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

Allow them 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.

I made this recipe yesterday with these changes: I used sugar free cake mix. I couldn't find sugar free chocolate chips at the store, so I excluded the chocolate chips, but I chopped up a bunch of walnuts instead. Cooking time and everything else is the same. They were wonderful and very yummy! I will do this again and again.

@Selena, thanks. I'm using the sugar free cake mix as well. It still has carbs but less. I'm using pecans. It seems like a versatile recipe.

Made these this morning with Red Velvet cake mix. I took 1/2 cup of the cake mix and added 1/2 brick cream cheese to that. Dollaped on top and baked. Yummy
