Preheat oven to 350°
Add the brown sugar, butter, molasses, and egg to a mixing bowl and beat on medium speed for 2 minutes.
In a separate bowl, combine the flour, baking soda, cinnamon, ginger, cloves, salt, and allspice.
Pour the dry ingredients into the wet ingredients and mix until fully incorporated.
Using a small cookie scoop or a melon baller, scoop cookies on the parchment paper-covered cookie sheet.
Sprinkle each cookie with a bit of white sugar.
Bake for 10-12 minutes until they just start to turn golden brown. Do not overcook the cookie; you want them a little bit chewy.
Let cookies cool completely before adding the filling.
