Ingredients You’ll Need
The ingredients for this recipe are wonderfully simple yet essential for creating the perfect balance of flavors and textures. Each one plays a key role, from the rich cake and brownie mixes to the luscious ganache that ties everything together beautifully.
- Chocolate cake mix: Provides a tender, moist base that’s full of chocolate flavor.
- Fudge brownie mix: Adds fudgy density and that classic chewy brownie texture we all crave.
- Large eggs (4): Bring structure and richness to the batter, ensuring a perfect rise.
- Water (1¼ cups): Keeps the cake moist and helps blend the mixes smoothly.
- Vegetable oil (1 cup): Adds tenderness and keeps the cake perfectly moist without weighing it down.
- Heavy whipping cream (1 cup): The star of the ganache, yielding a smooth, creamy topping.
- Semi-sweet chocolate chips (12 ounces): Melted into the cream to create the rich ganache that’s the ultimate chocolate finish.
How to Make Chocolate Brownie Cake with Rich Chocolate Ganache Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350°F (177°C). Get a 10-inch Bundt pan ready by coating it generously with nonstick cooking spray to ensure your cake releases perfectly after baking.
Step 2: Mix the Batter
In a large bowl, whisk together both the chocolate cake mix and fudge brownie mix along with the eggs, water, and vegetable oil. Whisk until you achieve a smooth, thick batter with no lumps. This blend is what creates that remarkable marriage between cake and brownie textures.
Step 3: Bake to Perfection
Pour the luscious batter into your prepared Bundt pan, spreading it evenly. Place it in the oven and bake for 50 to 55 minutes. You’ll know it’s done when a toothpick poked into the center comes out clean with only a few moist crumbs attached—this guarantees a perfectly fudgy but cooked-through center.
Step 4: Cool the Cake
Remove the cake from the oven and let it rest in the pan on a cooling rack for about 10 minutes. This rest time allows it to firm up slightly, so it releases cleanly from the pan. Then, gently invert it out and allow it to cool completely before adding the ganache.
Step 5: Make the Rich Chocolate Ganache
While the cake cools, heat the heavy whipping cream in a microwave-safe bowl until it’s just simmering. Pour the cream over the semi-sweet chocolate chips and let the mixture sit undisturbed for five minutes. Then whisk vigorously until the ganache is perfectly smooth and glossy—this creamy topping is what elevates the cake into pure indulgence.
Step 6: Finish and Drizzle
Once your cake is completely cooled, slowly drizzle the ganache over the top, allowing it to cascade down the sides naturally. Let it set for a bit so the ganache thickens just enough to hold beautifully before you slice and serve.
How to Serve Chocolate Brownie Cake with Rich Chocolate Ganache Recipe

Garnishes
A dusting of powdered sugar or a sprinkle of finely chopped toasted nuts like pecans or walnuts can add a delightful contrast in texture and a touch of elegance. Fresh berries also complement the deep chocolate flavors beautifully, adding brightness and color to your presentation.
Side Dishes
This chocolate brownie cake pairs wonderfully with a scoop of vanilla bean ice cream or a dollop of whipped cream to balance the richness. For an adult twist, serve it alongside a small glass of port or a bold, dark coffee that cuts through the sweetness perfectly.
Creative Ways to Present
Try serving slices of the cake on individual dessert plates with artistic swirls of raspberry or caramel sauce. For gatherings, consider layering a slice with some fresh fruit and whipped cream in a glass for a charming deconstructed take on the Chocolate Brownie Cake with Rich Chocolate Ganache Recipe.
Make Ahead and Storage
Storing Leftovers
After enjoying this decadence, store any leftovers in an airtight container at room temperature for up to 2 days. For longer freshness, refrigeration is best and will keep your cake moist, but allow it to come to room temperature before serving for maximum enjoyment.
Freezing
You can freeze slices of the cake individually by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag or container. Freeze for up to 3 months. Thaw overnight in the fridge and let sit at room temp before enjoying with that luscious ganache.
Reheating
If you want to warm up a slice, gently heat it in the microwave for 15-20 seconds, just enough to soften the ganache slightly and release those irresistible aromas. Be careful not to overheat, or the ganache may become too runny.
FAQs
Can I use homemade cake and brownie batter instead of mixes?
Absolutely! While the mixes make this recipe incredibly quick and foolproof, homemade batters will give you full control over ingredients and flavor. Just be sure to maintain the same ratios and consistency for the best results.
Is this recipe suitable for a Bundt pan only?
Although the recipe is designed for a 10-inch Bundt pan, you could bake it in another pan shape like a 9×13-inch baking dish. Adjust the baking time accordingly and check doneness frequently with a toothpick.
What’s the difference between this cake and a traditional brownie?
This Chocolate Brownie Cake with Rich Chocolate Ganache Recipe blends the best elements of both cake and brownie textures—lighter than a typical brownie yet denser and fudgier than an ordinary chocolate cake.
Can I use a different type of chocolate for the ganache?
Yes! Semi-sweet works beautifully, but you can experiment with bittersweet or even milk chocolate depending on how intense or sweet you want the ganache to be.
How can I make the ganache glossy and smooth every time?
Patience is key. Let the hot cream sit on the chocolate chips undisturbed before whisking. Use high-quality chocolate and don’t overheat the cream to avoid seizing or graininess in the ganache.

- For a richer ganache, you can substitute half the semi-sweet chocolate chips with bittersweet chocolate.
- Make sure the cake is completely cool before adding ganache to prevent it from melting and running off.
