This cake is a decadent fusion of desserts that results in a moist, rich, and intensely chocolatey dessert.

Key ingredients such as chocolate cake mix with pudding, eggs, oil, mayo, and chocolate chips create a lusciously textured cake with pockets of molten chocolate.

The crowning finish is a velvety ganache made from heavy cream and chocolate chips, adding a smooth, creamy contrast and a touch of elegance to this indulgent treat.

You’ll need:

For The Cake:

  • 1 (15.25-ounce) box of chocolate cake mix (Any chocolate cake mix should do. I always use Betty Crocker – it has pudding in the mix.)
  • 1 (18.3-ounce) box of fudge brownie mix
  • 4 large eggs
  • 1¼ cups of water
  • 1 cup of vegetable or canola oil
  • ½ cup of mayonnaise
  • 1 cup of chocolate chips, I used semi-sweet chocolate chips, but you could use any milk or dark chocolate

For The Ganache:

  • 1 cup of heavy whipping cream
  • 2 cups of chocolate chips

Substitutions And Additions

MAYONNAISE: You can use Greek Yogurt as a mayo substitute. It has the same tangy taste and texture as mayo.

CHOCOLATE CHIPS: Get creative with your chocolate chips. White chocolate, butterscotch, or mint chocolate chips can add unique and delightful flavors to your cake while keeping it gooey and delicious.

TOPPINGS: You can use sprinkles to top this chocolate Bundt cake if you desire.

CAKE AND BROWNIE MIX: We love using the Ghirardelli brownie mix or Duncan Hines moist cake mix for this chocolate cake!

How To Make Chocolate Brownie Cake Recipe

Once you whip up the chocolatey batter for this cake, it gets baked to the perfect texture before you are ready to dig in.

STEP ONE: Preheat your oven to 350°F.

STEP TWO: In a large bowl, combine the box of cake mix, the box of brownie mix, eggs, water, oil, and mayonnaise.

Stir or mix these ingredients with an electric mixer until it’s well combined. Fold in the chocolate chips and keep stirring until they are well mixed in.

STEP THREE: Lightly spray a 12-cup Bundt pan with a non-stick cooking spray and pour the batter in evenly. 

PRO TIP:

Please note that it is very important that you are using a 12-cup Bundt pan for this recipe. If you are using a smaller pan, it will take longer than the indicated time to cook.

STEP FOUR: Bake your cake for 45 to 50 minutes or until a toothpick comes out of the center of the cake clean, or with just a few crumbs.

STEP FIVE: Cool your cake for 10 to 15 minutes and remove it from the Bundt pan to cool the rest of the way on a cooling rack.

PRO TIP:

Carefully run a rubber spatula around the sides and center of the Bundt pan before removing the cake to help it come out cleanly. Place a cooling rack on top of the Bundt pan and then invert it to remove the cake from the pan.

STEP SIX: When the cake is cooled, prepare the ganache.

STEP SEVEN: To start your ganache, heat the heavy cream in a small saucepan or in a microwave-safe container until it’s steaming.

PRO TIP:

Don’t allow your cream to boil! When it’s steaming, it’s ready.

STEP EIGHT: Pour the cream over the chocolate chips in a small bowl.

STEP NINE: Cover your chocolate with a plate for two to three minutes to contain the heat and allow the chocolate chips to soften.

STEP TEN: Whisk until the melted chocolate mixture forms a smooth, glossy ganache.

STEP ELEVEN: Pour the ganache over the cake and serve.

PRO TIP:

Place a clean baking sheet under the wire cooling rack before pouring the ganache over so that the drips are caught for easy cleanup.

How To Serve This Fudgy Brownie Cake

Add a scoop of our no-churn vanilla ice cream to your chocolate fudge brownie cake. This rich chocolate cake is ideal for a special occasion, especially if you are celebrating a chocolate lover.

Pair your chocolate brownie cake with a steaming cup of freshly brewed coffee or pumpkin spice latte. The bitterness of the coffee complements the sweetness of the cake, creating a perfect balance.

Brownie Cake Mix Recipe FAQ

Can I make this recipe in a regular cake pan instead of a Bundt pan?

This great recipe could be made in a regular pan if you don’t have any Bundt cake pans but keep in mind that you will have to adjust the amount of time the cake bakes.

Can I freeze this chocolate cake?

You can freeze your chocolate brownie cake for up to one month.

Can I frost this with chocolate buttercream or another chocolate frosting instead of ganache?

If you prefer different frosting, you are more than welcome to replace the ganache with frosting or buttercream. It will be just as decadent and delicious.

What is the difference between chocolate cake and brownie cake?

The difference between chocolate cake and brownie cake is that the brownie cake tends to be denser, while the chocolate cake will be fluffier due to the differences in ingredient quantities.

What is the difference between brownie mix and cake mix?

A cake mix will contain more leavener to make it rise and become fluffy and airy, while a brownie mix contains very little, resulting in a denser cake.

    This was fabulous! I made it 3 times in 5 days. First time, exactly as written. I had trouble getting it out of the pan so second time I used cooking spray and cocoa powder to help. Was great! The third time I made it into cake layers! I had some extra batter so made 4 muffins. It was fabulous each time. Great recipe!

  5. Dawn Bradley says

    For the chocolate chips that are used in the cake, I’d use mini chips. For the ganache, I’d add a tsp of vanilla bean paste! I’m going to make this on Tuesday for my son & daughter-in-law!

  24. Nicole Fortier says

    5 stars
    I think that putting caramel on it would be amazing.
    I have a tendency to use more chocolate chips than the recipe calls for.
    It might be delicious with something fresh mint, pineapple, black berries or cherries.
    Could also be amazing with cream cheese frosting and cherries.

  25. Marleen Ngirucherong says

    5 stars
    I always try the recipe as is before I try to change it. I love this chocolate brownie cake as is. What I did was setup a topping bar and let people top their slice with whatever they want. It was a hit. Thank you for always sharing awesome recipes. I’m going down my list making recipes that we chose to make.

  26. Pat Koch says

    I’d add the fruit only as extra decoration drooping the cake. I may add the chocolate chips onlt if I thought it might need it on my second time that I baked the cake!!

  27. Ellen Maddaloni says

    5 stars
    Ahhh. What a beautiful cake thinking the warm Raspberries but then the Ganache puts it over the top it’s all about the finish .
    Thank you for sharing.
    Ellen

  28. Susan says

    This brownie cake sounds amazing! Too bad (or good thing!) it’s Sunday night and I don’t have time to make it now. Haha!😂
    I would probably stir in Skor bits, drizzle with caramel sauce then garnish with some more Skor bits! And of course it would include the vanilla ice cream. That is not negotiable!

    *I’ve not found Skor bits in the US (similar to Heath bits but waaaay better) just in Canada!

  29. Ms AL Warren says

    5 stars
