You will need two 6-inch round baking pan or 1lb loaf tin. Line with the prepared round of parchment paper in the bottom and the sides and grease with butter.

Method:
1) In a saucepan, heat the butter over low heat, add milk and sugar, stir until melted. Turn off the heat, add the egg yolks one at a time and and beat for 5 seconds, add a pinch of sea salt and sift in the cake flour and whisk until smooth. 

2) In a separate bowl, whisk (B) egg whites until foamy then add cream of tartar and sugar a little bit at a time until to a thick and stiff peak stage, about 3 minutes.

3) Strain the batter for extra smooth, and folding the egg whites into a smooth batter, and mix until incorporated.

4) Pour the mixture into the two, 6-inch prepared tin with baking parchment and use a spatula and smooth the surface.

5) Use a large baking pan for a hot water bath, Bake in the preheated oven 130°C for 40-45 minutes.  rest in the oven for at least 15 minutes until the oven temperature reaches 50°C , and remove from the oven.

6) Once the cake is cool, remove the lining. Transfer the cake to a plate for serving. Any leftover cake can be covered and kept in the fridge for 2 days.

Helpful Tips:
1) I used cold eggs in most of my cake recipes.
2) Place egg whites in a clean, dry bowl, completely free from any grease, oil or water. Beating egg whites is a very important process, It will help your cakes rise with perfectly. Do not under or over beat the egg whites. As soon as the white have reached to stiff peak stage and fold them into your batter and bake immediately.
3) Fold the egg whites into the batter.  cut a path down and don't stir and never use an electric mixer for this. 
4) 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 deflated, shrinks or crack on top.
5) 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.
6) Do you have a favorite brand of butter? Yes, Kerrygold Salted Butter and Tesco British Butter.
