Deliciously moist, soft, and buttery pound cake that is both vanilla and chocolate swirled together to create a beautiful marble effect. This cake is the best of both worlds!
Preheat the oven to 180C/350F/Gas 4. Grease a 9x5-inch loaf pan and line with parchment paper. Set aside.
In a large mixing bowl, beat together the butter and sugar until light and fluffy.
Add the eggs and mix until completely combined. Add the vanilla and sour cream, and mix until just combined.
Add the flour and salt, and gently fold in until completely combined and no pockets of flour remain.
Pour half of the batter into a separate bowl and fold in the cocoa powder.
Alternating between the vanilla batter and the chocolate batter, add scoops to the prepared pan until both mixtures are used up.
Using a knife or a cake tester, swirl the two mixtures together.
Bake for 50 - 60 minutes, or until a toothpick inserted into the centre comes out clean.
Leave the cake to cool completely in the pan on a wire rack before slicing and serving.
