One dough, two different flavors. Effective looking cookies, yet very simle to make. And also very delicious!!!
Note 1.
Since there is a difference in European and US measurement, I always suggest to use the kitchen scale.
Note 2.
There are 3 ways you can achieve that marble effect:
The first way is by using your hands to take pieces of each dough alternately and with your palms to shape a ball.
The the second way is a very long way - put the dough in the refrigerator for 30 minutes. Then make two logs, one log of each dough. Then chill dough logs again for 30 minutes. Place chilled logs side by side and roll together into one long log. Fold log in half and place side by side, alternating colors. Roll dough to 30 cm (12-inch) log; twist logs several times to marble the dough. Chill at least 30 minutes then slice into approximately 1 cm thick cookies.
And third, using the ice cream or cookie scoop, alternately take pieces of each dough until your scoop is full, press the spoon lightly with your palm, and put the dough ball on the baking sheet.
The first way is pretty good, but when I form balls, I somehow lose that fluffiness in the cookie, because the butter on the touch of my hands starts to melt. In a 2nd way, cookies are thinner and crunchier. The ice cream or cookie scoop is my favorite way. In this way you form a perfect dough ball, the butter does not come into contact with the heat of the hand, and the dough is not over mixed like there are pockets of air remain inside which then give a cookie finely soft, fluffy texture.
