Vegan Fudgy Brownie




My Vegan Fudgy Brownie is deeply chocolate with a fudgy center and crackly sugar top. As a modified version of my Fudgy Chewy Brownie recipe, this one uses vegan butter sticks and a precise formula of sugar to water to create a wonderful fudgy texture that gets better as it rests. I’ll have a detailed photo tutorial up soon.

Measure by weight, if possible.
Measuring by weight is the best way for you to replicate my recipes. I develop recipes using ingredients (even liquids) measured in grams, which is why you see them listed first in the recipe cards. For measurements under 5 grams, I will typically only list the volumetric measurements (teaspoons, etc.), as most home scales are not precise for such small weights.
In most cases, I have converted grams to volumetric measurements (aka US customary units) for bakers who prefer this method. However, the measurements are not as precise and may have awkward proportions. The recipes should still work, but for the ultimate precision, try to use weight.
This is the OXO scale I use daily. I also purchased this budget version of a good scale, which I keep at my Mom’s house for baking. If you’re interested in other tools I use for my baking, I’ve compiled a list here.
Use room temperature ingredients.
All my ingredients should be used at room temperature, or 65-75 °F/18-24 °C. I will always indicate if you need something outside this range. If no details are given, room temperature is the default.
Pay attention to the ingredient descriptions.
I try not to be brand-specific, but I will always note an interesting result from a type of ingredient, be it negative or positive.
A specific note regarding salt: I use Diamond Crystal Kosher salt for everything on this site except for frostings. In frostings, you want the salt to dissolve more easily, and kosher salt tends to leave granules behind. If you substitute table salt (more finely granulated) for recipes that list kosher salt, you must use half the volume indicated in my recipes.
Substitutions are hard.
That said, substitutions aren’t impossible but can be the toughest part of recipe development. Small swaps, like reduced-fat milk (2% fat) for whole milk (3.5% fat), usually work fine. However, bigger changes—such as replacing oil with applesauce or sour cream with Greek yogurt—can significantly impact texture and density.
Be wary of general, all-purpose substitutions in baking; I find that usually there is never a one size-fits-all solution. I carefully select ingredients for my recipes, so for the best results, start with the original recipe and modify with caution.
Read all the recipe instructions before beginning.
I’m in the “Pre-read the Chapter before Class Lecture” club... and I invite you to join! Baking new recipes can be intimidating, so let’s set you up for success. I want you to think about timeframes. Most fillings and frostings can be made ahead of time, and give you an extra day for mental space. Also, as you become a more proficient baker, you can anticipate and recognize steps. (“Oh, this has a meringue step, so I’ll need an extra clean bowl…” etc.) Ensure you go down the ingredient list and have everything at the right temperature.
Vegan Fudgy Brownies




- 90 g (6 tablespoons) vegan butter* (from a stick, not tub)
- 80 g (¾ cup plus 1 tablespoon) Dutch-processed cocoa powder**
- 240 g (2 cups) powdered sugar
- 74 g (5 tablespoons) boiling water
- 7g (1 ½ teaspoon) vanilla extract
- 1 tsp kosher salt (I use Diamond Crystal Kosher)
- 97 g (¾ cup + 1 tablespoons) all-purpose flour, bleached or unbleached
- 113 grams (about 4 ounces) vegan chocolate*** chips or chunks from a bar (optional, but adds bits of chocolate throughout the internal brownie)

- 74 g (5 tablespoons) boiling water

- Prep the pans, oven, and chocolate.
Arrange a rack in the middle of your oven and preheat to 350°F/180°C. Prepare a pan by lining it either with foil or parchment paper and lightly grease.
If you’re using a chocolate bar, chop it into pea-sized chunks. - Make cocoa powder paste.
Melt the vegan butter in a small heat-proof bowl until liquid and very warm, about 1 minute. Add the cocoa powder to the butter and stir to combine. It should be thick and smell very chocolatey. Set this aside. - Mix the water with powdered sugar.
Add the powdered sugar to a large mixing bowl. Pour in the boiling water and whisk until sugar is dissolved. Whisk in the warm cocoa powder paste until the mixture is fully combined, thick, and shiny.
Stir in the vanilla and salt. - Add the flour.
Use a spatula to fold in the flour. The batter will be thick. - Pour batter into a pan and add chocolate pieces.
I like to preserve the crackly sugar top on my brownies, so I set aside about a fourth of the batter. Then, I mix the chocolate pieces into the remaining larger quantity of batter and pour that into the pan. I then pour the batter I set aside on top on, smooth it out.
You can also just pour the chocolate pieces into all the batter; the brownies will still have a crackly top, albeit studded with chocolate pieces, which is still pretty. - Bake for about 25-30 minutes.
Place the brownie pan on the middle rack. Start checking at 23 minutes. The final brownies should have puffed up with a glossy crystallized sugar top. If you have a thermometer, I remove my brownies when their centers are around 200°F/93°C.
Keep in mind that eggless brownies usually take longer to bake because their structure depends more heavily on flour gelatinization, which takes longer than the setting process in egg-based brownies. - Cool brownies completely in the pan.
Along the same lines, eggless brownies take longer to set once cool. For the ultimate chewy, fudgy texture, let them cool completely to room temperature in the pan before slicing. They become even chewier the next day.

Recipe Card - Adriana's Notes
*I used Country Crock Homestyle Plant Butter, Unsalted to create this recipe. Tub-based vegan butters usually have more water and may result in a lack of a crackly top on the finished brownie.
**You can use any type of cocoa powder here, but I prefer Dutch-processed or European-style cocoa. It has a beautiful dark color and mellow chocolate flavor. In this recipe, I’ve used the Rodelle Dutch-processed cocoa powder.
***You can use any type of chocolate here, such as chips or cut-up chunks from a bar. If you prefer a sweeter brownie, go for vegan chocolate with a lower percentage, which typically contains more sugar.
