Substitutions and Variations
Skip the ganache: If you don’t want to make homemade ganache, warm a can of chocolate frosting in the microwave for a few seconds until it’s pourable. It spreads beautifully over the cake for the same glossy finish.
Add some crunch: Stir chopped walnuts or pecans into the batter before baking, or sprinkle them over the top of the ganache for extra texture and flavor.
Try a coconut twist: If you love coconut, mix a little into the ganache or sprinkle shredded coconut on top for a sweet, chewy touch.
Please note: This recipe uses TWO cake mixes. Do not follow any of the directions on the back of the boxes and only add the ingredients I have listed below in the recipe card.
Step-by-Step Directions
This section provides step-by-step photos and instructions to guide you through the recipe. For the complete printable version, scroll down to the recipe card below.
Step 1: Add all the cake ingredients to a large bowl and mix for a few minutes with a stand or hand mixer.
Step 2: Pour the batter into a greased bundt pan and bake for 50–55 minutes.
What Size Cake Pan to Use?
For this recipe, I used a 12 inch, 12 cup capacity bundt cake pan.
Nordic Ware Original Bundt, 12-Cup, Graphite
Step 3: Check the cake around 45 minutes by inserting a toothpick or skewer—if it comes out clean or with a few crumbs, it's done. Let the cake cool in the pan for 5 minutes, loosen the edges with a knife, then turn it out onto a rack and cool completely before glazing.
Chocolate Ganache Recipe
Step 4: Heat heavy cream in a microwave-safe bowl for about 2 minutes, just until it begins to boil, then add chocolate morsels and let sit for 5 minutes. Whisk until smooth and shiny—at first it may look separated, but keep stirring and it will come together.
Step 5: Pour the glaze over the cooled cake, letting it drip down the sides. Since it's very rich, you may want to save some—it's perfect over ice cream later.
Insider Tips from My Kitchen to Yours
✔️ DO use a 10–12 cup Bundt pan, start checking at 45 minutes, and let the cake cool completely before adding the ganache.
❌ DO NOT follow the instructions on the cake or brownie mix boxes or overheat the cream. Warm it until steaming, not boiling.
Storing and Thawing Tips
Refrigerator: It's best to store any leftover in the refrigerator for up to five days in an airtight container to keep it fresh and prevent the ganache from melting.
Freezer: You can freeze the cake for up to one month. First wrap the cake tightly in plastic wrap or aluminum foil and place it in an airtight freezer bag before placing it in the freezer.
Thawing Tips: When ready to eat and enjoy the cake, allow the cake to thaw in the refrigerator overnight before serving the next day.

To make brownie mix more cake-like, add 1–2 teaspoons of baking powder for fluffiness and ⅓ cup of oil or melted butter for extra moisture. Then, prepare and bake the mix according to the package instructions.
A single box of brownie mix usually fits an 8x8 or 9x9-inch pan, while two boxes need a larger 9x13-inch dish. Always check the box for specific pan size and baking time, as they can vary by brand.

I made this cake today for our dinner. It turned out great. I did use a sugar free cake mix and brownie mix. It didn’t make any difference.

I large bundt cake is a bit much for just hubby and myself, so I make into cupcakes or will use my mini bundt cake pan and make individual bundt cakes; putting some in the freezer to have for another time or will share with our neighbor.

Thank you for the wonderful comment!

Mistakenly purchased a supreme brownie mix, so it included chocolate chips, and used it to make this cake. This was a delightful mistake and will continue the recipe with this small adaption. Thanks for sharing!
Lois says
Thank you for the great comment!

I haven't made it yet. But it looks delicious and easy. I can't wait. I have to go buy a couple things. I'm definitely going to make it. I have a bundt pan I haven't used in a very long time! I usually make cupcakes or a 9×13 cake. I'll shock my son with something different! LOL

I'm planning to make the Pumpkin Pinata cake (2 bundt cakes stacked together (bottom one upside down) with candy in the middle. Do you think this cake sturdy enough for this? Or is it too moist to hold up?
Lois says
I think it might the cakes might be too moist, but you never really know until you try, right? Let me know how it came out!
