For the cake batter: Separate egg yolks from egg whites and place them in two different bowls.
4 eggs,
Add ⅓ cup of sugar into the bowl with egg whites and beat on high speed until stiff.
⅔ cup sugar
Stop beating the egg whites as soon as they get fluffy and stiff. Do not over-beat them or they will liquefy again.
Add the second half of the sugar into the egg yolks and beat on high speed until fluffy and white yellow.
Place the egg yolk and sugar mixture into the bowl with the beaten egg whites.
Using a rubber spatula, gently fold the egg yolks into egg white mixture.
Now sift in ⅔ cup of flour into the egg and sugar mixture and continue folding until the ingredients are well combined. Try not to over mix; you don't want to let all the air out of the beaten egg whites. The more air stays in, the fluffier your cake will turn out.
⅔ cup flour
Transfer the batter into a greased 8" pan and bake at 355F for 20 minutes. Do not open the oven until 20 minutes are up. Check the cake after 20 minutes and leave it in there for another 5-10 minutes if needed.
Take the cake out of the pan and let it cool down. Cut horizontally in two layers.
While your cake is cooling down prepare the cream.
