Chocolate Brownie Cake is one of the easiest chocolate cakes I have ever made, but also one of the most delectable! I bake it for every occasion, including holidays. Be sure to check out more of my Cake Recipes, too!
Chocolate Brownie Cake
Since when does a cake have to be completely homemade for it to be something to brag about? Yes, this cake is made with both a boxed brownie mix and a boxed cake mix, but don’t let that fool you into thinking this cake is anything but decadent. It is one of my most popular cakes for a reason.
Ingredients
Chocolate Cake: Look for a box of chocolate cake mix. However, do not follow the box instructions; you will just use the mix.
Brownie Mix: As with the cake mix, you will only use the dry brownie mix in this recipe.
Ganache: This recipe makes plenty of ganache, so you may have a little left over. But, don’t let it go to waste; drizzle some over a bowl of vanilla ice cream for a sweet treat. I love the semi-sweet chocolate ganache but if you prefer milk chocolate, feel free to substitute.
How to Transport Cake
This is a great cake to make and bring along to share. Here are some tips to consider when transporting:
- Chill your cake before transport. I will place mine in the refrigerator overnight or in the freezer for a few hours before it goes in the car. A firm cake slides less and can handle more bumps and turns than a freshly baked cake does.
- Use a cake carrier. Just plan ahead if this is your chosen method of transport, as there is a certain height the cake needs to be to fit in the box. I have run into an issue with just a 2-layer cake that has piped dollops on top getting squished in a cake carrier. You can find extra tall cake carriers online if you know you love piping and decorating!
- Try a box for your cake, especially for long trips. My tips for that are to make sure the box is big enough, the box is lined with a shelf liner, and don’t forget about under the box! A great trick for that is a yoga mat right under the box.
- My favorite trick is to set the cake inside a springform pan. This works best for cakes that are on plates or platters. I get my 12-inch round springform pan, set the cake inside, and then set the springform pan on a shelf liner on a flat surface in my vehicle. (Usually, the back or the floor since seats are too curved). When you arrive at the event you simply carry in the springform pan then remove the outer edge! This has worked brilliantly more times than I can count.
Quick note: Cakes travel best in a cool environment, so bundle up extra if it’s a long car ride. If your interior temperature is too warm, the frosting could melt and slide down the cake. You can also place ice packs around the base of a box if you chose the box method.
How to Store Chocolate Brownie Cake
Cakes that are topped with ganache can be stored in a few different ways. It will last at room temperature for up to two days. Or, you can store it in the refrigerator for up to 5 days. And finally, if you want to save the cake for an extended time, it can be frozen for up to a month.

Made this with a red velvet cake mix during the holidays and it was gobbled up in a flash. How can something so simple be so delicious? Ty for this awesome recipe
@iambaker Can this amazing cake be made in a 13×9 baking pan? I’ve scrolled the comments and have seen this question before. But never a reply.
TIA
I have not made this in a 9×13 but others have commented they have.
I have made this cake in a 9×13 pan. I poke holes in the top before I pour the ganache on it. It turned out great!
Was wondering if i could make up the cake a day ahead and just make the gnache right before I serve?
Ingredients listed are vague. How much of each other than eggs?
Hi Kel!
Did you maybe miss the recipe card? All the ingredients are there. You may have scrolled right by with when looking for the comment area.

Can this recipe also be cooked into loaves? Thought about making several loaves of brownie cakes, but not sure if i should extend the cook time or make any changes to this tried & true recipe. Any help you can give, would be greatly appreciated!!!! It’s yummy for sure!
Hi Brenda – you can! It will depend on the size of your loaf pan as well as how many you use.
Thank you. I will try it as specified in your recipe. I’ll let you know how it turns out!!! I surely appreciate your response.
Can this cake be made in a springform pan instead of bundt? I need to put a “sweet 16” topper on which wouldn’t work in a bundt pan.
Did you adjust the amount of oil, eggs, and water? Or used the exact amount that was needed for both box mixes?
I.e. if the chocolate cake called for 3 eggs, and the brownies called for 2 eggs, did you add all 5?
Molly, her recipe has the exact ingredients. If you follow her recipe it is an awesome cake! Becky, I did make it using milk instead of water…just makes it even better!
Can I use milk instead of water
great recipe, fabulously beautiful on the buffet table. I will be making this cake again.
My husband claims this is the BEST chocolate cake he’s ever tasted
