Notes
Follow this recipe step-by-step to avoid making a huge mistake in baking this cake. Make sure that you are using room temperature ingredients to combine them easily.
Don't, under any temptation, try to open the oven for a peek to see what has become of your cake batter. Opening the oven while baking is not yet complete will allow heat to escape, which will alter the temperature inside the oven and will cause the cake to sink or collapse.
Dust the springform pan with flour or butter from the sides to the bottom before filling it with baking paper to make sure that the cake will not stick.
