Ingredients You’ll Need
Don’t let the long list intimidate you — each ingredient here plays a crucial role in building layers of flavor and texture, creating that dream combo of moist cake and rich brownie all in one. The simplicity of these staples lets the chocolate shine brilliantly in every bite.
- Chocolate cake mix (1 box, 15.25 ounces): Provides the tender, fluffy cake base with deep chocolate notes.
- Fudge brownie mix (1 box, 18.3 ounces): Delivers that dense, fudgy texture that brownie lovers crave.
- Large eggs (4, room temperature): Essential for binding the batter and lending richness.
- Water (1¼ cups, room temperature): Keeps the batter moist and smooth.
- Vegetable oil (1 cup): Adds moisture and helps achieve a tender crumb.
- Heavy whipping cream (1 cup): Key to making the luscious ganache topping smooth and creamy.
- Semi-sweet chocolate chips (12 ounces): Melting these into the cream creates the rich ganache that finishes the cake perfectly.
How to Make Chocolate Brownie Cake with Rich Ganache Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350°F (177°C). Grease a 10-inch Bundt pan generously with nonstick spray to ensure the cake releases easily after baking. This first step is important for a flawless final presentation.
Step 2: Mix the Batter
In a large bowl, whisk together the chocolate cake mix and fudge brownie mix thoroughly. Add the eggs, water, and vegetable oil, continuing to whisk until the batter is smooth and well combined. This blend of mixes creates the perfect balance of cakey and fudgy textures.
Step 3: Bake the Cake
Pour the batter evenly into the prepared Bundt pan, smoothing the surface lightly. Place it in the oven and bake for 50 to 55 minutes. The cake is done when a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it, signaling that fudgy richness.
Step 4: Cool the Cake
Allow the cake to cool in the pan for 10 minutes to set and become stable enough to remove. Then gently invert onto a cooling rack and let it cool completely before decorating. Patience now means a neater ganache finish later!
Step 5: Prepare the Rich Ganache
While the cake cools, heat the heavy whipping cream in a microwave-safe bowl until it just begins to simmer. Pour this hot cream over the semi-sweet chocolate chips and let it rest for 5 minutes. Then whisk until the mixture is glossy and silky smooth. The ganache should be thick yet pourable for drizzling.
Step 6: Drizzle the Ganache
Finally, generously drizzle the ganache over the fully cooled cake. Allow it to set for a few minutes so it hardens slightly but remains glossy and indulgent. This finishing touch brings the whole Chocolate Brownie Cake with Rich Ganache Recipe together into one irresistible treat.
How to Serve Chocolate Brownie Cake with Rich Ganache Recipe

Garnishes
Feel free to elevate presentation with fresh raspberries, a dusting of powdered sugar, or a sprinkle of flaky sea salt on top of the ganache. Each addition adds a burst of color and an extra layer of flavor to complement the intense chocolatey richness.
Side Dishes
Pair your slice with a scoop of vanilla bean ice cream or a dollop of lightly whipped cream to add a creamy contrast. Fresh berries or a drizzle of salted caramel sauce can also bring delightful complexity alongside the dense cake.
Creative Ways to Present
Serve this cake as the centerpiece on a rustic wooden board surrounded by small bowls of nuts, chocolate shavings, and assorted berries for a dramatic effect. For celebrations, add edible gold leaf or chocolate curls for a luxurious twist that wows every guest.
Make Ahead and Storage
Storing Leftovers
Store any leftover Chocolate Brownie Cake with Rich Ganache Recipe tightly covered at room temperature for up to 2 days or in the refrigerator for up to 5 days. The ganache keeps the cake moist, but refrigeration will extend freshness if needed.
Freezing
You can freeze the cooled unfrosted cake tightly wrapped in plastic wrap and aluminum foil for up to 3 months. When ready, thaw at room temperature and freshly prepare the ganache to drizzle over the cake for best texture and flavor.
Reheating
To enjoy a slice warm, reheat individual portions in the microwave for 15 to 20 seconds. This softens the ganache beautifully and brings out the gooey brownie quality that makes this recipe so addictive.
FAQs
Can I use homemade cake and brownie mixes instead of boxed ones?
Absolutely! While boxed mixes simplify the process, you can use your favorite homemade chocolate cake and brownie recipes to maintain the luscious texture and flavor.
Is this recipe gluten-free?
Since it relies on boxed cake and brownie mixes, it is not naturally gluten-free unless you use gluten-free mixes specifically formulated for baking.
How do I know when the cake is done baking?
The best test is inserting a toothpick into the center: it should come out clean with just a few moist crumbs attached, signifying fudgy but fully cooked cake.
Can I substitute the vegetable oil with butter?
Yes, melted butter can be swapped for vegetable oil, which will add richness but might slightly change the texture. Use an equal amount for best results.
How thick should the ganache be when drizzling?
It should be thick enough to coat the back of a spoon but still fluid enough to pour slowly over the cake. Too hot and it will be runny; let it cool slightly to achieve the right consistency.
