Easy Homemade Brownie Recipe

Raise your hand if sometimes you reach for a box of brownies instead of making them from scratch. I know that I definitely have – sometimes it’s just so much easier! Now I just make these Cocoa Powder Brownies instead!

I created this recipe with the intention for it to be quicker and easier to make, and to mimic a boxed brownie mix. In a boxed brownie mix, you’d typically add oil, water and eggs. This recipe is the same, but instead of water, I added some milk for richness.

While most homemade brownie recipes do not usually have a leveling agent, I intentionally added one to this recipe. The baking soda prevents the brownies from being overly dense and fudgy, though they’re definitely not cakey either. It’s the perfect middle ground! (And some boxed brownie mixes, like our favorite Ghirardelli Double Chocolate, also contain baking soda.)

What’s the Difference Between These and Fudgy Brownies?

I’ve shared a handful of brownie recipes in the past, most of them variations on my fudgy brownies recipe. So what makes this recipe different?

  • This recipe is quicker and easier to prepare with less dishes
  • These are thinner, less dense and a litte less rich
  • There’s no melted chocolate in this batter. The melted chocolate makes for a heavier, denser and fudgier brownie
  • These chewy but still fudgy brownies are my version of our favorite boxed brownie mix.
  • This recipe used oil instead of butter, which keeps them moist

Key Ingredients

Here are the main ingredients you’ll need for these homemade brownies. Scroll down to the recipe card to see the exact measurements and full ingredient list.

  • Granulated sugar
  • Oil – Vegetable oil helps keep the brownies moist. I don’t recommend substituting melted butter.
  • Milk – Adds a richness to the brownies.
  • All-purpose flour
  • Cocoa powder – It’s important to use natural, unsweetened cocoa powder. See notes below.
  • Baking soda – A touch of baking soda provides just enough air pockets in these brownies to mimic a boxed brownie mix.
  • Semi-sweet chocolate chips – Add that rich, chocolatey goodness.
  • Flakey sea salt – Optional but I love the salty-sweet combo.

A Note On The Cocoa Powder

The key to making these brownies is to use natural cocoa powder, NOT dutch processed cocoa powder. (Learn more about the difference between the two here.) The reason for this is the baking soda in the recipe.

Baking soda requires an acidic ingredient to activate it in a recipe. Otherwise, you end up with a flat dessert and a metallic aftertaste. In the case of this brownie recipe, natural cocoa powder is the acidic ingredient.

If you use dutch processed cocoa, which is made from beans that have been treated with potassium carbonate, the baking soda will not activate and these brownies will not only not rise, they will have a not-so-pleasant aftertaste.

How to Make Cocoa Powder Brownies

This may be the easiest brownie recipe out there – it comes together in just a few quick steps!

Step 1: Combine the wet ingredients. Beat the granulated sugar with the oil, milk, and vanilla extract. Add the egg. Take care not to overbeat the eggs, beat just until combined.

Step 2: Add the dry ingredients. Combine the dry ingredients in a separate bowl. Add to the batter until just combined. Fold in the chocolate chips.

Bake. Transfer the batter to the greased baking sheet lined with parchment paper. Add some extra chocolate chips on top. Bake for 18 to 22 minutes then cool before cutting.

Can I Make These in a Different Sized Pan?

I recommend an 8-inch square pan for the perfect thickness, but if you only have a 9-inch pan, that will work too. The brownies will just be much thinner and you’ll need to reduce the baking time by a few minutes.

This recipe can easily be doubled for a 9×13 inch pan.

Tips for Success

Here are a few tips for making the best cocoa powder brownies – which may be different from what you would do for regular brownies.

  • Don’t overbeat the batter once the egg has been added. Typically a well-beaten egg will help to create the meringue or flakey layer you traditionally find on the top of brownies. However, since this has baking soda, overbeating the eggs will cause the brownies to puff up too much in the centers and then sink as they cool. You’ll still get a thin crisp layer on top that cracks when you cut it.
  • How to easily cut brownies. For clean-cut brownies, wash and dry the knife after each cut.
  • Can I Use Butter Instead of Oil? While butter is an acceptable substitute for oil in brownies, I found that with the melted butter, these brownies came our drier than the oil version.
  • Don’t overbake. A toothpick inserted in the middle should still come out damp, though not gooey or wet.
  • Add sea salt. I love a touch of flakey sea salt on top to finish these off. It helps cut the sweetness and salty sweet is my favorite combo.

Serving Suggestions

I don’t believe there’s a wrong way to enjoy a brownie…but I will say that since these aren’t quite as dense and rich as fudgy brownies, they are perfect for making an ice cream sundae! Just add a scoop of vanilla ice cream, some chocolate syrup, and a maraschino cherry. Yum!

Or just enjoy with a glass of milk. (Bonus points if the brownie is warm.)

How to Store & Freeze

These homemade brownies will last for up to 3 days when stored on the counter in an airtight container. If you want them for a few extra days, store them in the fridge where they’ll last for up to 5 days.

To freeze the brownies, I recommend wrapping each one individually in plastic wrap. You can thaw in the fridge, on the counter, or pop them in the microwave for 15-30 seconds for warm brownies.

    What did I do wrong? Followed the instructions but my brownies are really gooey! I mean, there’s nothing wrong with that but…

    I baked them a little longer and the toothpick is still coming out gooey.

      Hi Meaghan, you just need to keep baking them until they bake all the way through. The toothpick is still gooey but not wet. All ovens and pans will bake differently and it’s possible the oven is not 100% accurate on the internal temp.

    Question? I know you like to use dark chocolate cocoa powder for your cakes does that apply to this brownie recipe as well or should I just use the regular cocoa powder?
