Step 1: Preheat your oven to 360°F (180°C) with the fan option off, or to 320°F (160°C) if using the fan option. Place your oven tray on the middle shelf, ensuring it’s ready for the cookies.
Step 2: In a large bowl, whisk together the all-purpose flour, sugar, almond flour, cocoa powder, cinnamon, and baking powder. Mix well until all the dry ingredients are fully incorporated, creating a uniform dry mixture.
Step 3: Next, add the honey, orange zest, and orange juice to the dry ingredients. Mix to combine, allowing the flavors to meld.
Step 4: Pour in the lukewarm water gradually while mixing with your hands. Knead until you have an even and elastic dough. If the dough feels too dry, add an additional tablespoon of water at a time until it reaches the desired consistency — compact, elastic, and no longer sticky.
Step 5: Once your dough is ready, roll it out between two sheets of parchment paper to about half an inch thick. This thickness is crucial for achieving the perfect texture.
Step 6: Using a diamond-shaped cookie cutter, cut out the cookies and carefully transfer them to a baking tray lined with parchment paper.
Step 7: Bake the cookies in the preheated oven for 15 minutes. The cookies should be firm to the touch but not overly hard. Once baked, remove them from the oven and let them cool on the tray for a few minutes.
Step 8: After they have cooled slightly, transfer the cookies to a cooling rack. Place a baking tray beneath the cooling rack to catch any chocolate drips later on.
Step 9: When the cookies are fully cooled, melt the dark chocolate in a double boiler over simmering water or in the microwave, stirring until smooth. Allow the melted chocolate to cool slightly.
Step 10: Using a knife, drizzle the melted chocolate over each cookie, ensuring one side is completely covered. Let them sit until the chocolate hardens completely before serving.
