How to Make Matcha and white chocolate chip diamant cookies



  • Cut the butter into 1cm cubes and chill well in the refrigerator.



1.Mix the ingredients listed under "a" and sift them.


2.In a food processor, combine the sifted mixture from step 1 with almond powder, sugar, and salt. Blend until mixed, then add the butter and continue to blend until the mixture resembles coarse meal.

3.Quickly blend in the egg yolk. Be swift to prevent the butter from melting.
4.Transfer the mixture to a bowl and mix in the white chocolate chips.
5.Divide the dough in two, shape each half into a log on a piece of plastic wrap, and let it rest in the refrigerator for about 90 minutes.
6.Remove the wrap from the rested dough, knead lightly, and roll each log into a cylinder about 3cm in diameter and 30cm in length. Wrap each log individually in plastic wrap and freeze for about 30 minutes to firm up.
7.Unwrap the dough and lightly brush with water to make the granulated sugar adhere more easily.
8.Coat each log with 2-3 tablespoons of granulated sugar, ensuring it's evenly covered.
9.Cut the logs into 1cm thick slices, place them on a baking sheet lined with parchment paper, and bake in an oven preheated to 170°C (338°F) for 15-18 minutes.
