No reviews

This Marble Bundt Cake combines rich vanilla and chocolate swirls in a moist, buttery pound cake topped with a glossy ganache glaze. It’s elegant enough for celebrations and easy enough for everyday baking.

  • Total Time: 1 hour 15 minutes
  • Yield: 10–12 servings

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

  1. Preheat oven to 350°F (175°C) and generously grease a Bundt pan.
  2. Cream butter and sugar together until light and fluffy.
  3. Add eggs one at a time, mixing well after each addition.
  4. Mix in sour cream and vanilla until smooth.
  5. In a separate bowl, whisk together flour, baking powder, and salt.
  6. Gradually add dry ingredients to the wet mixture, mixing until just combined.
  7. Divide batter into two bowls. In one bowl, stir in cocoa powder and milk to make the chocolate batter.
  8. Spoon vanilla and chocolate batters alternately into the pan. Swirl gently with a knife to create a marbled effect.
  9. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
  10. Cool cake in the pan for 10 minutes before inverting onto a wire rack to cool completely.
  11. To make the ganache, heat heavy cream until steaming, then pour over chopped chocolate. Let sit for 1 minute, then stir until smooth.
  12. 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.
