In a large bowl, sift the flour and mix with the baking soda and cornstarch. Booking.
In another bowl or with a mixer, beat the butter, white sugar and brown sugar until the mixture is smooth and creamy.
Add the vanilla essence and eggs one at a time, beating well after each addition. Little by little, add the flour, cornstarch and baking soda mixture to the bowl with the wet ingredients. Mix until all ingredients are well combined. Not about robes.
Chop the black garlic.
Add the chocolate chips and garlic and stir to distribute them evenly in the dough.
On a pre-greased or parchment-lined baking sheet, place tablespoons of dough with enough space between them so the cookies have room to expand as they bake.
Place the tray in the refrigerator and let the dough balls rest for at least 30 minutes or overnight.
Bake in the preheated oven at 180-200 degrees for about 10-12 minutes, or until the edges of the cookies are golden, but the center is still a little soft. Cooking time may vary depending on the size of the cookies and the actual temperature of your oven, so don't neglect your cookies and check them constantly.
Once the cookies are ready, remove them from the oven and let them cool on the tray for a few minutes before transferring them to a cooling rack to cool completely.
