Nonstick Cooking Spray or Vegetable Oil instructions

*For the Cakes: *
Heat the oven to 350 degrees F
. Adjust the oven rack to the lower-middle position.
Spray the molds with cooking spray
1/2 cup Cake Flour
1/4 cup All-Purpose Flour
1 teaspoon Baking Powder
1/2 teaspoon Salt
2 tablespoonMilk
4 tablespoon
Unsalted Butter
1 teaspoon Vanilla Extract
instructions
In a mixing bowl, whisk together the cake flour, all-purpose flour, baking powder and salt.
In a small saucepan over low heat, heat the milk and butter until the butter melts. Remove from the heat and add the vanilla. Cover to keep warm.
5 large Egg Whites
6 tablespoons Granulated Sugar
1/3 teaspoon Cream of Tartar
instructions
In the bowl of a stand mixer, beat the egg whites on high speed until foamy.
Gradually add 6 tablespoons of the sugar and the cream of tartar and continue to beat until the whites reach soft peaks, about 6 minutes.
5 large Egg Yolks 6 tablespoons Granulated Sugar
Instructions
Transfer the beaten egg whites to a large bowl and add the egg yolks to the standing mixer bowl (there’s no need to clean the bowl).
Beat the egg yolks with the remaining 6 tablespoons sugar on medium-high speed until the mixture is very thick and a pale lemon color, about 5 minutes
. Add the beaten egg whites to the yolks, but do not mix. Sprinkle the flour mixture over the egg whites and then mix everything on low speed for just 10 seconds.
Remove the bowl from the mixer, make a well in one side of the batter, and pour the melted butter mixture into the well. Fold gently with a large rubber spatula until the batter shows no trace of flour and the whites and yolks are evenly mixed, about 8 strokes
Immediately scrape the batter into the prepared molds, filling each with about 3/4 cup of batter (a measuring cup can aid in this process).
Bake until the cake tops are light brown and feel firm and spring back when touched, 13 to 15 minutes.  Mine took long in foil molds. I jeep checking after 15 min every three min until Brown and could poke toothpick
Transfer the pan containing the molds to a wire rack and allow the cakes to cool in the molds.
