Marble Loaf

Preheat oven to 180°C. Grease a baking tray with butter and dust with flour.

In a bowl, sieve together flour, baking powder, and salt. Set aside.

Whisk together butter, sugar, and oil until creamy.

Add eggs one at a time while whisking. Add vanilla essence and continue whisking.

Fold in the dry ingredients and mix until combined. Add buttermilk and continue mixing.

Divide the batter in half. Place half of the batter in another bowl and add cocoa powder and hot chocolate. Mix until combined.

Pour the white mixture into the bottom of the tray. Add the chocolate mixture randomly and mix slightly to create a marble effect. Pour the remaining white mixture on top.

Place chocolate chunks on top of the cake and bake for 30-35 minutes until a toothpick inserted in the center comes out clean.
