# How-To Steps:
01 - Preheat the oven to 350°F. Grease and flour three 8-inch round cake pans.
02 - In a bowl, whisk together the cake flour, baking powder, and salt. Set aside.
03 - Using an electric mixer, beat the butter and sugar until light and fluffy, approximately 3 minutes.
04 - Add the egg whites one at a time to the butter mixture, beating well after each addition. Stir in the vanilla extract.
05 - Alternate adding the flour mixture and milk to the butter mixture, beginning and ending with the flour. Mix until just combined.
06 - Divide batter evenly among prepared pans. Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
07 - Cool the cakes in the pans for 10 minutes, then transfer to wire racks to cool completely.
08 - In a small saucepan, combine coconut milk and sugar. Bring to a simmer while stirring until sugar dissolves. Remove from heat, stir in shredded coconut, and allow to cool to room temperature until thick but spreadable.
09 - In a heatproof bowl set above simmering water, whisk egg whites, sugar, water, and cream of tartar. Beat vigorously with a hand mixer until stiff peaks form and mixture is glossy, approximately 7 minutes. Remove from heat, add vanilla, and beat for 2 additional minutes.
10 - Place one cake layer on a serving plate. Spread half the coconut filling on top. Add the second layer and spread with remaining filling. Top with the third layer.
11 - Frost the entire cake with the seven-minute frosting. Press shredded coconut onto the sides and top to decorate.
12 - Allow the cake to set for at least 30 minutes before slicing.
