Funfetti Brownies

Ever since I started making cakes from scratch, I don’t really enjoy cake mix based cakes as much. But I do love using cake mix for other purposes like cookies and even milkshakes. I’m always interested in discovering new uses for cake mix and recently was able to make some brownies using cake mix. Of course I had to use my brownie edge pan*.

I had some leftover funfetti cake mix so I decided to try a funfetti version. This brownie bakes up really fast. I was surprised to see it done within 15 minutes. The end result is something chewy and still a little fluffy. It looks like small slices of regular funfetti cake but it’s definitely denser and chewier, like brownie mix brownies. I enjoyed it though it was a little on the sweet side, but brownies usually are.

I found some different cake mix brownie recipes after making this one and will need to try those out and find out which one is best. I am happy to have found another use for cake mix though and my friends really enjoyed this one too. If you’re looking for other cake mix recipes, here’s what I’ve made so far:

You only need three ingredients for these funfetti brownies!


  • 1 box Funfetti cake mix minus 1 cup of cake mix

  • Preheat oven to 350°F. Grease a 9 x 13 inch pan. Mix everything in a large bowl until batter is smooth. The batter will be thick.

  1. TC and her friend really like that funfetti mix. They made it recently using those mini cupcake makers. The colors are attractive to them but I don’t really like the taste of that particular cake mix flavor.

    I like short cuts and have enjoyed the ease of making cookies in a pinch using boxed cake mix (ex: red velvet choc chip cookies).

    I’d like to try that Chocolate Coke cake recipe you have…

    • I like short cuts too and I like that you end up transforming the cake mix so it doesn’t just taste like cake mix. I actually like eating funfetti cake. Haha. It’s one of the few cake mixes where I’ll actually make cake from.

  2. what size cake mix did you use?? I have the Betty Crocker Party Rainbow Chip 15.25 oz box and wanted to use that to try this recipe.

  3. What could you do with the other 1 cup of cake mix so you don’t waste it?

  4. I wonder if I could I use devil’s food cake mix instead of funfetti.

  5. How many minutes will it last? 🙂

  6. Thank you so much for this. I do not remember the last time I baked a cake using a boxed mix. I just tend to not enjoy the out come. But because I do a lot of baking my mother in law tried to feed into my passion (also wanting to indulge in my sweets) so she bought multiple boxes of cake mix not knowing the cake she loves is made from sractch. I am going to try this brownie recipe with a strawberry cake mix I hope it turns out.

  7. Do you think i could make these in a 9×9 pan and just bake them longer for a thicker brownie?

    • i haven’t tried, so i dont know. i think it should work though there may be a danger of it getting cakey because of the thickness

  8. Followed this recipe to a T and it turned out so bad that I had to throw them out. Dry, tasteless, and crumbly. The frosting I covered it in couldn’t disguise it. Couldn’t give them to my friend for her birthday.

    • it sounds like you didnt follow the recipe to a T. perhaps you mismeasured something. Literally just two days ago, someone shared an instagram photo of the funfetti brownies they made from my recipe and were raving about them.

  9. Could I use 1/2 cup plain yogurt to substitute for the eggs. Was about to start making the brownies when i realized i had absolutely no eggs.

  10. If I wanted chocolate and was using yellow cake mix, how much cocoa powder would I use? Would I still use this same recipe?

    • Hmm, I haven’t tried it, so without testing it out, I can’t be sure. But I would imagine probably about 1/4 cup of unsweetened cocoa powder.

  11. Could I add 1/3 cup of milk?

  12. HI!! My roommate and I made this in our microwave and if you cut the recipe in half and put it in the microwave for about 3 mins it works great! However I will say we used coconut oil and applesauce because we didn’t have any eggs but I bet it would come out even better if you actually had all the ingredients!!
