Method
-
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter, or line it with parchment paper for easier removal.
-
In a large mixing bowl, combine chocolate cake mix, eggs, oil, and water. Mix according to package directions (about 2 minutes) until smooth and well combined.
-
Pour batter into prepared dish and bake for 25–30 minutes or until a toothpick inserted into the center comes out clean. Do not overbake.
-
While the cake bakes, prepare the coconut filling. In a medium bowl, combine condensed milk, shredded coconut, and powdered sugar. Stir until thick and fully combined.
-
When cake is done, let it cool for 10 minutes, then spread the coconut filling evenly over the warm cake to allow it to slightly melt into the top.
-
To make ganache, heat heavy cream in a saucepan over medium heat until just simmering. Pour over chocolate chips and let sit for 1–2 minutes, then whisk until smooth and glossy. Stir in vanilla extract.
-
Pour warm ganache over the coconut layer, spreading evenly with an offset spatula. Top with extra shredded coconut or chocolate curls if desired.
-
Refrigerate for at least 1 hour or until ganache is set. Slice into squares and serve chilled or at room temperature.
Notes
Use high-quality chocolate chips for the ganache and toast the shredded coconut for extra flavor and texture. Store covered in the refrigerator for up to 5 days. Serve chilled or at room temperature for a fudgier texture.
