3 cups cake flour (not self-rising)
2 teaspoons baking powder
1 teaspoon salt
3 sticks (1 1/2 cups) unsalted butter, room temperature
2 1/4 cups sugar
1/2 teaspoon pure vanilla extract
1 cup coconut milk
8 large egg whites
1 1/4 cups shredded sweetened coconut
Seven-Minute Frosting (below)
Fresh Roasted Coconut, for garnish
Preheat oven to 350°. Line two standard 12-cup muffin pans with paper liners; set aside.
In a medium bowl, whisk together flour, baking powder, and salt; set aside.
In the bowl of an electric mixer fitted with the paddle attachment, beat butter and 2 cups sugar until light and fluffy, 3 to 4 minutes, scraping down sides of the bowl as needed. Beat in vanilla. With mixer on low speed, add flour mixture in three parts, alternating with the milk and beginning and ending with the flour; beat until just combined. Transfer mixture to a large bowl; set aside.
In the clean bowl of an electric mixer fitted with the whisk attachment, beat egg whites on low speed until foamy.
With mixer running, gradually add remaining 1/4 cup sugar; beat on high speed until stiff, glossy peaks form, about 4 minutes. Do not overbeat. Gently fold a third of the egg-white mixture into the butter-flour mixture until combined. Gently fold in remaining egg-white mixture; stir in shredded coconut.
Divide batter evenly among the muffin cups, filling each with a heaping 1/4 cup batter.
Bake, rotating pans halfway through, until the cupcakes are golden brown and a cake tester inserted in the center of a cupcake comes out clean, 20 to 25 minutes. Transfer pans to a wire rack.
Invert cupcakes onto rack; then reinvert and let cool completely, top sides up. Frost cupcakes with seven minute frosting, swirling to cover. Cupcakes may be stored in a covered container in the refrigerator for up to 3 days. Garnish with fresh coconut just before serving.

Seven-Minute Frosting
3/4 cup plus 2 tablespoons sugar
1 tablespoon light corn syrup
3 large egg whites, room temperature
In a small, heavy saucepan, combine 3/4 cup sugar, corn syrup, and 2 tablespoons water. Heat over medium heat, stirring occasionally, until sugar has dissolved. Rub a bit between your fingers to make sure there is no graininess. Raise heat to bring to a boil.
Do not stir anymore. Boil, washing down sides of pan with a pastry brush dipped in cold water from time to time to prevent the sugar from crystallizing, until a candy thermometer registers 230° about 5 minutes. (Depending on the humidity, this can take anywhere from 4 to 10 minutes.)
Meanwhile, in the bowl of an electric mixer fitted with the whisk attachment, whisk egg whites on medium speed until soft peaks form, about 2 1/2 minutes.
Gradually add remaining 2 tablespoons sugar. Remove the syrup from the heat when the temperature reaches 230° (it will keep rising as pan is removed from heat). Pour the syrup in a steady stream down the side of the bowl (to avoid splattering) containing the egg-white mixture, with the mixer on medium-low speed.
Beat frosting on medium speed until cool, 5 to 10 minutes. The frosting should be thick and shiny. Use immediately.
