First, measure out and add all of the dry ingredients: flour, spices, and baking soda to a single bowl and whisk them until they are fully mixed together and uniform. Set the dry ingredients aside.
Begin adding the wet ingredients to a stand mixer with a beater attachement. First, whip up the butter until it lightens and increases in volume a touch. Next, add the brown butter and cream the two ingredients together for another 2-3 minutes. (Scrape down the bowl with a spatula for each new ingredient added to ensure proper mixing.)
The date paste gets added next. Mix it in until it becomes uniform and all of the clumps are gone. At this point add in the molassess and honey and whip until the mixture begins to look like frosting. Once the proper texture is reached, add in the egg and mix until it returns to the same texture it was before the egg was added.
Slowly add in the dry ingredients and mix until the dry flour is no longer visible. Do NOT overmix. The dough should be very soft. If you overmix the dough it will toughen. Use a sturdy spatula for a final bowl scrape and hand mix, to make sure all of the ingredients are homogeneous and ready to scoop.
Grab a #50, 1.6in (4cm) cookie scoop and line a 1/2 sheet baking tray with a silicone mat. The scoop should hold roughly 1.3tbsp or 25g of dough and should yield roughly 34 cookies. Scoop cookies onto the tray until all of the dough is gone. Once scooped, roll all of the dough mounds into balls and cover them with your prefered cling wrap. Chill the dough for 24 hours for best results. (See FAQs on chill times)
After resting the dough, preheat your oven to 375°F (190°C). When the oven is at temperature for 15-20 minutes, arrange your cookies roughly 1in (2.5cm) apart and place them in the oven. The cookies don’t spread much. As soon as they are in, turn the temperature down to 350°F (177°C) and bake for 10-12 minutes.
While the cookies are baking make the glaze. Whisk together the powdered sugar and water. It should make a thick glaze that visibly ribbons upon itself and takes 1-2 seconds to reincorporate. Set the glaze aside.
When the cookies are done baking, their tops should be completely puffed and not look wet. The cookies may also crack a bit, that’s okay. Take the cookies out of the oven and let them cool for at least 5 minutes. They should be slightly warm and fully set before coating. Prep for coating by placing down parchment or wax paper underneath a cooling rack near the bowl of glaze. Give the glaze a good mix just before dipping the cookies.
To coat the cookies, place them individually in the bowl of glaze, bottom facing down. Use a fork to scoop glaze over the top of the cookie, until it is fully covered. Then, slide the fork under the cookie and lift it up out of the bowl. Let the glaze drip a bit before placing the cookie onto the cooling rack. The cookies will harden to the cooling rack as they dry. Allow the glaze to set and harden for about an hour before giving them a gentle twist to unstick them a bit. Then, continue drying for another hour or so before storing and/or eating.
