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!

Hiiiiii! I just made this recipe, i felt kinda weird tho bc i usually make from scratch but bc i couldn't find cocoa powder (which i swear i just bought!) i tried this, I used choco-chunks and added an extra handful then sprinkled more on top(im a chocolate addict as you an see), and added a lil milk too I followed the rest of the instructions other than that. Exactly 25 mins 350 degrees worked perfect! And OMG it came out AMAZING!!!! super moist and chocolaty i 100% recommend letting cool for about 10 min! thx for the recipe!

Hi! I am still obsessed with this recipe! Lol I've tried it with strawberry cake mix and white choc chips. It was a hit! Also, I used a small cookie scoop and put in mini muffin pans. Baked at 350 for 8-10 min and it makes them into mini brownie bites!! QUESTION- best way to store these and for how long? Thanks in advance!

Allow to cool, is the operative task here. Too soon and you seem to get what appears to be undercooked mess. Fresh out of the oven could be a topping for ice cream though...

Mixing this batter is a workout in itself....
