Put the chosen oil, the 200g of egg (about 4 medium eggs), the washed and chopped parsley and the peeled garlic into a blender and blend until you have a kind of homogeneous cream.
Pour into a bowl and add the milk, salt and sugar.
Mix, then add the flour, baking powder and hazelnut powder.
Then add the cheeses: grated Emmental or Comté, and morbier cut into pieces (with the rind!).
Mix well, then pour into the baking tin lined with baking parchment. Drizzle a little oil over the inside edge to facilitate removal from the mold.
Bake for 50 minutes at 175°C over static heat (not convection heat).
Turn out and leave to cool on a wire rack.
Enjoy as an aperitif or starter with a salad. Morbier cake tastes best warm or lukewarm, so all you have to do is heat it up!
