Preheat oven to 350℉ and prepare a 9x13 baking dish with parchment paper or baking spray.
In a large mixing bowl, whisk together the egg yolks, white sugar and brown sugar until fully combined.
Add the cake flour, baking powder and salt. Gently fold everything together until a smooth batter forms. Set aside.
In a separate mixing bowl, beat the egg whites using a hand mixer on high speed until stiff fluffy peaks form, about 8-10 minutes.
Carefully fold the whipped egg whites into the cake batter a little at a time. Be gentle so the batter stays light and airy.
Pour the batter into the prepared baking dish and spread evenly. Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
While the cake bakes, prepare the milk mixture.
In a medium bowl, whisk together the evaporated milk, sweetened condensed milk, milk and vanilla extract until combined.
Once the cake is done baking, remove it from the oven and use a fork to poke holes all over the top of the cake.
Slowly pour the milk mixture evenly over the cake, allowing the liquid to soak in before adding more.
Let the cake rest for at least 2 hours so it can fully absorb the milk mixture.
During the last 30 minutes of chilling, prepare the whipped topping and slice the strawberries.
In a large bowl, combine the heavy cream, powdered sugar, vanilla extract and salt.
Use a hand mixer to whip until soft peaks form and the topping becomes thick and fluffy.
Spread the whipped topping evenly over the cooled cake.
Sprinkle cinnamon over the top and garnish with sliced strawberries.
Slice, serve and enjoy.
