Ferrero Rocher éclairs

Ferrero Rocher éclairs

Ambassador, with these Ferrero Rocher éclairs you are really spoiling us! Based on the classic chocolate treats, these éclairs are filled with a rich Nutella mousse and topped with milk chocolate and chopped hazelnuts.

  1. Step 1

    Preheat the oven to 200ºC/180°C fan/gas mark 6 and line two large baking trays with greaseproof paper. Draw 12 roughly 10cm long lines on the paper to use as guidelines
  2. Step 2

    For the choux pastry, combine the water, butter and salt in a saucepan. Gently melt the butter over a low heat without bringing the mixture to the boil (you want the butter to be just melted, and avoid evaporating too much of the water)
  3. Step 3

    Once the butter has melted, bring the mixture up to the boil and tip all the flour into the pan in one go. Remove the pastry from the heat
  4. Step 4

    Use a wooden spoon to beat the mixture as fast as you can, bringing it all together into a dough that pulls away from the sides of the pan
  5. Step 5

    Once the dough starts to pull away, return the choux pastry to the heat and continue cooking and stirring the dough (no need to beat it as frantically at this stage) until an instant read thermometer reads 74°C. A little above this temp is fine as well. If you don’t have a thermometer, continue cooking the dough until the base of the saucepan is covered in a fine film of pastry
  6. Step 6

    Remove the dough from the pan and transfer it to the bowl of a stand mixer with a paddle attachment (or another bowl if using a wooden spoon) to cool a little. It helps to spread the dough out at this stage to cool it faster
  7. Step 7

    Once the dough reaches 63°C or cooler, it’s time to add the eggs. Lightly beat the eggs together in a jug
  8. Step 8

    Mix the dough on low speed, and gradually beat the eggs into the dough, ensuring each addition is fully incorporated before adding the next. It’s unlikely that you will need all of the egg. Keep adding egg until you have a mixture that reluctantly drops from the paddle, leaving a V shape. Another way to test if the dough is ready is by scooping some up onto a spoon then counting slowly to 6 - it should have dropped by the time you reach 6 (slow) seconds
  9. Step 9

    Dab a few dots of the mixture in each corner of the baking trays to stick the greaseproof paper to the surface of the baking trays
  10. Step 10

    Fit a piping bag with a star nozzle that’s around 1.25cm wide (with a lot of teeth, if possible). Fill the piping bag with the choux pastry
  11. Step 11

    Place the filled piping bag onto a flat surface and carefully flatten the pastry mixture inside, taking care not to squeeze it out of the bag. Using a pastry scraper or other thin, flat object, gently push the choux pastry down into the bag to remove air bubbles and collect all the dough in one place. Twist the bag at the top and pipe a little of the mixture to remove any air bubbles near the tip
  12. Step 12

    Carefully pipe the pastry over the guidelines on the baking paper at a 45 degree angle, if possible. Try to achieve a very slight ‘dog bone’ shape with the pastry, as this will ensure they are more evenly shaped once baked. It’s also important to try to pipe fairly slowly, otherwise the éclairs will be too skinny
  13. Step 13

    Sprinkle a few drops of water around the éclairs (not touching the pastry) and transfer to the oven to bake for 25 minutes. After 25 minutes, swap the trays around for a further 5 minutes, or until the pastry is deep golden brown and crisp – they should sound hollow when tapped
  14. Step 14

    Prick the underside of the éclair shells with a cocktail stick and transfer onto a wire rack to cool completely
  15. Step 15

    To make the Nutella mousse, whip the cream in a stand mixer with a whisk attachment (or an electric whisk) until soft peaks form, then carefully scrape out into a bowl
  16. Step 16

    In the bowl of the mixer, whisk together the icing sugar, vanilla bean paste, cream cheese, Nutella and a pinch of salt then beat on medium high until pale and creamy
  17. Step 17

    Fold in the whipped cream with a rubber spatula until combined
  18. Step 18

    Transfer the Nutella mousse to a piping bag fitted with a fine nozzle and twist the end to seal
  19. Step 19

    Make two holes in the end of the choux pastry cases. Snip off the end of the bag and pipe the mousse into either end of the éclairs, until full
  20. Step 20

    To make the chocolate topping, melt the milk chocolate in a bain-marie and then allow to cool slightly
  21. Step 21

    Dip the pastry cases into the melted chocolate and allow to set for a few minutes before topping with the chopped hazelnuts
