Prepare your dry ingredients by whisking together the flour and baking soda in a large bowl. If you don’t have a whisk, just use a fork. Set aside.
Make your spice mix. Add the cinnamon, ginger, cardamom, nutmeg, cloves, and allspice in a small bowl or cup and stir. Set aside.
Cut the butter into tablespoon size pieces. It does not have to be perfect.
Add the molasses, honey, brown sugar and butter to a small saucepan.
Heat the mixture over medium-high heat, stirring regularly with a heat resistant rubber spatula or wooden spoon. Do not boil.
Cook until the sugar is dissolved and the butter is melted.
Remove from the heat and pour the mixture into a large heat resistant bowl.
Stir the spice mix into the molasses and honey mixture using the spatula or wooden spoon.
Let the mixture cool down until it is only slightly warm to the touch, about 20 minutes.
When the mixture is cool, stir in the dry ingredients. Be sure all of the flour is incorporated by stirring up from the bottom and scraping the sides.
Place a piece of plastic wrap on your work surface.
Lay the dough on the plastic wrap and fold it up, covering the dough entirely.
Let the dough rest in the fridge for at least an hour to overnight.
About 15 minutes before you are going to use the dough, preheat the oven to 350 degrees F.
Line two baking sheets with silicone mats or parchment paper.
Form the pfeffernusse by scooping about a tablespoon of dough for each cookie and rolling it between your hands.
Place the formed cookies on the prepared tray, leaving about 1 inch between each. They will flatten slightly as they cool.
Bake the cookies until they are lightly browned on the bottom, about 12-14 minutes. If you use two trays, rotate them midway through the bake.
Remove the baked cookies to a wire rack to cool.
Set aside one of the baking sheets with the mat or parchment paper to use when dipping the cookies.
Let the cookies cool completely before dipping them in glaze.
Mix 2 cups of confectioners sugar with 3 tbsp of hot water. You can add a bit more water if you want a thinner glazer or a bit more sugar for a thicker glaze.
Stir in 2 tsp of lemon juice.
Place the wire rack over the prepared baking sheet you used earlier.
Hold a cookie by the edges and dip the top into the glaze. Let the excess run back into the bowl.
Place the cookie on the wire rack and let the glaze harden.
