Pour the batter onto the baking sheet and level the batter.

Bake for 20 minutes or until a toothpick inserted into the middle comes out clean. Once baked, remove the cake from the pan and set on a cooling rack. Place in the freezer for about 15 - 20 minutes to cool completely before frosting.

Meanwhile, make the frosting by adding the butter into a large mixing bowl. Beat the butter on medium speed for 1 minute until smooth and fluffy.
