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.

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!

Does this recipe work with sugar free cake mix?

I have not tried it myself.

1 Tablespoon of vanilla (as stated in the recipe) sounded like too much. I added 1 teaspoon and still feel like it’s too much. Anyone else notice this?

You are certainly welcome to use less or no vanilla if you are sensitive to it. I personally can't taste it at all in this recipe.

I haven't put them in the oven yet but they do look like chocolate concrete. Is this ok or have I done something wrong?

The batter is thick, you can reference the pictures in the post of the batter being spread into the pan to see.

Ummmmmmm these cake brownies are so good! This is my ideal brownie format - most brownies I've tried to make end up too heavy for my taste. I followed the instructions but added some mini marshmallows with the chocolate chips and used the Betty Crocker triple fudge cake mix and they turned out fluffy, but somehow still gooey, chewy and crispy along the edges. Yum!! All I have to say is - she mentioned letting it cool completely - that part is pretty important because I couldn't wait and I took it out of the pan and it kinda fell apart...but it's not a huge deal because I can still cut it into brownie bites and it will still be amazing. New favorite brownie recipe, thanks!!

Made 2 batches for Game Day! One with 1/2 bag of Peanut Butter chips, for the "Reese's" fans, and one with 1/2 bag of Caramel chips, for the "Turtles" fans. Baked 22-min in 8x8 pan. They turned out GREAT!!
