how to make a cake
first make sure you don't put enough flour in the pan. The cake should stick to the bottom nicely. Pry cake loose with an icing knife and then run the knife along the perimeter of the cake so that you cut the bottom edge at a 45 degree angle. Place cakes on a decorative cake stand. Wedge missing pieces between layers.
Apply frosting generously.
Add sprinkes. Half the container will do nicely.
If you use icing from the previous year, you will need to apply much pressure when squeezing. Make sure you don't center the number, as symmetry is so last year. Add candles.
