Preheat your oven to 350°F (175°C). Get a 9-inch round cake pan ready by greasing it and placing parchment paper at the bottom. In a large bowl, mix together the flour, sugar, cocoa powder, salt, baking powder, and baking soda. Next, stir in the oil, buttermilk, vanilla, and eggs until smooth. Finally, slowly pour in the coffee or warm water while gently mixing. Don’t worry if the mixture seems a little runny—this is normal.

Pour the batter carefully into the prepared pan. Bake for around 30 to 35 minutes, then test it with a toothpick—if it comes out clean, you're good! Let it cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.

Heat the cream in a small saucepan on medium until it's close to boiling. Take it off the heat and pour it over the chopped chocolate in a bowl. Let it sit for a minute or two, then stir until velvety smooth. Mix in the butter, and let the ganache thicken just enough to be easy to pour.

Microwave the dark chocolate in small intervals, stirring in between to ensure it doesn’t burn. Pour the melted chocolate into a piping bag or snip the end of a plastic bag to make a small opening. On a parchment-lined tray, pipe out a nest design in random overlapping shapes. Chill it in the fridge for 15 to 20 minutes until it firms up.

Place the cooled cake on a serving plate. Pour the ganache gently over the top, letting it cascade down the sides. Carefully remove your chocolate nest from the parchment and place it on top. Fill the nest with your candies or eggs, and it’s ready to serve!
