01 - Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, fine salt, ground ginger, ground cinnamon, and ground cloves.
03 - In a separate bowl, stir together the melted unsalted butter, packed brown sugar, molasses, and the large egg until well combined. Gradually fold this wet mixture into the dry ingredients until just incorporated, forming a cohesive dough.
04 - Spread the dough evenly into the prepared baking pan. Bake for 22 to 26 minutes, or until the center is set. Allow the bars to cool completely in the pan.
05 - While the bars cool, melt the white chocolate chips with the neutral oil until smooth. Once the bars are completely cooled, drizzle the melted white chocolate decoratively over the top and allow it to set firm.
