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 vanilla cake mix, eggs, water, and olive oil. Mix using a hand mixer on medium speed until combined.
Add in the cinnamon, nutmeg, ginger, cardamom, and 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 butter and light brown sugar. Beat with a hand mixer on medium speed until creamed, about 1 to 2 minutes.
Add powdered sugar in 1/2 cup increments and mix on low until all of the powdered sugar is worked into the frosting.
Add the milk and 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 granulated sugar and cinnamon. Stir until combined. Set aside.
Sprinkle the cinnamon sugar on top.
Serve and Enjoy!
