Chocolate Brownie Cake

  • 1 box chocolate cake ( I used Duncan Hines chocolate fudge)
  • 1 box brownie mix I used Duncan Hines chewy fudge
  • 4 eggs room temperature
  • 1 cup vegetable or canola oil
  • cup sour cream
  • 1 cup water


  • 1 cup heavy whipping cream
  • 1 bag 12 ounces semi sweet chocolate morsels



  • Heat oven to 350°. Prepare a bundt pan by spraying with bakers spray or butter and flour.
  • In a stand mixer bowl or large bowl, pour in all cake ingredients. Start the mixer on slow and then turn up to medium and mix for 2 minutes.
  • Pour batter into prepared bundt pan and bake for 50 to 55 minutes.
  • When done baking, remove the cake and allow it to cool in the pan for 5 to 10 minutes. Then carefully turn the cake out onto a cooling rack and cool for at least 30 minutes.

Chocolate Ganache

  • Place heavy whipping cream in a large microwave-safe bowl. Heat for 2 minutes or until just boiling.
  • Carefully pour in chocolate morsels into the cream. Let sit for 5 minutes.
  • Whisk chocolate and cream until the chocolate is smooth and shiny. This takes about 1 minute.
  • Pour over cooled cake.


  • Do not add the ingredients to the cake or brownie mixes. Use the dry cake mix in this recipe.
  • If using a dark nonstick coated pan, bake at 325°.
  • Do not overbake. If you find your cakes turn out dry it's likely you are overbaking.
