How to make brownies from cake mix

First, you’ll need a box of your favorite chocolate cake mix.

For this recipe, I used Duncan Hines Dark Chocolate Fudge, but any chocolate cake mix will work.

Add the cake mix, olive oil, eggs, vanilla extract, and chocolate chips to a large bowl.

Use a rubber spatula or spoon to mix until completely combined.

Smush it down into the edges, and flatten out any lumps.

Bake at 350 degrees until done, around 20 – 25 minutes!

Allow to cool completely before cutting for easiest results.

If you’re like me, this is pretty much impossible!

I made these and used a mix of leftover Halloween candy in place of the chocolate chips! They were delicious!!

i tried this again with another betty crocker mix, this one was butter pecan, but i adjusted the oil from 1/2 cup to 2/3 cup and it turned out perfect.

I found your recipe last week and have made it 4 times since then!!! OMG I love baking from scratch and felt a little guilty taking a short cut but am so glad I did!. Thank you for this recipe. I was wondering if you have ever lightened this recipe up with applesauce or bananas and if so how much? If I am going to make these often I figure I should at least try to see if I can lighten in up LOL

@Joy Shull, I used 1/4 cup melted butter plus 1/4 cup applesauce in place of the oil. It was fantastic!

Typically you can replace the oil with an equal amount of applesauce. I have not tried it with brownies though. Keep me posted how it turns out!

Thank you for this recipe I followed it for making strawberry and lemon bars from box mixes and they came out perfectly! Now I can turn anything into a brownie texture, hooray!

@AnonyBaker, I love those flavors! Did you just follow this recipe exactly and used the different flavor cake mix? Did you omit the chocolate chips? Thank you in advance! I am eager to try it!

Just so happens I have a Duncan Hines Dark Chocolate Fudge cake mix, eggs, vanilla, olive oil, and a partially eaten (who did that!?) large bag of chocolate chips, with enough left for the recipe. And most importantly, I also have a hankering for brownies. Sounds like a perfect match, doesn't it?

Thanks for the recipe!
