Preheat oven to 175°C. Lightly spray three 20 cm round cake pans with baking spray, line the bottoms with parchment paper circles, and spray parchment for easy release.

In a stand mixer bowl, add flour, sugar, cocoa powder, baking soda, baking powder, and salt. Mix on low with paddle attachment until well combined.
03 -
In a separate bowl, whisk together buttermilk, vegetable oil, eggs, and vanilla extract until smooth.

Add the wet mixture to the dry ingredients. Mix on low speed until incorporated, then slowly stream in the hot coffee. Continue mixing on low for 2 minutes until batter is even and smooth. Scrape down the bowl as needed.
05 -
Evenly divide the batter among the prepared pans. Bake for 35–40 minutes, or until a skewer inserted in the centre comes out clean. Cool cakes in pans for 10 minutes, then invert onto racks to cool completely.
06 -
In a heavy saucepan, whisk together butter, evaporated milk, sugar, vanilla, and beaten egg yolks. Cook over medium heat, stirring constantly, until mixture thickens and bubbles. Remove from heat and stir in coconut and pecans. Let cool to room temperature.

Once cakes are cool, use a serrated knife to level the tops if needed, ensuring flat, even layers.
08 -
Place one cake layer on a serving plate, spread one third of the coconut-pecan topping evenly. Repeat with the second layer and topping, then finish with the final cake layer and remaining topping.

Refrigerate the assembled cake for at least 1 hour for easier slicing. Bring to room temperature before serving for best texture.
