Choco Coconut Dream Cake 
Ingredients
For the Cake Layer
1 box chocolate cake mix (standard 15.25‑ounce size)
3 large eggs
½ cup vegetable oil
1 cup water
For the Coconut Filling
1 cup sweetened condensed milk
1½ cups sweetened shredded coconut
½ cup powdered sugar
For the Chocolate Ganache Topping
1 cup heavy cream
1½ cups semisweet chocolate chips (about 9 ounces)
1 teaspoon vanilla extract
Optional Garnishes
2 tablespoons additional sweetened shredded coconut
1 tablespoon chocolate shavings or curls
Instructions
Step 1 — Prepare the Oven and Pan
Preheat your oven to 350°F. Lightly grease a 9×13‑inch baking dish with cooking spray or butter. For easier removal later, you can line the dish with parchment paper, leaving a 2‑inch overhang on the two long sides to use as handles.
Step 2 — Make the Cake Batter
In a large mixing bowl, combine the chocolate cake mix, 3 eggs, ½ cup vegetable oil, and 1 cup water. Use an electric mixer on medium speed for about 2 minutes, scraping down the sides of the bowl once halfway through. The batter should be smooth and fully blended with no dry pockets.
Step 3 — Bake the Cake
Pour the batter into the prepared dish and spread it evenly with a spatula. Bake for 25 to 30 minutes. To check for doneness, insert a toothpick into the center of the cake. It should come out clean or with just a few moist crumbs attached — not wet batter. Do not overbake, or the cake will become dry.
Step 4 — Make the Coconut Filling While the Cake Bakes
In a medium bowl, combine the sweetened condensed milk, 1½ cups shredded coconut, and ½ cup powdered sugar. Stir with a spoon or rubber spatula until fully mixed. The mixture will be very thick and sticky — similar to soft cookie dough. This is correct.
Step 5 — Add the Coconut Layer to the Warm Cake
Remove the baked cake from the oven and place the pan on a cooling rack. Let the cake cool for exactly 10 minutes. It should still be warm but not piping hot. Using a spatula or the back of a spoon, carefully spread the coconut filling evenly over the top of the cake, reaching all the way to the edges of the pan.
Step 6 — Prepare the Chocolate Ganache
Pour the heavy cream into a small saucepan. Place it over medium heat. Watch the cream closely; as soon as tiny bubbles appear around the edge of the pan (do not let it come to a full boil), remove the pan from the heat immediately.
Place the chocolate chips in a separate heatproof bowl. Pour the hot cream directly over the chips. Let the bowl sit untouched for 1 to 2 minutes — this allows the heat to melt the chocolate gently. Then stir slowly with a whisk or spoon until the mixture becomes smooth and glossy. Stir in the vanilla extract.
Step 7 — Assemble the Ganache Topping
While the ganache is still warm and pourable, slowly pour it over the coconut layer. Use an offset spatula or the back of a spoon to spread it evenly across the entire surface, working quickly before the ganache begins to set. If desired, sprinkle the additional shredded coconut and chocolate shavings on top for decoration.
Step 8 — Chill the Cake
Place the uncovered cake in the refrigerator. Chill for at least 1 hour to allow the ganache to set fully and the layers to firm up. For best results, chill for 3 hours or overnight. This resting time also makes the cake much easier to cut into clean squares.
Step 9 — Slice and Serve
Remove the cake from the refrigerator. Slice into 12 even squares (3 rows by 4 rows). You can serve the cake chilled directly from the fridge, or let slices sit at room temperature for 10 to 15 minutes for a softer texture. Store any leftovers covered in the refrigerator for up to 5 days.
