Preheat the oven to 350 degrees. Spray a 9x13 baking dish with nonstick baking spray.
In a mixing bowl, beat the egg whites until stiff peaks form. Set aside.
In another bowl, combine sugar and egg yolks. Beat on high for 2-3 minutes until light yellow. Mix in coconut extract and milk.
Gradually mix in the dry ingredients until just incorporated.
Gently fold in the beaten egg whites until well combined.
Pour the batter into the prepared baking dish and bake for 30-35 minutes or until a toothpick comes out clean. Allow it to cool completely, then poke holes all over the cake with a toothpick.
Allow the cake to cool completely before continuing on with the next steps.
Prepare the topping
Mix evaporated milk, sweetened condensed milk, and lite coconut milk. Pour over the poked cake. Cover and refrigerate for 4 hours.
Before serving, top with whipped cream, coconut flakes, and optionally, strawberries.
