Heat until the butter is melted.
Strain into a clean bowl and set aside.
Sift together the flour, sugar and yeast.
In a thermomix, temper the eggs to 30°C and emulsify with the butter mixture. Incorporate the flour mixture until the dough is homongeous.
Pour the dough into small shelf-shaped silicone moulds. Bake without humidity at 177°C for 4 minutes.
Rotate the moulds and bake for 3 more minutes to ensure uniform cooking. Remove the oven and allow to cool, then unfold and serve or store in an airtight container.
