Beat the soft 1 cup unsalted butter with ¾ cup light brown sugar for 2 minutes, until light and fluffy. Use a large bowl and an electric mixer or the stand mixer with the paddle attachment.
Add 2 tablespoons honey and beat until completely incorporated.
In a medium bowl, stir together 1 cup all-purpose flour, 2 cups whole wheat flour, 1 teaspoon baking soda, ¼ teaspoon salt and ½ teaspoon ground cinnamon.
Add the dry ingredients to the butter mixture in 2 parts and mix on the lowest speed or with a spatula. Barely incorporate the first part and add the second. We don't want to overmix the dough after adding the flour, but it's easier to integrate if we add it in two parts.
Wrap the dough and refrigerate for 30 minutes or until cold and firm enough to roll.
Divide the dough into two pieces and work with one at a time, keeping the other one wrapped in the refrigerator.
Place the dough between two large sheets of parchment paper that fit in the baking sheet you'll be using. With a lightly floured rolling pin, roll the dough to ⅛ - ¼ inch thickness. Try to make it as much of a rectangle or square as possible. With a large kitchen knife or pizza wheel, cut the uneven edges and remove the scraps.
Cut rectangles but don't separate them. Pick with the flat end of a brochette stick to create three dotted lines with four dots each. Transfer to the baking sheet and refrigerate for 15 minutes.
Preheat the oven to 350°F (180°C) while the dough is in the fridge.
Bake directly from the fridge for 12 to 15 minutes, until lightly colored and dry on top. Let cool for 5 minutes and use the knife or pizza wheel to cut over the lines again. The cookies will separate. Cool them completely on a wire rack.
Store in airtight tins or cookie jars, as they soften pretty quickly at room temperature. If this happens, refrigerate them.
