Preheat the oven to 350 degrees F. Grease a 9x13-inch baking dish with nonstick cooking spray. Set aside.
In a large mixing bowl, add the 15.25 ounce yellow cake mix, 3 large eggs, 1 cup water, and ½ cup vegetable oil. Mix using a hand mixer on medium speed until combined.
Add in the 2 teaspoons ground cinnamon, 1 teaspoon ground nutmeg, ½ teaspoon ground ginger, ½ teaspoon ground cardamom, and ¼ teaspoon ground cloves. Mix so the spices are evenly distributed in the batter.
Pour the batter into the prepared baking dish and spread out evenly.
Place in the preheated oven and bake for 25-28 minutes or until a toothpick inserted in the center of the cake comes out clean or with moist crumbs.
Allow the cake to cool off completely before frosting.
Frosting
In a large bowl, add the ½ cup salted butter and 1 cup light brown sugar. Beat with a hand mixer on medium speed until creamed, about 1 to 2 minutes.
Add 1 ½ cups powdered sugar in 1/2 cup increments and mix on low until all of the powdered sugar is worked into the frosting.
Add the 1 tablespoon milk or heavy cream and 1 teaspoon vanilla extract. Beat until combined. If your frosting is too thick, add an additional 1/2 tablespoon of milk at a time and mix in until the desired consistency is reached.
Once the cake is completely cooled, spread the frosting evenly on top using an offset spatula.
Topping
In a small bowl, add the 2 tablespoons granulated sugar and 1 teaspoon ground cinnamon. Stir until combined. Set aside.
Sprinkle the cinnamon sugar on top.
