Line the bottom of your 8 inch round pan with parchment or grease it with butter. Preheat your oven to 180 C / 350 F.
Beat together the eggs and sugar on medium high speed until the mixture triples in volume and becomes light and fluffy . If you lift your whisk /beater and make an "8" on top of the batter , you should be able to see the 8 for a couple of seconds until it disappears into the batter.Add the vanilla and beat a minute.
Sift in the flour and salt. Fold in usually a spatula gently until all the flour is incorporated into the batter. Try not to deflate the batter too much.
Spread batter into prepared tin . Tap against the counter . Bake in the preheated oven at 180 C/ 350 F for 20 - 24 minutes .
When done , the top will be brown and the edges will come away from the sides of the pan. The cake will spring back when touched. Cool in pan for 5 minutes, run a knife along the edge and remove the cake. Cool (right side up ) on a wire rack completely.
To make the evaporated milk : Simmer 1 and half cups whole milk in a thick bottomed sauce pan until it reduces to half cup milk . To make this easier , pour half cup milk into the pan , make a marker or put some tape on the outside of the pan at this level. Pour in the rest of the milk and simmer until the milk comes down to that level. Strain and cool.
When your cake is cool , prepare your soaking syrup by mixing together the condensed milk, cream and the evaporated milk.
Pour about quarter cup of the syrup all over the top of the cake. Wait for it to be absorbed. Pour the remaining in the same way gradually . Rest the cake in the fridge overnight before serving. Top with the whipped cream before serving.
