop when you have a thick but smooth mixture.
You don't want it to be too thin or it'll just run right out of your eclairs when filling them. Cover with cling film and place the custard mixture in the fridge until between cold and lukewarm.

Fill up a piping bag with the custard and fill the eclairs up through the little hole we made before.
If you find the end is not filling up, make another small hole on that side and fill from there as well.

Now moving on to the last bit!
Add chocolate and whipping cream to a pot and melt at low heat.
I added some icing sugar as I prefer my chocolate sauce to be sweet, but have a taste and decide for yourself if you want to go that way too.

Dip the eclairs in the sauce, sprinkle the edges with chocolate sprinkles and place on a plate and let the sauce firm up in the fridge.
