This recipe for cake mix brownies has a super short ingredient list. Just 4 simple ingredients is all you need! How awesome is that?!

  • Chocolate cake mix. You’ll need a 15.25 ounce box of chocolate cake mix. My go-to brand for this recipe is Duncan Hines Triple Chocolate. Betty Crocker works great too.
  • Oil. Either olive or vegetable oil will yield brownies with the perfect moist texture.
  • Eggs. Two eggs will add structure, stability, and richness.
  • Chocolate chips. For best results, I recommend splurging on a quality brand. I always use Ghirardelli chocolate chips. We love semi-sweet chocolate chips in these brownies, but feel free to use any favorite baking chips.

how to make this recipe

Turning cake mix into brownies is incredibly easy! Here’s how:

  • Prepare oven and baking pan. Preheat your oven to 350ºF. Spray an 8×8-inch baking pan or dish with nonstick cooking spray or line it with parchment paper.
  • Combine all ingredients. In one large bowl, stir all of the ingredients together.
  • Bake. Transfer the batter to the prepared baking pan and evenly smooth out the top. Sprinkle chocolate chips over the top for a little extra chocolate goodness. Bake for 20 to 25 minutes. The brownies should feel set on the edges, and a toothpick inserted into the center should come out mostly clean. I know some people enjoy their brownies undercooked, so feel free to remove these brownies a little early.
  • Cool and serve. Let the brownies cool in the pan (on a wire rack) for about 10 minutes, then cut into squares and enjoy! Delicious with a scoop of vanilla ice cream!

expert tips

This brownie recipe could not be easier, but here are a few tips to make sure your brownies turn out perfect every time.

  • Pan size. Be sure that you use an 8×8-inch baking dish or pan for this brownie recipe. Many cake mix brownie recipes use a 9×13-inch pan, like my chocolate chip brownie bars, but this one turns out best using a smaller pan.
  • Spreading batter. It is normal for this brownie batter to be very thick. Grease your baking dish well or line it with parchment paper. I use a rubber spatula that has been sprayed with nonstick cooking spray to spread the batter. Makes this step a cinch!
  • Pan type. Either a metal or glass pan will work fine for baking brownies. For crispier crusts and edges, use a metal pan. If you use a glass dish, you may need to add up to 5 minutes of baking time, but be sure to check on your brownies at the time suggested.


You can use your favorite flavor of cake mix to create any type of delicious brownies with just a few ingredients. Here’s some of my favorite ideas:

  • Red velvet. Make these cake mix brownies red velvet flavored by using a red velvet cake mix.
  • German chocolate with caramel. Add a little decadence to your brownies.
  • Yellow cake mix. A super easy way to make blondies! Or use a strawberry cake mix to make strawberry blondies!
  • Nuts. Finely chopped nuts, like pecans or walnuts, can easily be added to this recipe. I recommend 1/2 to 2/3rds cup of chopped nuts. You can simply sprinkle them over the top or stir them into the batter.
  • With cream cheese. Add a swirl of softened or whipped cream cheese over the top.
  • Candy. M&M’s, Reece’s Pieces, peanut butter chips, or toffee bits are fun additions.

frequently asked questions

Is brownie mix the same as cake mix?

Brownie mix is just a cake mix without any leavening agent. So, with a little added baking powder and oil or butter, you could turn your fudgy brownies into a chocolate cake!

What makes brownies fudgy vs cakey?

Fudgy brownies have a higher fat-to-flour ratio than cakey ones. So add more fat, in this case, we’re adding more oil and chocolate. A cakey batch has more flour and relies on baking powder for leavening. The amount of sugar and eggs does not change whether you’re going fudgy or cakey.

What else can be made from cake mix?

how to store

Leftovers are best stored in an airtight container for 4-5 days, but I would be very surprised if they last that long.


To freeze, cool completely then transfer them to an airtight container or freezer bag and freeze for up to 3 months. When ready to serve, thaw at room temperature. I can attest to the fact that these are possibly even better once frozen and then microwaved (think melty chocolate chips and rich, fudgy center).
