Instructions

• 
  Take the butter out of the fridge in advance so that it softens.
  
• 
  Preheat your oven to 180°C.
  
• 
  In a bowl where you have softened the butter to a cream, add the egg, then the almond powder, sweetener, flavorings and yeast.
  
• 
  Mix with a spatula until you obtain a smooth and homogeneous paste.
  
• 
  Pour the dough into an 8-9cm diameter ramekin and cook for 20-25 minutes at 180°C, monitoring the cooking.
  
• 
  Unmold straight out of the oven and leave to cool on a rack so that the crust hardens.
