Pre heat oven to 350F and parchment line the bottom of a loaf pan and rub it with butter or non-stick spray. Separate egg yolks and egg whites in two separate bowls.
Meringue – In a bowl fitted to a stand mixer with whisk attachment or if you have handheld mixer, beat egg whites on medium speed until they begin to look foamy and thicken up. They will change the texture to white fluffy shiny finish, add sugar, vanilla extract and speed up the mixer and whip until stiff peaks form and it looks glossy. Remove meringue in a clean bowl. Set it aside.
Cake – in the same bowl, beat butter with sugar until light and fluffy, add yolks and vanilla extract and beat until they well combined. Add lemon zest, milk and baking powder and flour and mix until it is well combined.
Add this cake batter on the prepared loaf pan, spread out evenly. Dollop the meringue mixture on top and spread it evenly covering the cake batter. Bake cake for 20-25 minutes, or until a toothpick inserted comes out clean.
Once done, let the cake cold in pan for few minutes and then remove it with parchment paper on a cooling rack to cool it completely.
In a bowl, combine strawberries with 1 tbsp sugar and lemon juice and let it macerate until ready to add them to cake. You can do this step while cake is baking or cooling.
In a bowl, combine heavy whipping cream and crème fraiche, 1 tbsp sugar and vanilla extract and whip until soft peaks form.
Assembly - When ready to serve, transfer cake to a platter; dollop whipped cream and spread it with offset spatula all over the cake. Add macerated strawberries with the juices. I also added some silvered pistachios.
