Cake Mix Brownies
Delicious brownies made right from a simple box of cake mix!

Today, we have brownies!
Yes, you could just buy a box of brownie mix. But, imagine you have a brownie emergency and no way to get out to buy anything you need to make homemade brownies or brownie mix.
It could happen.
Ingredients List:
- Chocolate cake mix
- Egg
- Milk
- Oil
- Chocolate chips, optional
Chocolate Cake Mix: Any brand or chocolate variety will work. Just be sure to stick with a “standard” size box of cake mix. Anywhere from 15-18 oz is fine.
Oil: Stick with a neutral tasting oil. Canola, sunflower or vegetable will all work.

A few notes:
- This recipe is for an 8 x 8 baking pan, not the standard 9 x 13. Be sure to grease the pan well.
- Your batter is thick! I use a rubber spatula when spreading the batter with these. I also spray the spatula with non stick cooking spray. Makes the task a breeze!
- They are more on the cake-y side when it comes their texture.
Storage: Store any leftover over brownies in a covered container. You don’t need to refrigerate them, unless the weather is hot/humid in your area.
Can I Freeze These? Yes. Let them cool completely, then, cut into the desired slices. Store them in a freezer safe, covered container/storage bag. They will stay good for 2-4 months.

I love this recipe. It is my go to brownie recipe. This is better than brownie mix.
Thanks Faith! I agree..we love this at our house too 🙂
Can I use vegetable oil?
Yes, that will work fine. Enjoy!
I’m sorry I tried this recipe and it tastes like cake I don’t know why.
Hi Daniel- that’s ok! They are more of a cakey brownie than gooey. Thanks for the feedback 🙂
I love this recipe. They turned out perfectly delicious 🍫
So glad you liked them Bethany Joy! Thanks for letting me know!
I just made these brownies and used a smaller pan (7×7), and they were more of a gooey brownie! Not cake at all! Loved them this way!
Thanks for the feedback Jill! Glad you like them!
How can I make this recipe fudgy instead of cake like?
Hi Sheena! You could try adding a bit more oil to them. I haven’t tried that myself, but, if you do give it a try..please let me know how it works out! Hope you enjoy them 🙂
Am I the only one who struggled with the mix? I had a really hard time with this as the consistency was like sticky playdough and took forever to get out of my mixer. Might be worth it though. We’ll find out in 20 minutes.
Mine was very dry also – looked more like crumbles than a paste! I just added more milk until it got to the consistency where I could get the chocolate chips worked in.
Do i add water still or no
Hi Angelica- Nope, just what is listed in the ingredients list. Enjoy!
I used butter instead of oil and for the consistency to get it gooey like I added a little bit more milk came out perfect!
Great idea Tia..glad your liked them!

You are so welcome 🙂 Hope you enjoy them!
Will this recipe work with today’s cake mixes that are only 15.25 ounces? I clicked on the Pillsbury’s Purely Simple cake mix link, but it said the page couldn’t be found. I see, though, that as late as last summer someone had made this recipe, and I think cake mixes shrunk before then, so I’m hopeful.
Hi Vicki- Yes, stick with a standard size of cake mix and they should work out fine. Enjoy!
