Start by preparing the choux pastry: in a large pan, mix the water, milk, sugar, salt and butter then put it on high heat and bring it to a rolling boil.

Add the sifted flour and stir it in with a wooden spoon until smooth.

Cook it for 1 minute stirring constantly, until the mixture leaves the sides of the pan.

Transfer this to the bowl of your standing mixer and let it cool down.

In a separate bowl, beat your eggs lightly, then fit the stand mixer with the paddle attachment and gradually beat the eggs in. Be careful not to add too much or too little egg: the dough has to have a dropping consistency and has to be shiny and glossy.

Now that you're ready, fill a piping bag and pipe 2.5cm rounds on some parchment paper, and bake the choux pastry for 15 minutes at 200C, then drop the temperature to 165C and cook for a further 10-15 minutes, or until the buns are golden. Set aside and let them cool down completely before filling.

Time for the matcha filling: beat all the ingredients until soft peaks form and you're ready to fill - fill a piping bag fitted with a nozzle and set aside.

Fill each puff with the piping bag, from the bottom, until they feel quite full.

In a separate bowl prepare the matcha shell: melt the white chocolate and coconut oil, then add the matcha powder and stir.

Dip each matcha puff and serve them immediately or store in the fridge for up to three days.
