Mix oil, liquid chocolate and sugar with mixer, then add eggs one by one. Finally, add flour, baking powder and salt. Place in the refrigerator for a few hours or overnight.
To bake: drop the dough by teaspoonfuls into the powdered sugar, roll over and form balls by hand (mine are 3 cm in diameter and grow to 5 cm when baked). I always put 4 diagonally on the baking sheet and 5 rows under each other.
Bake at 180 °C for about 15 minutes (not too long, they should stay soft inside).
They look good because the powdered sugar cracks during baking, taste great and keep for a long time in the tin.
Tip: Use better chocolate – the more delicious the result!
