Ingredients

Cake Ingredients

  • 1 (13.25 oz) box Devil’s Food Cake Mix
  • 1 (3.9 oz) box instant chocolate pudding
  • 3 large eggs
  • ⅔ cup brewed coffee
  • 8 oz sour cream
  • ½ cup vegetable oil
  • 2 tablespoons dark rum
  • 1 ½ cups chocolate chips

Ganache

  • 8 oz quality semi-sweet chocolate, chopped
  • 1 ¼ cup heavy cream

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C) and thoroughly grease a standard bundt pan to ensure the cake releases easily after baking.
  2. Mix wet ingredients: In a large mixing bowl, whisk together the eggs, sour cream, vegetable oil, brewed coffee, and dark rum until the mixture is smooth and well combined.
  3. Combine dry ingredients: Gradually add the Devil’s Food cake mix and instant chocolate pudding mix into the wet ingredients, mixing slowly to avoid overbeating. Then gently fold in the chocolate chips to evenly distribute them throughout the batter.
  4. Bake the cake: Pour the batter into the prepared bundt pan, smoothing the top with a spatula. Bake in the preheated oven for 50 to 55 minutes, or until a toothpick inserted into the center comes out with moist crumbs but no raw batter.
  5. Cool the cake: Remove the cake from the oven and allow it to cool completely in the pan to set before removing. This will take about 30 to 45 minutes.
  6. Prepare ganache: While the cake cools, heat the heavy cream in the microwave for about 80 to 90 seconds or on the stovetop until it is hot but not boiling. Place chopped semi-sweet chocolate in a small bowl, then pour the warmed cream over it. Let it sit for 1 minute, then stir gently until the ganache is smooth and glossy.
  7. Finish and serve: Carefully invert the cooled cake onto a serving plate. Drizzle the prepared chocolate ganache generously over the top and sides of the cake. Slice and serve to enjoy the rich, moist chocolate delight.

Notes

  • Using brewed coffee enhances the chocolate flavor but can be substituted with hot water for a milder taste.
  • The dark rum adds aroma and richness but can be omitted or replaced with vanilla extract.
  • Ensure the cake is fully cooled before adding ganache to prevent it from melting and running excessively.
  • Use high-quality chocolate for the ganache for the best flavor and texture.
  • You can bake this cake in other pans but adjust baking time accordingly.
