Based on the recipes from Green Kitchen Stories and The Boy Who Bakes.

Step 1

Combine the flours, baking powder, and salt.

Step 2

Mix the butter, tahini, sugar, and dates (if desired) in a food processor until light and fluffy.

Step 3

Add the eggs (in the food processor).

Step 4

Mix the wet into the dry, add the chocolate.

Step 5

Refrigerate until firm (~2 hours).

Step 6

Preheat oven to 190°C / 380°F, or a bit cooler (170°C) with the fan. (Yes, this is a bit hotter than normal for cookies.)

Roll dough into balls, and coat them with sesame seeds.

Bake for 10-11 minutes.

After they’ve been in the oven for 6-7 minutes, remove the tray from the oven and smack it against the countertop a few times to help the cookies flatten out a bit.

Bake until slightly browned.
