Helpful Tips:
1) Do not bake the cake quickly at a high temperature and don't remove hot cake out of a baking pan. otherwise the cake could fall apart and crack on top. Baking cake at a lower temperature will help the cake rise much higher and bake more evenly.
2) Please understand that everyone's oven work differently. You should also check the temperature of your oven. if not, your cake won't rise well. 
3) You can test the cake by poking it with a skewer, if it's cooked the skewer will come out clean. if not pop it back in the oven and bake until it's ready. 
4) Folding egg whites into a cake batter. Do not stir and never use an electric mixer. 
5) Do not over or under-beat the egg whites.
6) Beating egg whites is a very important process, It will help your cakes rise with perfectly.
7) Cover with foil after a few minutes if the cake of top starts to get brown and continue rising nicely with a golden top.
