How To Make Brownie Mix

To make a homemade brownie mix, you’ll need a large bowl and whisk and the following ingredients. I like to double or triple the batch so I have brownie mix on hand. 

  • All-purpose flour
  • White sugar
  • Cocoa powder (I like to use dutch process, but I’ve also used regular and they turn out great too)
  • Baking powder
  • Salt

Dump all the ingredients into a bowl, whisk together well and store in a jar or tightly covered container. Tada! Homemade brownie mix couldn’t be easier.

How to make brownies from brownie mix?

Now, when you want a batch of brownies, measure out 3 and ¾ cups of brownie mix and dump in a large bowl. (That’s one batch as written below.)

Add 4 room temperature eggs and 1 cup melted butter to the brownie mix, plus 1 teaspoon vanilla extract if desired. Stir well. Pour into a greased 9×13-inch pan and bake at 350°F. 

If you prefer a smaller batch of brownies in an 8×8-inch pan, you can make a half recipe. Just use 1 ¾ cups plus 2 tablespoons of brownie mix plus 2 eggs and ½ cup melted butter.

Can I substitute butter for oil in brownie mix? 

Oil and butter can be used interchangeably in brownies. I like using melted butter best because it gives a great flavor.

Vegetable oil is admittedly easier to use since you don’t have to mess with melting it. Oil will also provide some additional moisture since oil coats the proteins of the flour and butter soaks in. 

In the past, I’ve used half butter and half oil for my brownies in order to get both the buttery flavor and more moisture too.

What else can I use homemade brownie mix for? 

Besides making a traditional pan of brownies when the craving hits, you can also use the box mix to make fancy brownies. I like to double or triple the batch so I have mix on hand for several batches of brownies at a time.

Homemade brownie mix is a great DIY pantry staple. Simply add some mint extract and use a pan of brownies as a base to my Mint Brownies with Chocolate Ganache.

You can also add chocolate chips, nuts, peanut butter cups, crushed Oreos, or whatever add-ins your heart desires to take these brownies up a notch.

    I absolutely love this recipe! I never knew having a quick and easy brownie mix that is pre-made and set aside ready to go would become so useful!

  2. Chrishawn Green says

    Used oil in replace of butter… batter was super thick and wouldn’t even pour into the pan. Had to pay them into the pan. Only baked them 25 minutes and they’re dry and crumbly. Somethings not right in the recipe…

  3. Cicely S says

    Help! I want to make this recipe and I’m hoping to use it as gifts, but should I bake with 2 eggs or 4? Ingredients list states 4 and prep instructions says 2. Thank you for clarifying. 😊

  4. Montana Rooks says

    Used measurements for 8×8 pan. 1 egg, 1/2 vegetable oil. It seems too chunky. Usually box brownies you can pour. This is thick; almost solid. Is this right?

      • Kristin Sponsler says

        The recipe still isn’t updated. So is it 4 eggs for the whole batch? And add more oil? Also it says 1 batch is 3 3/4 cups of dry mix but the dry ingredients listed add up to 4 cups. So do you use all but 1/4 cup of the mix? Confusing.

        • Mary says

          You’ll use 4 eggs for the recipe as written for a 9×13 pan of brownies. Once you’ve stirred all the dry ingredients together, the flour will be a tiny bit more compacted and it typically adds up to 3 3/4 cups total. I’ve written it this way to avoid confusion. (But clearly it isn’t working – sorry about that!) I’ve done my best to clarify it above. Let me know if you still have questions.

    Hello, I was wondering if I could add some cookie dough/homemade cookie dough to the pan with the brownie mix while it bakes. I was hoping it could turn out to be a brownie/cookie brownies. Let me know if this is possible
