This is one of my favourite cakes because it is the best of both worlds. It has a great soft vanilla cake and a nice chocolate cake through it, you too are going to love this cake. The good thing about this recipe is you will only make one batter then divide it and flavor one batter with chocolate. Start by preheating your oven to 350 degrees Fahrenheit.

You will need 4 pieces of semi-sweet chocolate for this recipe, break the chocolate place it in a heatproof bowl and place it in a microwave to melt, stir the chocolate every 15 seconds that way your chocolate will not be too hot. Once melted, set the chocolate aside to cool down and prepare the cake batter. In a large mixing bowl, add one stick of softened butter and add sugar then using an electric mixer, cream together the sugar and butter until they are well combined and creamy.

Once nicely combined, add vegetable oil and the oil is what makes this cake remain super moist for a long. Mix the oil in then add 4 large eggs one at a time and stir well after each addition then add vanilla extract for flavouring and mix it in. You will need a separate bowl for the dry ingredients and to that add flour, baking powder and salt mix that together then gradually add the flour mixture in small additions to the wet mixture alternating the flour with buttermilk.

Use a spatula to combine everything until the flour is just combined, remember not to overmix the batter. Take half of the cake batter and put it in a separate bowl then bring the cooled melted chocolate and stir it into half of the batter and gently stir it in until you get a homogenous batter. You will need a loaf pan for this recipe, it is a lot of butter so you will need two pans or you can bake the cake in batches.

Grease and line the bottom of the pan with parchment paper then add the batter into the pan alternate dolloping vanilla and chocolate batter and try to be as evenly as possible once you have added the batter take a knife and swirl it through the batter and give your cake those pretty marble swirls when baked.

Bake the cake in 350 degrees Fahrenheit oven and bake for 30 to 35 minutes or until a toothpick inserted at the centre comes out clean. Let the cake cool for about 10 minutes in its pans before removing it onto a wire rack and cooling it before serving the cake. This is a soft, moist buttery cake and you are going to love it. Bon Appetit.
