NOTES
We have had a few comments from our readers who have said some of the batter spilled over in the oven. Please please make sure you DO NOT NO NO NO use the ingredients listed on the box mixes, just the ingredients listed below.
Then you should be absolutely fine with no chocolate fudge volcanic eruptions happening in your oven!
Some of our readers have made this just on its own, some have added the frosting and others have made up their own frosting recipe. Whichever way you decide to make this, please enjoy!
And if you're baking for just one or two people, why not cut the cake into slices and wrap individually and freeze. At least you'll have a nice little supply of nanny's cake to hand when you get that craving!
In the photo below, Nanny's sliced some of her chocolate fudge brownie cake and put in boxes to take for friends. Of course, they all loved it!

Last week I made nanny's chocolate fudge brownie cake but added an Easter touch to it. I was going to a school reunion and since it's coming up to Easter I thought what better than to bring a cake along for my old school friends to enjoy!
The photo below just gives you an idea of how you can decorate it for any occasion, Easter included!
Note: you do need to make sure the little chocolate eggs have set into the frosting before transferring to a plate/container otherwise they will roll off if the frosting is still wet!

Here's Nanny's chocolate fudge cake made by one of our readers, made this for her son's 14th birthday, like a UFO Spaceship. It looks great!

Charles H
says:I add 1 cup of cake flour (cake mix boxes are smaller now) 3 1/2 oz chocolate pudding, replace water with chocolate milk, add 1 cup chopped pecans to the mix(toss with flour), add 1 cup pecans in bottom of bundt pan before adding the batter, Cook 325° for 1:15, turn oven off let the cake sit with door closed for 5-10 minutes, remove from oven let cake cool, pour chocolate ganache over cake…… very moist
Charles
says:I add 3 1/2 oz chocolate pudding to the recipe, I bake mines at 325° for 1:15 bundt pan, turn oven off with oven door close let it sit for 5-10 minutes , comes out really moist
Karen
says:I have two 6” bundt pans. Can I divide this cake so I can share one? We’re seniors and can’t eat a whole cake but I love to share with elderly neighbors. How would you adjust the baking time for the smaller pans? Thanks in advance for any help.
Lovefoodies
says:Hi Karen, try reducing the cook time by around 8-10 minutes and keep checking. That should do the trick!
Susan Logan
says:Does anyone know if high altitude adjustments are needed for this recipe? The recipe says not to follow box instructions, which do make adjustments for high altitude. I made this in Kansas and Colorado. In Colorado, there’s a trough in the cake. Still delicious, but seems to have a different consistency.
Lovefoodies
says:Hi Susan, sorry to find the cake wasn’t the same in high altitude. For the recipe where it says not to follow the box instructions, it was because a lot of people were adding ALL the ingredients stated on the box and also those in nanny’s recipe so you can imagine the ratios would be wrong!!
For the baking temperature / time, it is probably a good idea to take note of any recommendation for high altitudes and just keep an eye on the cake whilst it’s baking, just make sure you don’t follow any instructions for adding any of the other ingredients like egg etc that is on the box!
candi counts
says:I just made this brownie cake I live in Colorado springs and I adjusted the recipe instead of using 1 1/4 cups of water I didn’t add the 1/4 and used milk instead of water..and I added an additional 2 Table spoons of flour..kept everything else the same and the cooking time was only for about 45 mins It was enough for one bundt pan and 8 cupcakes
Polly Walker
says:I am trying this recipe with a GF cake mix and a GF brownie mix. I will let you know how it works out.
Polly Walker
says:I made this GF with a GF cake mix amd GF brownie mix. With the exact ingredient proportions as the original recipe. And it turned out great and was delicious!
I would include a photo but I do not see how.
Yvonne Sinchuk

Ads are intrusive
says:Hate this website. So many ads it’s almost impossible to follow the blog post. I can get better recipes elsewhere.
Sheila
says:Made this recipe last night using the exact ingredients and it turned out great. It even looks just like her picture which is ever unusual because none of my recipes ever turn out just like there. I truly will be using this as a go too. After reading some of the remarks I was surprised mine did not over flow or under bake. I too used I leaf type Bundt pan and it was done in correct amount of time. Thank You so much for sharing your recipe, please continue to send me more.
Ruth Banes
says:This cake was delish. I only changed one ingredient, I put a box of instant chocolate pudding 3 1/2 oz box, jello brand. Awesome cake.
Christinefaith
says:I followed the recipe exactly, except I used 2% milk instead of water. I baked it at 350 degrees and it was done at 45 mins. It came out dry. ? Any suggestions???
teri farmer
says:you didn’t follow the recipe exactly if you used milk instead of water.
Mary
says:Easy to follow directions, family LOVED it!
Sarah J
says:Can this recipe work in round or square cake pans for a Grooms cake?
Patty
says:I make this cake all the time! I take it to every function. I substitute Starbucks Breakfast Blend for the water and Ghiradelli brownie mix and make a homemade caramel icing to drizzle over the cake. I make thus cake so often I buy the big box of Ghiradelli brownie mid at costco
The last two events I made this cake for were auctions and the cakes went for $100 each!
Holly
says:I’m making this recipe right now for the first time!
Patty – that sounds so amazing! Would you be willing to share your homemade Caramel icing? I would love to try it with this recipe!
Thanks!
Lovefoodies
says:Hi Holly, Thanks for writing in. Just in case Patty doesn’t reply (not everyone chooses to get a notification on the comments!), we have a fabulous caramel icing recipe here, (just head straight to the icing part of the cake recipe). https://lovefoodies.com/caris-oatmeal-cake-and-caramel-icing/ . It’s all homemade and very popular. The quantity in the recipe will need to be halved as I think it will be way too much for a bundt cake. Hope that helps and happy baking!
Tanya
says:This is my go to chocolate cake, I’ve tweaked it a few ways to make it my own, like adding an egg, using milk instead of water (even chocolate milk), and butter instead of oil. I make ganache also instead of store bought icing, I get rave reviews. Never dry and doesn’t overflow. Love this cake.
Claudia
says:This cake was very delicious! Very moist! Will definitely be making again.
