Description

This Brownie Cake combines the rich flavors of chocolate cake and fudgy brownies into one decadent dessert. Moist and dense with chunks of chocolate chips throughout, it's topped with a luscious homemade chocolate ganache for the perfect finishing touch. Ideal for special occasions or an indulgent treat, this cake offers a delightful twist on traditional brownies and chocolate cake.


Ingredients

Cake Batter

  • 15.25 ounces chocolate cake mix
  • 18.3 ounces fudge brownie mix
  • 4 large eggs
  • 1¼ cups water
  • 1 cup vegetable oil (or canola oil)
  • ½ cup mayonnaise
  • 1 cup semi-sweet chocolate chips

Ganache

  • 1 cup heavy whipping cream
  • 2 cups chocolate chips


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it’s at the perfect temperature for baking the cake.
  2. Prepare Batter: In a large mixing bowl, combine the chocolate cake mix, fudge brownie mix, eggs, water, vegetable oil, and mayonnaise. Mix well using a spoon or an electric mixer until fully combined. Gently fold in the semi-sweet chocolate chips to evenly distribute them.
  3. Prepare Pan: Lightly spray a 12-cup bundt pan with non-stick cooking spray to prevent sticking. Spread the batter evenly into the bundt pan, smoothing the top as needed.
  4. Bake Cake: Bake in the preheated oven for 45 to 50 minutes. Check doneness by inserting a toothpick into the center; it should come out clean or with just a few moist crumbs attached.
  5. Cool Cake: Allow the cake to cool in the pan for 10 to 15 minutes. Afterward, carefully remove it from the bundt pan and transfer to a cooling rack to cool completely.
  6. Prepare Ganache: Once the cake is fully cooled, heat the heavy whipping cream in a small saucepan over medium heat or microwave it until steam rises but it does not boil.
  7. Combine Ganache: Pour the hot cream over the 2 cups of chocolate chips placed in a small bowl. Cover the bowl with a plate to trap heat and let sit for 2 to 3 minutes, allowing the chocolate to soften.
  8. Whisk Ganache: Whisk the cream and chocolate together until a smooth, glossy ganache forms with a velvety texture.
  9. Glaze Cake: Pour the ganache evenly over the cooled brownie cake, allowing it to drizzle down the sides for an elegant look.
  10. Serve: Slice and serve this rich and indulgent brownie cake at room temperature for the best flavor and texture.

Notes

  • You can substitute vegetable oil with canola oil for a slightly lighter texture.
  • Mayonnaise in the batter helps keep the cake moist and tender.
  • Use high-quality chocolate chips (semi-sweet, milk, or dark) for best flavor.
  • Ganache can be made ahead and refrigerated; rewarm gently before pouring over cake.
  • Ensure the cake is fully cooled before adding ganache to prevent melting.
  • Store leftovers covered at room temperature for up to 3 days or refrigerated for up to 5 days.
