Preheat the oven to 350 degrees F.
Butter a rimmed 18x13-inch baking sheet and dush with the extra flour, shaking out the excess.
In a mixing bowl, whisk the remaining flour, the cornstarch, the baking powder, the baking soda, and the salt together for 20 seconds.
In the bowl of an electric stand mixer fitted with the paddle attachment, whisk the butter and the sugar together until the mixture is very pale and fluffy.
Mix the eggs into the butter mixture, one at a time.
In a medium bowl, whisk the coconut milk, the sour cream, 1 teaspoon of the coconut extract, and the vanilla extract until blended.
Add 1/3 of the flour mixture to the butter mixture and mix on low speed until just combined.
Add 1/2 of the coconut mixture to the batter and mix until combined.
Repeat adding the flour mixture and the coconut mixture to the batter mixture once more and end with the remaining flour mixture, mixing until just combined.
Scrape down the sides and the bottom of the bowl with a spatula.
Fold the batter mixture several times with the spatula to ensure everything is combined.
Pour the batter onto the prepared baking sheet and spread it out into an even layer.
Bake the cake until a toothpick inserted into the center comes out clean, about 23-28 minutes.
Let the cake cool completely on a wire rack.
While the cake is cooling, in the bowl of an electric stand mixer fitted with the paddle attachment, cream the remaining butter until it is smooth.
Add the cream cheese to the butter and mix until it is smooth.
Mix the remaining coconut extract and the powdered sugar into the butter mixture and whip until it is light and fluffy, about 1-2 minutes.
Spread the frosting over the cooled cake and top with the shredded coconut and the raspberries.
Slice and serve, storing any leftovers in the refrigerator in an airtight container.
