To make brownies with cocoa powder, whisk ½ cup (113 g) melted butter with 1 cup (200 g) sugar, beat in 2 eggs and vanilla, then stir in ½ cup (43 g) unsweetened cocoa powder and a pinch of salt, and fold in ½ cup (60 g) flour. Bake in an 8×8-inch pan at 350°F (175°C) for 20 to 25 minutes, until a toothpick shows a few moist crumbs.
No melted chocolate or mixer is needed: it is an easy one-bowl brownie recipe that takes about 10 minutes to mix.
There is a quiet argument in every family about brownies, and it comes down to one word: fudgy or cakey. This recipe takes a side. It uses cocoa powder instead of a chocolate bar, which sounds like a shortcut and is actually the secret, because cocoa brings all the chocolate flavor with none of the bar’s extra fat and sugar, so the butter and the eggs decide the texture. Three small things settle whether the pan comes out dense and glossy or dry and bready: how hard you beat the eggs, how little you stir after the flour, and when you take it out of the oven. Everything else is forgiving.
How do you make fudgy brownies with cocoa powder?
Makes: 16 squares (8×8-inch / 20×20 cm pan) · Prep: 10 minutes · Bake: 20–25 minutes · Total: 35 minutes plus cooling
Ingredients
- ½ cup (113 g) unsalted butter, melted and slightly cooled
- 1 cup (200 g) granulated sugar
- 2 large eggs
- 1 tsp (5 ml) vanilla extract
- ½ cup (43 g) unsweetened cocoa powder
- ¼ tsp (1.5 g) fine salt
- ½ cup (60 g) all-purpose flour
- Optional: ½ cup (85 g) chocolate chips or (60 g) chopped walnuts
Instructions
- Prepare the pan. Heat the oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) pan with parchment, leaving an overhang on two sides.
- Whisk butter and sugar. Whisk the melted butter and sugar until combined. Add the eggs and vanilla and whisk vigorously for a full minute, until thick and glossy.
- Add the cocoa. Sift the cocoa powder and salt into the bowl and stir until completely smooth.
- Fold in the flour. Add the flour and fold with a spatula just until no dry streaks remain. Fold in chips or nuts, if using.
- Bake. Spread the batter evenly and bake 20–25 minutes, until the top is set and a toothpick inserted in the center comes out with a few moist crumbs, not wet batter.
- Cool, then cut. Let the brownies cool completely in the pan, lift them out by the parchment and cut into 16 squares.
How much cocoa powder do brownies need?
For an 8×8-inch pan, half a cup (43 g) of unsweetened cocoa gives a rich but balanced brownie. Going up to two thirds of a cup (57 g) makes them darker and more bitter, and if you do, add one or two tablespoons more sugar to keep the balance. Measure by spooning cocoa into the cup and leveling it, never by scooping, which packs the cup and is the most common reason cocoa brownies come out dry.
Why use cocoa powder instead of a chocolate bar?
Because of what each one brings. Cocoa powder is cocoa solids with most of the fat pressed out and no sugar, so it delivers concentrated chocolate flavor and leaves the butter to set the texture, which is how you get a dense, fudgy crumb and a sweetness you control. A melted bar brings cocoa solids plus cocoa butter and usually sugar, so the texture is softer and partly fixed by whoever made the bar, and the chocolate flavor per gram is diluted by its own fat and sugar. If a recipe you love uses unsweetened chocolate and you only have cocoa, the swap ratios are in baking with cocoa powder.
What makes brownies fudgy instead of cakey?
More fat and less flour, first of all: this recipe uses equal volumes of butter and flour, which leans fudgy, and more flour or an extra egg would push it toward cake. Then minimal stirring once the flour goes in, because stirring develops gluten and gluten makes a bready crumb; fold until the streaks disappear, then stop. And finally, taking them out early. A clean toothpick means they are already overbaked; moist crumbs mean they will finish setting as they cool. For that shiny, crackly top everyone photographs, whisk the eggs with the butter and sugar for a full minute, which dissolves more of the sugar so it forms a thin, glossy crust in the oven.
Should you use natural or Dutch-process cocoa for brownies?
Either works here, because this recipe is leavened by eggs rather than baking soda. Natural cocoa gives a brighter, slightly fruity chocolate flavor and a reddish-brown crumb; Dutch-process gives a darker color and a smoother, milder taste. The choice matters far more in cakes that rely on baking soda, as explained in our guide to the best cocoa powder for baking.
Can you make these brownies dairy-free, and how do you store them?
For dairy-free, replace the butter with a third of a cup plus one tablespoon, about 90 g, of melted coconut oil or a neutral oil; butter is roughly 80% fat, so you need a little less oil, and the brownies come out slightly softer and less buttery. Check that your chocolate chips are dairy-free too. Stored airtight at room temperature they keep three to four days, and the edges dry out first, so leave the pan uncut if you can. In the fridge they keep up to a week and turn fudgier and firmer. Wrapped and frozen, they keep three months; thaw at room temperature. If you want tall, cake-like brownies instead, add an extra egg and a quarter cup more flour; for one or two servings, a chocolate mug cake is faster, and for a molten center, try a chocolate lava cake.
The cocoa is the flavor
In cocoa-only brownies there is nothing for the cocoa to hide behind, which is why this is the best first test of any new tin. The cocoa Grevista distributes is natural (non-alkalized), unsweetened, single-origin Vietnamese Trinitario cocoa, and the 17.6 oz (500 g) box holds enough for about 11 batches of this recipe, based on USDA cup weights.
Grevista is our own brand: we distribute this cocoa and earn revenue when you buy it on Amazon. Disclosure.

Frequently asked questions
Is this an easy brownie recipe with cocoa powder?
Yes. It is an easy one-bowl recipe: melt the butter, whisk in the sugar, eggs, cocoa and salt, then fold in the flour. There is no mixer and no melted chocolate, and it takes about 10 minutes to mix before baking.
Can I use cocoa powder instead of melted chocolate in brownies?
Yes. A cocoa-powder recipe like this one is built for it. To convert a melted-chocolate recipe, use 3 tablespoons of cocoa plus 1 tablespoon of fat for each ounce of unsweetened chocolate.
How do I get a more intense chocolate flavor in cocoa brownies?
Add ¼ tsp more salt, a teaspoon of instant espresso powder, or mix the cocoa into the warm melted butter before adding the eggs. A fresh, aromatic cocoa also makes a noticeable difference.
Why are my brownies cakey?
Usually too much flour, overmixing after the flour goes in, or overbaking. Pull them when a toothpick still shows moist crumbs.
Can I double this recipe?
Yes. Use a 9×13-inch (23×33 cm) pan and start checking at 25 minutes.
Do I need to sift the cocoa powder?
It helps. Cocoa clumps easily, and lumps that survive into the batter bake into dry, bitter pockets.
Can I use cacao powder instead of cocoa powder in brownies?
Yes. Unsweetened cacao powder swaps 1:1 for the cocoa here. It is usually natural, non-alkalized cocoa, so follow the natural-cocoa notes above; the brownies come out a shade lighter with a slightly fruitier taste. The labels are explained in cacao vs cocoa powder.
