Can I turn a box cake mix into brownies?
Oh yes, you definitely can turn a box cake mix into brownies! Cake mix brownies are probably one of the easiest ways to make a quick but impressive dessert.
I love shortcuts in cooking or baking and if I can use any type of box mix, I’m doing it! I love making a cake from scratch too, like my Chocolate Mayonnaise Cake, but I use box mixes for less mess!

Cake Mix Brownies
Cake mix brownies don’t last long enough in our house, but if they did, I’d serve them warm with a scoop of vanilla ice cream and maybe a little chocolate sauce drizzled over the top. Sound good? You can also add a little whipped topping.
Or just eat them by themselves, because they are delicious any way you choose.
How to Make Peanut Butter Brownies from a Cake Mix
Cake Mix Peanut Butter Brownie Recipe
There is no shame is baking with a cake mix! These Peanut Butter Brownies are chewy, delicious and will conquer your sweet tooth.
Ingredients
- 1 yellow cake mix
- 2 eggs
- 1/3 cup vegetable oil
- 1/2 cup peanut butter (smooth or chunky)
- 1 cup peanut butter chips (or chocolate)
- 1/2 cup peanuts or walnuts
- Preheat your oven to 350°
Instructions
- Using a hand held or Kitchen Aid Mixer, mix the cake mix, eggs and oil. Add and mix peanut butter. Stir in your nuts and chips. The mixture is thick!
- Pat the batter into a 9 x 9 inch pan. 9 x 13 can also be used if you want them a little thinner.
- Bake 14-17 minutes at 350° or until golden brown like in the photo. These need to sit for at least 20 minutes after cooking since they are soft and gooey. Cut yourself a piece and enjoy!
Notes
This recipe has a lot of flexibility. If you don't have a yellow cake mix, try another flavor. You can omit the nuts if needed. You can use any flavor chips you enjoy. Heck you can even use whatever nut butter you choose.

Making this for a cookie table and the first 2 batches have come out dry. Any suggestions?
Kim says
Hi Suzy, I had emailed you separately when I saw this comment come through. We had discussed adding a bit more oil and that seemed to do the trick. Also, for others reading, make sure the peanut butter you’re using isn’t dry. Some brands that you have to stir the oil into can be dry if the oil isn’t fully incorporated. I’m glad your next batch came out great!
Sue Thomas says
On the cake mix brownies do you use a cake mix and a peanut butter brownie mix in the recipe too? Or is it just the cake mix? Please let me know because I plan on making them today. Thanks Sue
Kim says
Thanks Sue, it looks like the recipe card updated with a glitch. Use just the cake mix. Thank you for pointing this out. It’s fixed.
Sheila says
I made these yesterday and although the taste was excellent mine were very dry also. How much extra oil should be added.
Kim says
That is interesting. I wonder if it’s the difference in peanut butter brands. I would probably add a tablespoon of vegetable oil if needed.
Art Watanabe says
Hello Kim
I had a question on one of the ingredients. For the Vegetable Oil, is that 1/3 cup?
Thank you
Kim says
Thank you! Yes, it’s 1/3 cup. I thought I fixed that. Thank you for letting me know.
