Yep, I’m baking again! I have a good excuse this time and it’s not just to eat the goodies. It was my mother-in-law’s birthday this weekend and I just had to make her “my special birthday cake”. I’m a big believer that everyone should have cake on their birthday. Adults get my special “Ultimate Death by Chocolate Brownie Cake” and my kids get a homemade cake of their choice. My 7 year old asked for a Justin Bieber cake or a puppy cake this year, and since I can’t let her get caught up in “Bieber-fever” this early, she got an adorable puppy cake!

So, back to the reason for this post – the Ultimate Death by Chocolate Brownie Cake!  I have been making this cake for family members (and friends!) for over 15 years and this is the first time I’m sharing it!  It’s so easy to make but so sinfully delicious that people ask for it year after year. And don’t get me wrong, this is NOT just a birthday cake. This is a cake for anytime or anywhere! No matter what the holiday, occasion or just ordinary day, you can fit in this cake. I’m sure you gathered from the name of the cake that it’s all chocolate!  If you are a chocolate-lover (and if you aren’t I’m not sure we can be friends!), you will love this cake. It will satisfy any chocolate fix you have. It’s chocolate cake, brownie, chocolate frosting and chocolate chips all combined to make a masterpiece!

Ultimate Death by Chocolate Brownie Cake




  • Chocolate Cake Mix (any chocolate flavor)
  • Brownie Mix (13×9 Family Size)
  • 2 cans of chocolate frosting (any chocolate flavor – dark, milk, fudge…etc)
  • 5 eggs (for the cake and brownie mix)
  • Veg oil (for the mixes)
  • One 12oz package of Nestle Semi-Sweet Chocolate Chips
  • Two (or three) 8″ round pans

Make the Cake & the Brownie:

1. Make the chocolate cake according to the box. Pour batter evenly into two lightly greased 8″ round pans and bake at 350 degrees for 32-37 minutes. Cake is done when toothpick inserted in center comes out clean. Cool in pan for 10 minutes before transferring to a plate to cool completely.

2. Make the brownie mix according to the package. Pour entire brownie batter into one (1) lightly greased 8″ round pan. Make sure the brownie pan is the same size as the cake pans that you used!  Bake the brownie at 350 degrees for 25-27 minutes. Watch the brownies carefully as not to overcook them but make sure they aren’t completely doughy in the center.Cool in pan for 15 minutes before transferring to a plate to cool completely. I found it was easiest to remove the brownie carefully using a wide spatula underneath.

Assemble the Cake:

3. Pick the plate you want the cake to be displayed on and start with one (1) cake layer. Frost the top of the cake layer with about 1/3 of one of the frosting containers. Sprinkle a handful of chocolate chips on that layer. (Note: Any chopped up candy – Reese’s, M&Ms, Heath Bits etc can be substituted for the chocolate chips to add another flavor!) Carefully place the brownie layer on top of the cake layer.

4. Frost the top of the brownie layer with about 1/3 of one of the frosting containers. Sprinkle a handful of chocolate chips on that layer. Carefully place the 2nd cake layer on top of the brownie layer. Carefully frost the top of the cake with the remaining 1/3 of the frosting container.

5. Spread the entire 2nd container of frosting on the sides and top of the cake. BEFORE THE FROSTING SETS, you need to apply the chocolate chips to the outside. Take a handful of chocolate chips at a time and firmly press against the side of the cake until most of the chips stick. Some chips will fall to the plate and you will use those to fill in the holes.

6. Repeat this process around the entire cake. Take the fallen chips and the chips that you have left and fill in the holes and sprinkle on top.

7. That’s it!  You will be the hit of the birthday, holiday or occasion!!  Enjoy! Look at the inside brownie layer!!!  To Die For!!!

    Suggestion: Try chocolate fudge pudding for the filling – use half the milk in directions to make it firmer to spread – and, of course, keep the chocolate chips. You can even bake the cake with the chocolate chips in it – sometimes, they will fall to the bottom of the cake pa. Makes entire cake more moist and more chocolatey.

    Made this cake last night to celebrate my fiances birthday tonight…have yet to try it but looks amazing. I used chopped up Reese cups instead of chocolate chips to add another flavor other than rue chocolate. Will let you know how it goes over with everyone!

    Just made this cake tonight. I too had to bake the brownies for about 40 minutes; I think it might be because I chose fudgy ones, rather than cake-like ones. Amazing recipe!

    When I saw this on Pinterest, I knew I had to try it! Thanks for sharing it! Just made it for a get-together tonight. No doubt, it will go over with all the chocolate-lovers there! I did have to bake the brownie layer longer, probably about 40-45 minutes before the center was done. And not being a fan of ready-made frosting, I made chocolate buttercream frosting, and it took 3 batches of the recipe to cover the cake. Wow! Can’t wait to try this cake!!

    Just made your cake for my family. 18 people were here for my hubby’s birthday and everyone loved it. I even have half a cake left over because it is so filling, one small piece is all we could do. Thanks for sharing your idea. I saw it on pinterest. I will have to try some of your other posts!

    Just saw this on Pinterest and HAD to come check it out. Looks insane. I am not sure when I will be able to make this (a pretty serious diet started this week) but I will have to dream up a special occasion soon. Unless you want to mail some to me…?
