Preheat the oven to 350°F and line a 9 x 9 pan with parchment paper.
Combine the melted butter, brown sugar, and molasses in a large mixing bowl and whisk until homogenous.
Add the egg, vanilla, and fresh ginger (if using), and mix to combine.
In a separate bowl sift together the flour, ginger, cinnamon, cloves, baking powder, and salt.
Add the dry ingredients to the wet ingredients and fold to combine. Do NOT over mix.
In a separate bowl, make the cinnamon sugar. Combine the white sugar, cinnamon and a pinch of salt and mix together.
Transfer the blondie batter into the prepared pan and spread into an even layer. Sprinkle the cinnamon sugar over the blondies, patting it down slightly so that it covers the blondies all the way to the edge.
Bake at 350°F for 20 to 30 minutes or until the edges are set, but the middle is still slightly gooey.
Once the blondies are cool, drizzle with melted white chocolate. Allow the white chocolate to set for 30 minutes before slicing. Enjoy with a glass of milk!
