Ingredients
- 1 cup unsalted butter, slightly cooler than room temperature
- 2 cups sugar
- 4 large eggs, room temperature
- 1 cup full-fat sour cream
- 2 tsp vanilla extract
- 2 1/2 cups all-purpose flour
- 2 tsp baking powder
- 1/2 tsp salt
- 1/4 cup cocoa powder
- 2 tbsp milk (for chocolate batter)
- 1/2 cup heavy cream
- 4 oz dark or semi-sweet chocolate, chopped (for ganache)
Instructions
- Preheat oven to 350°F (175°C) and generously grease a Bundt pan.
- Cream butter and sugar together until light and fluffy.
- Add eggs one at a time, mixing well after each addition.
- Mix in sour cream and vanilla until smooth.
- In a separate bowl, whisk together flour, baking powder, and salt.
- Gradually add dry ingredients to the wet mixture, mixing until just combined.
- Divide batter into two bowls. In one bowl, stir in cocoa powder and milk to make the chocolate batter.
- Spoon vanilla and chocolate batters alternately into the pan. Swirl gently with a knife to create a marbled effect.
- Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
- Cool cake in the pan for 10 minutes before inverting onto a wire rack to cool completely.
- To make the ganache, heat heavy cream until steaming, then pour over chopped chocolate. Let sit for 1 minute, then stir until smooth.
- Drizzle ganache over the cooled cake and let it set before serving.
Notes
- Use Greek yogurt or buttermilk as a sour cream substitute.
- Dust with powdered sugar instead of ganache for a lighter version.
- Mini Bundt pans work for individual servings—adjust baking time accordingly.
- Add espresso powder for a mocha twist or orange zest for brightness.
- Cool cake fully before glazing to avoid melting the ganache.
