This Cream of Coconut Cake is a moist, indulgent sheet cake made with a white cake mix base, soaked in a rich mixture of cream of coconut and sweetened condensed milk, then topped with fluffy Cool Whip and a generous layer of sweetened shredded coconut. The poke-cake technique lets every bite soak up that deeply sweet coconut flavor, creating a texture that is impossibly tender and rich. It is an easy, make-ahead dessert that is perfect for potlucks, parties, and holidays.

3/4cupsweetened shredded coconutAbout 65g; can be toasted for deeper flavor
Instructions
Preheat oven to 350°F (175°C). Generously spray a 9x13-inch baking dish with non-stick cooking spray, coating the bottom and sides.
In a large bowl, combine the white cake mix, egg whites, vegetable oil, and water; beat with an electric mixer on medium speed for 2 minutes until smooth. Fold in 3/4 cup shredded coconut, then pour batter into the prepared baking dish.
Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Begin checking at 25 minutes to avoid overbaking.
While the cake bakes, stir together the cream of coconut and sweetened condensed milk in a small bowl until fully combined. Set aside.
Remove cake from oven and immediately poke holes all over the surface (about 1 inch apart) using a fork or skewer. Slowly pour the coconut soak over the warm cake, pausing to let it absorb as you go.
Transfer the pan to a wire cooling rack and allow the cake to cool to room temperature, about 45 to 60 minutes, before frosting.
Once fully cooled, spread the thawed Cool Whip evenly over the top of the cake using an offset spatula, reaching all the edges.
Sprinkle the remaining 3/4 cup of shredded coconut evenly over the Cool Whip and press gently so it adheres.
Cover and refrigerate for at least 2 to 4 hours, or overnight for best results. Slice and serve cold.
Notes
Use cream of coconut (such as Coco Lopez or Coco Real), not coconut cream or coconut milk — they are not the same product and will not give the correct flavor or sweetness.
Pour the soak over the cake while it is still warm. Warm cake absorbs the liquid faster and more evenly than a cooled cake.
Poke holes generously and close together — the more holes, the more the coconut soak can penetrate every bite.
For a richer cake base, substitute melted butter for the oil and whole milk for the water in the cake mix directions.
To toast the coconut topping, spread shredded coconut on a baking sheet and bake at 325°F for 3 to 5 minutes, stirring once, until lightly golden. Watch carefully as it burns quickly.
Thaw Cool Whip in the refrigerator overnight rather than on the counter for a smoother, more spreadable consistency.
This cake is best made a day ahead. Overnight chilling allows the soak to fully penetrate the crumb and intensifies the coconut flavor.
Store covered in the refrigerator for up to 5 days. This cake should always be served cold and does not hold up well at room temperature for extended periods.
To freeze, wrap individual slices (without the Cool Whip topping) in plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge and add fresh Cool Whip before serving.
For a piña colada variation, fold drained crushed pineapple into the batter and add a tablespoon of coconut rum to the soak.
