how to make brownies out of cake mix

Knowing how to make brownies out of cake mix comes in handy. We’re suckers for something sweet after dinner. One of our favorite boxed cake mix recipes. (participates in the amazon program, affiliate links present, originally published 3/17)

We’ve made peanut butter brownie in a mug, peanut butter cookie brownies, homemade brownies, and now these.

If you’ve never made anything other than a cake right out of the box there is actually a lot you can do with cake mix.

  • You can use the peanut butter version above, or the strawberry one down below.

We’ve made donuts too which I will share below. There’s an easy way to make just a portion of the box so you don’t have to make all 24 cupcakes either.

Varying the ingredients is the only difference between a sheet cake, a few cupcakes, donuts, or making these brownies with cake mix here.

It’s texture really. You want brownies to be dense, chewy, and thicker than a cake.

  • We made strawberry brownies this time but it really works for any flavor cake mix you choose.

You only need 3 ingredients to transform any cake mix into brownies and I am sure you have them all at home.

From there you can add things like nuts, frosting on the top when they’re cooled, or even chocolate chips if you want to load them up.

  • A box won’t make a 9×12″ pan full like it will if you make a cake as directed.

Rather it will fill a square 8×8 pan or so and come out the thickness you see here.

They are quite rich and sweet so half of one of these pieces is quite enough to satisfy my sweet tooth.

It’s is an easy brownie recipe if you don’t have the time to make any from scratch or a box of ready made in your house.

Cake Mix Brownies

  1. Cake mix
    1. we used strawberry but you can choose your flavor of choice
    2. chocolate cake mix is great too for devils food brownies
    3. yellow cake mix turns out more like blondies
    4. there is gluten free boxes of cake mix available too
  2. Oil
  3. Eggs
  4. Parchment paper – helpful to lift them out and cut them
  5. A square 8×8 baking dish
    1. non stick cooking spray is very helpful
  6. Large bowl
perfect brownies

If you love chocolate brownies try this with devil’s food cake mix and add some finely chopped nuts if you like. They are quite good and definitely satisfy a sweets craving if you need something quick!

  • TIP to making really soft and chewy brownies = do NOT overbake them! Make sure you take them out when the outside rim is light brown and the center is not wet but looks underdone.
  • The same is true if you’re using our air fryer brownies method of cooking too.
  • Allow them to cool completely in the baking dish after that before slicing for perfection.

Cake Mix Recipes

  1. 2 ingredient strawberry cake is seriously the best ever
  2. You can make chocolate chip cookies made with cake mix or pumpkin cookies with cake mix that are fast treats

We have a bunch of other great angel food cake mix recipes here to try as well.

Of course oven temperatures vary slightly and altitude will change the cook time a bit.

Bake for 17 – 20 minutes would be minimum so I would start with that. 21 minutes works for us but we’re in the mountains.

How do you store brownies for the next day?

Brownies can actually taste better the next day! Completely cool in the pan, do not cut them, cover the pan with foil, refrigerate.

If you want to freeze them wrap uncut brownie in 2 layers of foil, and 1 layer of plastic wrap. Freeze the batch for up to 4 months.

Can I leave my brownies out overnight?

Yep! You can definitely leave them out at room temperature. Stored in airtight bags or containers, they will stay nice and fresh for about 3-4 days on the countertop.

That has happened to me when I have cooked them too long. You need to ignore your instincts and take them out your brain is telling you they still need a few more minutes. Otherwise, just like you said: dense cake texture, not brownie texture.

Do you mean use 2 eggs total or add 2 eggs to the eggs already called for in the recipe?


Monday 9th of November 2020

Only 2 eggs in total

I r made these strawberry ones several times! Make a glaze to pour over top with powdered sugar and milk. I e added white chocolate chips. At Easter I did strawberry and also did with a lemon cake mix and an orange cake mix! Put the white chocolate chips in all of f them and the glaze . They were pretty and pastel for spring.

2 boxes of cheesecake flavored pudding mix, 6 eggs, 2 boxes yellow cake mix, 1 stick melted butter or margarine, a dash more oil if you think it's too dry, 1 bag chocolate chips or mini chocolate chips. I mix the eggs and butter together first, and pour it over the dry ingredients. I baked it 17 as on here, was too goopy, so I put it back in for 7 more. Still too goopy, So 5 more. I stopped at that point. Should have baked another 5 maybe or 10. Idk if I could have done something differently or baked at a higher temp. Just got sick of baking and said good enough. Haha.
