How to make
Beat the butter with the sugar. Add the egg yolks and continue to beat. Finally, add the sifted flour, cocoa and baking powder.
Knead smooth and soft dough. Tear pieces and shape them into balls the size of a small walnut (28-30 pcs). Arrange them spaced apart on a tray lined with baking paper.
With your finger or a suitable object (I used one of my modeling tools), make an indentation in the middle.
Bake at 360°F (180°C) for about 10-12 minutes. Take them out and leave them to cool.
Melt the chocolate, leave it to cool slightly and decorate the cookies using a piping bag. Pour the strawberry jelly into the indentation.
