Very tasty, crumbly cookies with a crispy chocolate crust and chocolate filling. For chocolate lovers, this cookie is a godsend! I recommend everyone to try this cookie, it's a real treat!
One hard-boiled egg. All we need is the yolk.
Divide the remaining two eggs into whites and yolks.
Whisk the yolks white with a whisk with sugar and vanilla. Add the boiled yolk and mix.
Add soft butter, whisk with a whisk or mixer until smooth.
Add flour. Knead the non-sticky dough.
Divide the dough into small balls the size of a yolk.
Put a small piece of chocolate in each ball.
Dip the balls in the egg whites.
Then roll in a mixture of cocoa and powdered sugar. If there is suddenly no powdered sugar in the house, it can be replaced with sugar. It turns out too tasty.
Place the cookies on a baking sheet lined with parchment.
Bake at 170 degrees for 20 minutes.
