The rich, fudgy base is loaded with melty chocolate chips, while the bandage-style frosting gives you all the Halloween swagger without fancy piping skills. Make them for a Halloween party or to serve to your besties, Elvira and Art the Clown, for breakfast, lunch, and dinner. They obviously consume nothing but vegan Halloween treats right?
Made these tonight and my family loved them! They are satisfying and everything a great brownie should be-my fiancé commented that this recipe is better than my regular brownies! I love the color and was glad I had purchased the dark cocoa. I want to make more for Halloween to share with neighbors. Fun to decorate, too. Super cute!

🥰Why you'll adore this Halloween brownie recipe
✊ Vegan AF: Like all of my vegan desserts, this one ghosts all the dairy and eggs-no no eye of newt up in here.
💥 Double the Chocolate: Melted chips, black cocoa, plus extra unmelted chips, means each bite has a perfect mix of smooth and melty with tiny bursts of chocolatey goodness.
✅ Tested and Approved Worldwide: Like all of my vegan recipes, this one was tested by a massive team of recipe testers (actual living humans, and zombies alike) with spooky-good results.
👻Vegan mummy brownies ingredients
The Flours
All-purpose flour is the scaffolding that holds up all that melty chocolate drama. Without it, you'd be left with goo in a pan (which, admittedly, still tastes good, but let's aim higher). If you're baking for the gluten-free crew, swap in a 1:1 gluten-free blend, but whatever you do, keep the tapioca starch.
Tapioca starch gives these brownies their perfectly chewy texture. I use tapioca starch in my crispy-edged vegan oatmeal cookies, too, and it never lets me down in improving the texture. If you're out, potato starch can pinch-hit in a similar way, but tapioca brings a little extra finesse to the crumb.
Black Cocoa Powder
Because light brown brownies are basically chocolate cake in denial, I lean hard into black cocoa powder. This ultra-dark, low-acid cocoa turns your brownies nearly noir with a subtle Oreo-like flavor that's straight-up lovely. I use it all the time in recipes like my vegan chocolate babka and vegan flourless chocolate cake. Dutch-process cocoa will work, but just know your brownies will come out more middle-school brown than full-on haunted mansion black.
The Chocolate Chips
Melting semi-sweet vegan chocolate chips creates the base of the batter, giving it a rich, fudgy foundation. I also toss in a full cup of unmelted chips at the end for contrast, so you get both silky chocolate flow and those occasional chunky, melt-in-your-mouth landmines of joy.
Apple Cider Vinegar
Apple cider vinegar reacts with the baking soda to give these brownies just enough lift to keep them from feeling like dense fudge bricks. But its real superpower is helping curdle the soy milk, which gives the batter a smoother, more "made with buttermilk" texture. I use this same method in my vegan apple cider donuts, vegan gingerbread donuts, and vegan pancakes. Don't worry, the acidity totally vanishes when it's balanced by the sugar in the recipe.
Vegan Butter
My go-to is Earth Balance Buttery Sticks because they've got that solid fat content and reliable flavor. Trader Joe's version is more budget-friendly but comes in a different-from-stick shape in a wrapper that has no tablespoon markings, which makes it a little more annoying to measure. You can also make your own from scratch using my dairy-free butter recipe in the vegan dairy crash course.
Powdered Sugar
Powdered sugar is the base of the mummy frosting, giving it that smooth, classic sweetness. But heads-up: not all powdered sugar is vegan. Many brands still use bone char filtration (yep, actual animal bones) to process their cane sugar into a bright white powder. Look for specifically vegan-labeled ones, or just do some digging on the ol' internet to keep things fully plant-based.
Candy Eyes
The candy googly eyes take these from "brownie" to "boo!" Most baking aisles carry them this time of year, but double-check the ingredients: many are made with non-vegan confectioner's glaze. Either find a vegan-friendly version or DIY it using my vegan royal icing recipe, made a little thicker with just a touch less liquid to hold that perfectly round, unblinking stare. I use the same icing for decorating vegan Christmas cookies, and it's super versatile for artsy projects like this one.

📖 How to make vegan Halloween brownies
Follow the step-by-step photos below to get mummyfied on your very first try. If you're just here for the goods, scroll on down to the printable recipe card and get bakin'.
Step One
The Blair Whisk Project:
Preheat the oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper. In a small bowl, whisk together the tapioca starch, all-purpose flour, black cocoa powder, sugar, salt, and baking soda.
Step Two
Melter Skelter:
Melt 1¼ cups of semi-sweet vegan chocolate chips in a double boiler or heatproof bowl set over simmering water, stirring until smooth.
Step Three
Batter Watch Out:
Stir the soy milk, apple cider vinegar, vegan butter, and vanilla extract into the melted chocolate mixture.
Step Four
Stir of Echoes:
Add the wet ingredients to the dry and stir until just combined. Fold in the remaining 1 cup of unmelted semi-sweet vegan chocolate chips.
Step Five
Bring Her Bake:
Spread the batter evenly into the prepared pan. Bake for 30-32 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs. Let cool completely.
Step Six
Beaten to Death:
Meanwhile, beat the softened vegan butter until smooth. Add the plant-based milk, powdered sugar, and vanilla extract. Beat until light and fluffy.
Step Seven
Stabby Stabby:
Cut the cooled brownies into 8 rectangles.
Step Eight
Eye Know What You Did Last Summer
Transfer the frosting to a piping bag with a small flat or round tip. Pipe two dots somewhere on the upper ⅓ of each brownie. Press 2 candy eyes onto each dot of frosting.
✅ I think these look cuter when each mummy's eyes are placed a little differently. Experiment with having one eye just slightly higher than the other, or both eyes a bit off center.
Step Nine
Mummy Dearest:
Pipe diagonal lines across each brownie to resemble mummy bandages. Refrigerate for 10 minutes to help the frosting set.

👉Top tips
- Room Temp Rules: Make sure your vegan butter is truly softened or it won't cream into the chocolate mix properly. If it's too cold, it won't incorporate, and you'll end up with some greasy lumps throughout.
- Don't Overmix: Stir just until the ingredients are combined. Overmixing activates the gluten in the flour and leads to dense, rubbery brownies-aka the opposite of what we're going for. Use a spatula, not a whisk, to gently fold the mixture.
- Check Early: Start checking for doneness at 28 minutes. Every oven is a little different, and overbaking dries them out fast. Look for a few moist crumbs on the toothpick-wet means underbaked, clean means you've gone too far and will have bone-dry, sucky brownies.
🤷♀️ Recipe FAQs
Add a little extra vegan butter to thin, or sift in more powdered sugar to thicken.
Nope! A zip-top bag with a snipped corner works just fine.
Yes. Microwave the chocolate chips in 20-second bursts, stirring in between until melted.
👻 Storing: Store decorated brownies in an airtight container for up to 5 days. If your kitchen is warmer than 75 degrees, you should keep them under refrigeration.
❄️ Freezing: Freeze undecorated brownies for up to 2 months. Thaw overnight in the fridge.
