🍴 Recipe Tips
Making these brownies from devils food cake mix is incredibly easy and quite fun to do. Simply mix together the ingredients and pour them into a pan. Simple.
That said, you should keep in mind that you do not want to overmix the batter. Overmixing your brownie batter will lead to a much more crumbly texture and not the soft fudgy ones we are looking for. So only mix until you have gotten no flour streaks remaining.
You can add in 1-2 cups of chocolate chips if desired for an even stronger chocolate flavor.
