This brownie bundt cake is inspired by my chocolate bundt cake. But instead of making the chocolate cake from scratch, I used a dark chocolate fudge cake mix and added some brownie mix as well. It adds an even richer flavor, giving it that fudgy brownie texture. Then it’s topped with a simple chocolate ganache because, well…the more chocolate, the better, right?!

Why This Brownie Bundt Cake Is Always A Hit

Here are a few reasons why I, and my family, can’t get enough of this cake.

  • Rich chocolate flavor. There’s no shortage of chocolate in this cake! It’s made with chocolate brownies, dark chocolate cake mix, mini chocolate chips, and chocolate ganache. It’s definitely one for the chocolate lovers!
  • Moist, fudgy texture. Bundt cake in general is always a bit dense and moist but this brownie bundt cake takes that to a new level. The texture isn’t quite as dense and fudgy as fudgy brownies but it’s a bit more dense and moist than regular cake.
  • Super easy to make. Since this recipe starts with cake mix and brownie mix, there’s a short ingredients list and even shorter instructions. There’s no need to measure any dry ingredients! It comes together so quickly and easily.

Recipe Ingredients

Using cake mix and brownie mix to start this recipe helps keep the ingredients list short and simple. Scroll down to the recipe card below for the exact measurements.

For the Cake:

  • Brownie mix – I like to use a chewy brownie mix for the perfect texture in this bundt cake.
  • Cake mix – I used a dark chocolate fudge cake mix which adds a rich chocolate and fudgy flavor to the cake.
  • Eggs
  • Water
  • Vegetable oil – Adds moisture to the cake. Coconut oil can also replace vegetable oil if you want a slight twist in flavor.
  • Sour cream – Adds moisture and a bit of tangy flavor to offset the richness. If you’re out of sour cream, Greek yogurt works perfectly
  • Semi-sweet chocolate chips – I used mini chocolate chips so they dispersed more easily and evenly in the batter.

For the Ganache Topping:

  • Heavy cream – Helps make the ganache pourable.
  • Semi-sweet chocolate chips – I recommend using a quality brand like Hershey or Ghirardelli for the best flavor.

How To Make Brownie Bundt Cake

This bundt cake is super easy to make. It just requires time for the cake to cool before adding the ganache. The printable version of the instructions can be found in the recipe card below.

  • Prep. Preheat the oven to 350F. Grease the bundt pan generously.
  • Make the batter. Combine the cake and brownie mixes, eggs, water, oil, and sour cream in a bowl until smooth. Gently fold in the chocolate chips.
  • Bake. Pour the batter into the prepared pan. Bake for 50 minutes, until a toothpick inserted in the center comes out with just a few crumbs.
  • Cool. Let the cake cool in the pan for about 15 minutes, then carefully invert it onto a wire rack. Cool completely.
  • Make the ganache. Heat the heavy cream until it just starts to simmer. Pour over the chocolate chips in a bowl then stir until smooth and shiny. Drizzle it over the cooled cake.

Tips for the Perfect Bundt Cake

Here are a few things to keep in mind to help you make the perfect brownie bundt cake.

  • Smooth the batter. When pouring the batter into the pan, smooth it out on the top with a spatula then give the pan a couple of taps on the counter. This helps settle the batter and remove any bubbles.
  • Don’t overbake. The key to a dense, fudgy brownie bundt cake is to not overbake it. A toothpick inserted in the center should come out with a few crumbs but no wet batter.
  • Try a different mix-in. For different variations, you can replace the mini chocolate chips with peanut butter chips, butterscotch chips, or even chopped walnuts.
  • Other topping ideas. If ganache isn’t your thing, try a dusting of powdered sugar or a drizzle of caramel.

Serving Suggestions

For an extra indulgence, add a dollop of whipped cream or a scoop of vanilla ice cream on the side. A few fresh berries can also add a nice pop of color and flavor.

Proper Storage

  • Room temperature. Brownie bundt cake can be stored in an airtight container at room temperature for up to 3 days.
  • Fridge. It can also be stored in the fridge for up to 5 days. Just keep it tightly covered in an airtight container.
  • Freezer. I like to flash freeze slices of the cake to harden the ganache then wrap them tightly in plastic wrap. Freeze for up to 3 months. Thaw in the fridge or on the counter.
