How to make brownies from cake mix

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

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. 

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

Spray an 8 X 8 baking dish with cooking spray, then add the batter in.

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 have been known to ruin batches of brownies because I just couldn’t wait to dig in and try one. 

Share these at a party, with your friends and neighbors, or just make it for yourself when you deserve a treat.

Hi. I'm making this recipe tomorrow and realized I picked up a box of chocolate fudge cake mix instead of DARK chocolate fudge. Do you think it will make much of a difference? I can cook, but I am not a baker, so this is perfect for me. Thank you for posting!

This is so great! I’m definitely more of a brownie the cake fan, but brownie mix is over double the price of cake mix

Tried this tonight using a yellow cake mix, white chocolate chips and pecans... Amazing!!! Gooey in the inside and crunchy on the outside. Served warm with vanilla ice cream and caramel drizzle. Definitely a hit with my husband. Thank you!!
