# Directions:
01 - Preheat oven to 350°F. Grease and flour three 8-inch round cake pans.
02 - Whisk cake flour, baking powder, and salt together in a bowl. Set aside.
03 - Using an electric mixer, beat butter and sugar until light and fluffy, approximately 3 minutes.
04 - Add egg whites one at a time, mixing thoroughly after each addition; stir in vanilla extract.
05 - Alternately add flour mixture and milk to the butter mixture, beginning and ending with 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 cakes in pans for 10 minutes, then turn onto wire racks to cool completely.
08 - Combine coconut milk and sugar in a small saucepan; bring to a simmer, stirring until sugar dissolves. Remove from heat, stir in shredded coconut, and cool to room temperature until thick but spreadable.
09 - Whisk egg whites, sugar, water, and cream of tartar in a heatproof bowl set over simmering water. Beat on high with a hand mixer until stiff, glossy peaks form (about 7 minutes). Remove from heat, stir in vanilla, and beat 2 minutes more.
10 - Place one cake layer on serving platter. Spread half of the coconut filling evenly on top. Repeat with second layer and remaining filling, then top with third layer.
11 - Frost entire cake with seven-minute frosting. Press shredded coconut onto sides and top for decoration.
12 - Allow cake to set for at least 30 minutes before slicing.
