Preheat the oven to 350 degrees. Lightly spray (or butter & flour) a 9x13-inch pan; set aside.
In a medium mixing bowl, whisk together the cake flour, baking powder, cinnamon, salt, and nutmeg; set aside.
In the bowl of a stand mixer (or a large mixing bowl with a hand mixer) beat the butter on medium speed until pale and fluffy, about 2 minutes. Turn mixing speed to low and add the sugar and vanilla. Scrape down the sides, then add the eggs, mixing after each addition.
With mixing speed on low, gradually add the dry ingredients, mix just until combined. The batter will be thick. Spread the batter into the prepared pan, place in the oven and bake for 20 to 25 minutes, or until the cake is lightly golden brown and springs back when touched. NOTE: It will rise significantly during the baking process. Remove from the oven and allow to cool in the pan for 5 minutes.
Meanwhile, in a large glass measuring cup or a medium bowl, whisk together the evaporated milk, sweetened condensed milk, half and half, and vanilla extract. Poke the top of the cake with a skewer or fork. Slowly pour the glaze over the cake, allowing the liquid to be absorbed before pouring more. When cover with foil and place in the refrigerator and allow the cake to sit for at least 4 hours before serving, preferably overnight.
Remove the cake from the refrigerator. In the bowl of a stand mixer or with a hand mixer, beat the heavy cream, powdered sugar and vanilla extract until stiff peaks form. Spread over the cake, then dust with cinnamon. Garnish with toasted coconut and fresh strawberries, if desired. Serve immediately or return to the refrigerator until ready to serve.
Notes
-You don't have to add the cinnamon or nutmeg to the cake batter, but I think it gives this cake just a touch of added flavor!
