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!

These turned out great! I used chocolate fudge cake mix. They turned out super fudgy in the center of the pan, with the right amount of crunchy bits around the edges. The top crisped up beautifully too. Tastes great later on in the day warmed up for 15 seconds. I would argue this is an excellent recipe for 2020 home days!
