Marble Cookies

Made some years ago. Followed the below recipe, which works perfectly well. Pinch of salt is key.

recipe:
butter ........... 125 gm
salt .......... a pinch
sugar .......... 60 gm
egg yolk .......... one
milk .......... 1 tsp

2/3 of the above mixture into the original dough:
cake flour ........... 130 gm
baking powder .......... 1/3 tsp

1/3 of the above butter mixture into the coco dough:
cake flour ..........55 gm
coco powder .......... 10 gm
baking powder .......... 1/4 tsp

Freeze the doughs for ca. 3 hours before working. Bring them out when ready. Break the coco dough into smaller bits; mixed them together with the original dough and shape it into a roll of ca. 4cm dia.

Wrap the roll up with a plastic wrap, twist it carefully to achieve the beautiful swirling effect. Mind you, the plastic wrap may break after your twisting.

Put it away in the fridge for abt 30 min or so before cutting it into pieces for baking, at 180 deg C, for 12 min or until golden brown. Taste wonderful. Use the best coco powder which makes a huge difference.
