Instructions

Preparing the Cake

1. Prepare the Butter: Melt the butter in a medium mixing bowl using a microwave. Set it aside to cool slightly.
2. Preheat the Oven: Preheat your oven to 180°C (350°F) or 160°C (fan-forced). Grease and line an 8×4 inch loaf tin with baking paper.
3. Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt using a balloon whisk. This helps to aerate and evenly distribute the ingredients.
4. Combine Wet Ingredients: In another bowl, mix the melted butter, eggs, buttermilk, oil, and vanilla extract. Whisk until fully combined.
5. Combine Wet and Dry Ingredients: Make a well in the center of the dry ingredients. Pour in the wet mixture and gently mix using a spatula until no lumps remain. Avoid overmixing.
6. Prepare Chocolate Batter: Transfer about 1½ cups of the batter to the wet ingredients bowl. Add the cocoa powder and boiling water to this portion. Stir gently until combined.

Layering and Baking

7. Layer the Batter: Start by adding ½ cup of vanilla batter to the prepared loaf tin. Add ½ cup of chocolate batter directly on top. Repeat the layers until all the batter is used. Use a knife to lightly swirl the batters together for a marbled effect.
8. Bake: Bake for 45-55 minutes, or until a toothpick inserted into the center comes out with a sticky crumb or two. Keep an eye on the cake to avoid overbaking.
9. Cool: Let the cake cool in the tin for 10 minutes. Use the edges of the baking paper to lift it out and transfer it to a wire rack to cool completely before adding the ganache.

Making the Ganache

10. Heat the Cream: In a small saucepan, heat the cream over low-medium heat until it begins to bubble.
11. Combine with Chocolate: Pour the hot cream over the chocolate in a heatproof bowl. Let it sit for 1 minute to melt the chocolate.
12. Mix: Stir the mixture until smooth. Allow the ganache to cool for 5 minutes, then pour it evenly over the cooled cake.
