Stir pudding powder, 3 tablespoons sugar and 100 ml milk until smooth. Bring 300 ml milk to the boil in a saucepan, remove from the heat and stir in the custard powder. Place back on the hot stove and simmer for about 1 minute while stirring. Put the pudding into a bowl, cover the surface directly with foil and let it cool down
Bring 125 ml milk, 125 ml water, salt and fat to the boil in a saucepan. Add the flour at once and stir with a mixing spoon until the dough separates as a lump from the bottom of the pot. Put the dough into a mixing bowl and immediately stir in 1 egg. Leave to rest for approx. 5 minutes, then stir in the remaining eggs one by one
Place the choux pastry in a piping bag with a large perforated nozzle (1.5 cm Ø). Spray 8 thick strips (eclairs) of approx. 10 cm each onto 2 baking trays (approx. 34 x 41 cm) lined with baking paper. Bake in the preheated oven, 2nd shelf from below (electric oven: 225 °C/ convection oven: 200 °C/ gas: see manufacturer) for 25-30 minutes. After approx. 5 minutes, turn the oven on (electric oven: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) and finish baking. Remove the eclairs from the oven and immediately cut them in half horizontally with scissors. Let them cool down on a cake rack
Break the chocolate into pieces and put it in a pot with 100 g cream and coconut oil. Melt at low heat while stirring. Let the glaze cool down for 10-15 minutes. Coat the upper halves of the eclairs with the icing and let them dry
Whip 400 g cream with the whisk of the hand mixer until stiff, allowing the cream firmer to trickle in. Stir the pudding briefly with the whisks of the hand mixer. Add 2/3 of the cream and stir in. Fold in the remaining third of the cream and refrigerate for approx. 10 minutes
Wash the strawberries, drain well and clean. Cut the strawberries into pieces, sprinkle with 1-2 tablespoons of sugar and leave to stand for 5-10 minutes
Pour the pudding cream into a piping bag with a large star-shaped spout and squirt it onto the lower halves of the eclair in a cord-like manner. Spread strawberries on top and place the chocolate lid on top. Serve immediately
