In a large bowl, combine 1 cup unsalted melted butter with 1/2 cup granulated sugar, and 1/2 cup packed brown sugar using a large whisk.
Then stir in 1 egg + 1 egg yolk, 1/2 teaspoon vanilla extract, and 1/4 cup molasses.
Now place a fine mesh sieve over the bowl and sift in 3 cups all-purpose flour, 2 tsp baking soda, 1 tsp salt, 2 tsp ground ginger, 1 tsp ground cinnamon, 1/4 tsp ground nutmeg, and 1/2 tsp ground cloves.
Then use a spatula to thoroughly combine the wet and dry ingredients.
Roll each dough ball into a ball and coat them in a bowl full of granulated sugar (you’ll need about 1/2 cup). Then place them back on the baking sheet and lightly press them down with your hand or the bottom of a glass cup.
Preheat your oven to 350°F and bake for about 8 minutes.
Once the cookies are cooled, dip half of each cookie into the melted chocolate and place them on a parchment-lined baking sheet. While the chocolate is still wet, sprinkle on a little bit of candied ginger. Let the chocolate set for at least 1 hour before serving.
Notes
Flatten the cookies- To get a crisp cookie, you'll want to flatten it so it cooks faster. Too thick and the center will be cakey.
Don't scorch the chocolate- Stir the chocolate as you warm it so it doesn't scorch. You can do this in a double boiler or in the microwave.
Let the cookies cool before adding toppings- Hot cookies will make it impossible for the chocolate to set and the candied ginger will melt off. So let them cool completely first.
