Chocolate cake mix: You’ll obviously need a chocolate cake mix for these cake mix brownies. My favorite brands for cake mixes are Betty Crocker and Duncan Hines.

For these brownies, I used a Betty Crocker dark chocolate cake mix.

Vegetable oil and butter: This recipe calls for both oil and butter. I love butter for the flavor and oil because it adds moisture.

Vanilla extract: Adding vanilla extract to anything you’re baking, especially if it’s a cake mix based recipe, really helps give it that homemade taste.

Mini chocolate chips: Adding these to the brownie batter and sprinkling on top, just raises the level of chocolaty goodness.

Tips & FAQs:

How do you turn a chocolate cake mix into brownies?

It’s very easy and quick to make brownies out of a cake mix. For this recipe, you’ll use a dry chocolate cake mix and add in just a few extra ingredients to it, then spread into an 8×8 inch pan and bake.

What brand of cake mix should I use?

You can most likely use any brand, but I used Betty Crocker dark chocolate cake mix.

Should I prepare the cake mix by adding in the other ingredients listed on the cake mix box or just use the mix dry?

No, you want to use the cake mix dry. Do not add the other ingredients called for on the back of the box.

Do I have to add the mini chocolate chips? Can I use regular chocolate chips instead?

The chocolate chips are optional and you can add regular chocolate chips instead if that’s what you have.

Important baking tip:

Be very careful not to overbake these brownies as they can dry out quickly if overbaked even a little.

How should these brownies be stored and how long do they last?

Cover these brownies well and store at room temperature for up to 5 days.

What’s the best way to eat/serve these brownies?

These brownies are best served at room temperature or warmed up. You can really go over the top by warming up a brownie or two and topping with ice cream. Yum!

What can be added to these brownies?

I love adding mini chocolate chips to these brownies, but you could also add in any flavor of chocolate chips like white chocolate, etc. You could also add in peanut butter chips or butterscotch chips. Feel free to also add in nuts like chopped peanuts or walnuts.

How to tell when these brownies are done?

Pull these brownies out of the oven when the baking time is up. Be careful not to overbake as that will dry them out. These brownies will still feel a little jiggly in the middle when they’re pulled out of the oven but will firm up as they cool. Also note that as they cool, the brownies will sink down in the middle, which is normal.

Ingredients

  • 1 15 oz box chocolate cake mix (I used Betty Crocker Dark Chocolate, but any chocolate cake mix will do)
  • 1/3 cup vegetable oil
  • 3 tablespoons melted butter
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1 cup mini semi sweet chocolate chips (optional)

Instructions

  • Preheat the oven to 350 degrees F and spray or grease an 8×8 inch pan. (If you want to use a 9×13 inch pan, double the recipe.)
  • Add the cake mix, oil, melted butter, eggs and vanilla extract to a large bowl. Mix well with a wooden spoon or a silicone spatula until well combined.
  • Add 1/2 cup of the mini chocolate chips and mix with a spoon.
  • Add the batter to the prepared pan and spread evenly. Sprinkle on the remaining 1/2 cup of mini chocolate chips.
  • Bake the brownies at 350 degrees for approximately 25 minutes. Pull these brownies out of the oven when the baking time is up. Be careful not to overbake as that will dry them out. These brownies will still feel a little jiggly in the middle when they're pulled out of the oven, but will firm up as they cool.
  • Once baked, take the brownies out of the oven and set the pan on a cooling rack to cool completely. As they cool, the brownies will sink down in the middle, which is normal. Make sure to let them cool completely before cutting.
