Preheat your oven to 180 C (350 F), grease with butter a 9x13 baking pan or bundt pan.
Add all the Cake ingredients to a mixing bowl.
Mix together until just combined.
Pour the cake mix in the baking pan and spread out evenly.
Bake a 9x13 pan 30-35 minutes or a bundt cake 35-45 minutes. The cake should be golden brown and a toothpick inserted in the center comes out clean. Remove to a rack to cool completely.
If using a bundt pan, after the pan has set on a rack for 10 minutes, place a plate on the top, grab each side with oven pads, both the pan and plate, and turn the pan and plate over to turn the cake out onto a plate. Let the cake completely cool.
Prepare the icing when the cake is completely cooled. In a mixing bowl, stir together the first 4 ingredients, then use an electric mixer to mix in the powdered sugar.
Drizzle the icing over the cake. (I also sprinkled some candy sprinkles on it.)
Slice, serve, and enjoy.
