Does the world really need another brownie recipe? Yes, because these are the richest, most decadent homemade brownies youโll ever try. The best part is that you donโt need a mixer and theyโre made in only 1 bowl!

Weโre doing it. A big 9ร13-inch pan of homemade brownies is on the table tonight. Dessert is served.
If you google โhomemade browniesโ there are 1000s of search results. (I donโt recommend doing this if youโre hungry.) I threw my homemade frosted brownies recipe into the running back in 2014. Theyโre chewy, dense, and easy. But lately Iโve been craving something new; a different brownie option to toss into the mix. Because thatโs the best part about baking: you can constantly experiment like a mad butter-loving scientist. And, if you think about it, we can never have enough recipes combining butter, sugar, and chocolate. I even have a skillet brownie recipe, too!

Letโs Bake 1 Bowl Homemade Brownies
These brownies are lot like my 9-inch square pan of chewy fudgy frosted brownies, but thereโs a couple minor changes to yield a larger batch. Weโre using all the same ingredients:
- Chocolate: Use real chocolate and cocoa powder. You can make brownies with either or both, and I prefer both. Whatโs interesting is that cocoa powder has more pure chocolate flavor because it is not diluted with milk and sugarโso the resulting brownies are always fabulously rich. Though natural cocoa powder can be used, I suggest a dutch process cocoa powder for a deeper, smoother chocolate flavor. This brownie recipe does not* rely on chemical leaveners so either works. If a recipe does, thatโs when itโs important to remember the difference between Dutch-process vs. natural cocoa powder. (And if you love white chocolate, here are my white chocolate brownies!)
- Butter: For flavor, of course!
- Sugar: There are 2 cups of sugar in this pan of brownies. It sounds like a lot, but recipes calling for mostly unsweetened cocoa powder do not contain the extra sugar from recipes calling for semi-sweet or milk chocolate. Also, sugar does much more than sweeten brownies. It liquifies as they bake, creating a softer center.
- Eggs: Eggs are one of the main ingredients in brownies. Just as they do in my beloved flourless chocolate cake recipe, eggs bind, add richness, tenderize, and provide structure here. This brownie recipe uses 3 eggs, which give the brownies a tight crumb and fudgy texture.
- Flour: The cocoa powder takes the place of some flour, so youโll only need 1 cup in this brownie recipe. The more flour in brownies, the cakier they will taste. We want dense and fudgy brownies, so use as little flour as possible.

Why is there no baking powder or baking soda in these brownies? Adding baking powder or baking soda lifts brownies up and creates a cakier result. But today, we all want a brownie so dense and fudgy that itโs basically 1 step up from eating pure chocolate.
Youโll get a taste of how dense these brownies are when youโre mixing up the batter. Itโs so thick and so fudgy. Seriously fudgy.


How to Tell When Brownies are Done Baking
This can be tricky, so hereโs how to determine when these brownies are done. Turn the timer to 30 minutes as soon as the brownies go into the oven. Once you begin to smell that captivating scent of chocolate permeate through the kitchen, check the brownies. Even if this is at the 25 minute mark. Use a toothpick, stick it into the center, and pull it out. The brownies need more time if there is wet batter on the toothpick. If there are a few moist crumbs on the toothpick, the brownies are done. You donโt want a clean toothpick! (Thatโs an odd sentence, but you get me!)
How to Get Shiny Crackly Tops in Brownies
The secret is in the sugar! Melt the butter and 2 ounces of chocolate first, then quickly whisk in the sugar while itโs all still warm. Whisking the sugar into warm butter helps the sugar migrate to the top of the batter as the brownies bake thus creating that signature shiny and crackly top we all love!

Hereโs the real question: are you a center person or an edge person? Save me the corners please. โฅ

Description
These are the richest, most decadent homemade brownies youโll ever try. You only need a few basic ingredients, 1 bowl, and theyโre done baking in 30 minutes!
Ingredients
- 3/4 cup (12 Tbsp; 170g) unsalted butter
- 4-ounce (113g) semi-sweet chocolate bar, coarsely chopped and divided*
- 2 cups (400g) granulated sugar*
- 3 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- 1 cup (82g) unsweetened natural or dutch-process cocoa powder*
- 1 cup (125g) all-purpose flour (spooned & leveled)
- 1 teaspoon salt
- optional: 1 and 1/4 cups (225g) semi-sweet chocolate chips
Instructions
- Preheat the oven to 350ยฐF (177ยฐC) and grease a 9ร13-inch pan or line with aluminum foil or parchment paper, leaving an overhang on the sides to lift the finished brownies out (makes cutting easier!). Set aside.
- In a microwave-safe bowl, combine the butter and half (2 ounces/57g) of the chopped chocolate. Melt in 30-second increments, whisking after each, until completely smooth. Whisk in the sugar until completely combined, then whisk in the eggs and vanilla. The batter will be light brown and look a bit dull.
- Add the cocoa powder, flour, salt, remaining 2 ounces/57g chopped chocolate, and the chocolate chips. Fold it all together with a silicone spatula or wooden spoon. Batter will be very thick. Spread evenly into prepared pan.
- Bake for 30 minutes, then test the brownies with a toothpick. Insert it into the center of the pan. If it comes out with wet batter, the brownies are not done. If there are only a few moist crumbs, the brownies are done. Keep checking every 2 minutes until you have moist crumbs. Brownies typically take 31โ32 minutes in my oven.
- Remove from the oven and place on a wire rack to cool completely in the pan before cutting into squares.
- Cover and store leftover brownies at room temperature for up to 1 week.
Notes
- Make Ahead Instructions: Brownies freeze well up to 3 months. Thaw overnight in the refrigerator then bring to room temperature before serving.
- Special Tools (affiliate links): 9ร13-inch Baking Pan (Metal or Glass) | Glass Mixing Bowl | Whisk | Silicone Spatula or Wooden Spoon | Cooling Rack
- Chocolate Bars: Chocolate bars are typically sold in 4 ounce bars. 2 ounces will be melted down and 2 ounces will be chopped up and folded into the batter with the chocolate chips. I suggest Ghirardelli, Bakerโs brand, or Lindt.
- Sugar: Try the recipe with 1/2 cup (100g) light brown sugar and 1 and 1/2 cups (300g) of granulated sugar. Absolutely delicious! I wrote the recipe with 2 cups of granulated sugar to make it easier for most.
- Cocoa Powder: You can use either natural or dutch-process cocoa powder. I prefer dutch-process for a smoother flavor.
Reader Comments and Reviews
I need thin brownies to use for small parfaits. What size sheet pan should I use for a single recipe to get thin brownies?
Hi Lacey, hereโs everything you need to know about cake pan sizes and conversions.
Have you ever thought about making a dairy free version of this recipe?
Hi DC and Jack, Coconut oil would be the best option to make these dairy free, but obviously the flavor will be different.
We were told many years ago 30 or so, that coconut oil was bad for you. Why are people using It now?
Have you ever thought about making a gluten free version of this recipe?
A 1:1 gluten free flour substitute should work well here, but we havenโt tested it.
I was unable to find semi-sweet chocolate bars..they were all sold out..so I have substituted with semi sweet chocolate chips..if I use the same amount as the recipe..will they still turn out good?
Hi Nafis, We really recommend sticking with chocolate bars for this recipe. They melt much more smoothly than chocolate chips.
Which chocolate bar is recommended from these brands..canโt seem to find semi sweet chocolate bars on their site:
Ghirardelli
Lindt
Will I be able to bake 4 batches for 100 guests?
Hi Daisy, for best results, we recommend making separate batches rather than doubling, tripling, etc.
