Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
In a large bowl, whisk together the almond flour, hazelnut flour, baking soda, cinnamon, ground star anise, cloves, allspice, ginger, coriander, nutmeg, and cardamom.
In a separate bowl, beat the eggs and brown sweetener until well combined. Add the keto honey and mix thoroughly.
Gradually add the dry ingredients to the wet ingredients, mixing until a dough forms. Fold in the candied orange lemon rind to evenly distribute throughout the dough.
Cover the dough with plastic wrap and chill in the refrigerator for at least 30 minutes. This will make it easier to handle.
Roll the dough into balls (about 1-2 tablespoons each) and flatten them slightly to form discs. Place them on the prepared baking sheet, leaving about an inch of space between each cookie.
Bake in the preheated oven for 12-15 minutes, or until the edges are golden and the tops are firm to the touch. Avoid overbaking to keep them soft and moist
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
For a traditional touch, drizzle the cookies with a sugar-free glaze or dip them in melted dark chocolate (keto-friendly). Let the glaze or chocolate set before serving.
