Slice off the top
If the cake is dome-shaped, you need to slice off the top with the help of a serrated knife, which should help you make the surface flat and uniform for the kind of frosting you are looking for.
In order to keep your cake moving while you frost, add a little amount of frosting to the centre of the platter.
Add the wax paper
You can hold the cake in place by lining the edges of the platter with the help of wax paper strips. You can now set the cake on the platter.
Frost the top
Before you frost the sides, you need to frost the top. A table knife or an offset spatula should be used to spread the frosting evenly on the cake. If you wish to have more than one layer of frosting then repeat the same step.
Frosting often gets runny, especially if the temperature in the kitchen is hot. In such a scenario, you need to put the cake in the freezer for a few minutes before you continue frosting.
By using a spoon, you can add finishing touches to the cake. Keeping the surface of the cake smooth or creating waves is completely your choice. In order to keep the layers from sliding, insert the wooden skewer through the middle of the cake, especially if the cake is tall and layered.
Remove the wax paper
You can now remove the wax paper and enjoy the wonderful and professional look of the frosting on your cake.
