Candied Ginger Lebkuchen

In a medium bowl, whisk together the all-purpose flour, almond flour, ground ginger, salt, baking soda, cinnamon, allspice, cloves and nutmeg. In the bowl of a stand mixer fitted with the paddle, combine the brown sugar, butter and molasses, and beat on medium speed until light and fluffy, about 3 minutes. Add the sour cream and beat until smooth. Add the dry ingredients and minced crystallized ginger, and beat on low speed just until combined.
