STEP 1/6
Place flour, sugar powder, cocoa powder, and cold butter in a cutter and heat for 20 seconds.
STEP 2/6
Add egg yolk and turn cutter until dough is lightly clumped. (If the dough doesn't clump well, add a little milk or water and return it.)
STEP 3/6
Transfer the dough to a bowl and knead lightly with chocolate chips and Hagel Sugar.
STEP 4/6
Place the dough on the wrap and shape it into a cylinder. (It is convenient to put the dough wrapped in the wrap in the wrap core and shape it.) Rest in the freezer for 1 to 1 hour and 30 minutes.

Roll the dough cut to 1cm thickness and coat with white sugar evenly.
STEP 6/6
Bake panned dough in a preheated oven at 180 degrees for 15 minutes.
