Instructions
- Preheat and Prepare
Preheat the oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper. - Make the Cake Batter

Add buttermilk, oil, eggs, and vanilla; mix until smooth.
Slowly pour in the hot water and stir until the batter becomes thin and fully combined. - Bake the Cake
Divide batter evenly between pans.
Bake for 28–32 minutes or until a toothpick inserted into the center comes out clean.
Let cakes cool completely before assembling. - Prepare the Coconut Filling
In a bowl, mix coconut, condensed milk, and vanilla until fully combined.
Set aside. - Make the Ganache
Heat heavy cream in a small saucepan until steaming.
Pour over chocolate chips and let sit for 2–3 minutes.
Stir until smooth and glossy. Allow to thicken slightly before using. - Assemble the Cake
Place the first cake layer on a serving plate.
Spread the coconut mixture evenly on top.
Add the second cake layer.
Pour ganache over the cake, letting it drip naturally along the sides.

Serving Suggestions

Discussion Questions
- Do you prefer the filling sweeter, or would you try using unsweetened coconut for contrast?
- Would you add almonds to transform this into an Almond Joy–style cake?
- Which topping do you think enhances the cake best—berries, toasted coconut, or extra chocolate drizzle?
Notes
- Use room-temperature ingredients to ensure even mixing.
- If the ganache becomes too thick, gently warm it for a few seconds.
- Cakes made with cocoa powder often taste richer the next day—this one is no exception.
- Hot water is essential for blooming the cocoa and deepening the chocolate flavor.
