Preheat your oven to 350 degrees Fahrenheit. Grease a 9x13'' baking pan with cooking spray, or line with parchment paper.
In a large bowl, prepare the brownie mix to package instructions. If you use a different brand, you may need different amounts of eggs, water and vegetable oil.
In a small bowl, add gingerbread swirl ingredients: ginger, cinnamon, cloves, vanilla, butter and molasses. Stir well to combine.
Add brownie batter to prepared pan.
Pour gingerbread swirl over the top of the brownie batter and use a knife to gently swirl the gingerbread through the brownie mixture.
Sprinkle the top with sprinkles, then bake for 20-23 minutes, until the center is no longer gooey.
Allow to cool for at least 20 minutes before slicing.
