                Preheat oven to 350°F / 180°C and prepare 3 unlined 6 inch / 15 cm aluminum cake pans.
              
              
              
                02 - 
                In a bowl, mix together the dry ingredients (cake flour, salt, and baking powder), sift at least twice, and set aside.
              
              
              
                03 - 
                In another bowl, whisk together the egg yolks with the vegetable oil, 3/4 of the sugar, vanilla extract, and milk.
              
              
              
                04 - 
                Add the dry ingredients to the wet ingredients and whisk until smooth.
              
              
              
                05 - 
                Place the egg whites in the bowl of a mixer and beat on medium-slow speed for 2-3 minutes until bubbles appear. Add the cream of tartar and remaining sugar, then beat on high speed for 3-4 minutes until the meringue is firm and stiff.
              
              
              
                06 - 
                Add a small amount of meringue to the batter and mix quickly to loosen. Gently fold in the rest of the meringue with a spatula in circular motions until smooth.
              
              
              
                07 - 
                Pour the batter into the 3 pans and use a knife to remove air pockets. Bake on the middle rack for 30-40 minutes until golden brown and a toothpick comes out clean. Let cakes cool upside down for at least 1.5 hours.
              
              
              
                08 - 
                Place sliced strawberries with granulated sugar in a bowl. Refrigerate and remove excess juice before assembling.
              
              
              
                09 - 
                Place cold heavy cream, powdered sugar, and vanilla extract in a large bowl. Beat on medium speed for 3-4 minutes until thick and stiff. Add cornstarch or cream of tartar for stability if desired.
              
              
              
                10 - 
                Place the first cake layer on a cake board. Add whipped cream, create a hollow center for the strawberry filling, and cover with whipped cream. Repeat with the second layer and finish with the last layer.
              
              
              
                11 - 
                Cover the entire cake with whipped cream, smooth it, and decorate the top with fresh strawberries and remaining whipped cream using a piping bag.
              
              
              
                12 - 
                Refrigerate the cake for about 1 hour before serving with strawberry sauce.
