Ingredients You’ll Need
This recipe keeps things simple with just a handful of essential ingredients, each playing a crucial role in creating the rich, silky texture and decadent flavor of the buttercream. From the glossy aquafaba meringue to the velvety vegan butter and bittersweet chocolate, every component is chosen carefully to ensure the perfect balance of taste and creaminess.
- Vegan dark chocolate (3.5 oz): Provides a deep, rich chocolate flavor that forms the heart of the buttercream.
- Aquafaba (9 tablespoons): The magical egg-white substitute from chickpea brine that whips into a fluffy meringue base.
- Soft brown sugar or caster sugar (1 cup): Adds sweetness and helps stabilize the meringue texture.
- Vegan block butter (8.8 oz, room temperature): Creates the creamy, spreadable consistency essential to any good buttercream.
- Dutch processed cacao powder (2 tablespoons): Enhances the chocolate depth with rich cocoa notes and smooth finish.
- Pinch of sea salt: Balances the sweetness while intensifying the chocolate flavor.
How to Make Vegan Chocolate Swiss Meringue Buttercream Recipe
Step 1: Melt the Chocolate
Begin by gently melting your vegan dark chocolate over a double boiler to ensure it melts smoothly without burning. Once melted, set it aside to cool slightly—this prevents the chocolate from cooking the meringue or butter when it’s added later.
Step 2: Prepare the Sugar and Aquafaba Syrup
Combine the aquafaba and sugar in a heatproof bowl set over simmering water to create a bain-marie. This gentle heating dissolves the sugar completely, vital for that glossy meringue texture. Keep stirring occasionally, and heat only until the sugar dissolves—no need to boil.
Step 3: Whip the Aquafaba Mixture Into Meringue
Remove the bowl from heat and whip the mixture with an electric whisk or stand mixer on high for 15 to 20 minutes. You’ll see it turn glossy, stiff, and cool to the touch. A great test here is to tilt the bowl gently to confirm the meringue holds firm without slipping—a clear sign you’re ready for the next step.
Step 4: Add the Vegan Butter Gradually
Slowly incorporate the soft vegan butter chunks one at a time into the meringue, beating well after each addition. Although the mixture may look deflated initially, patience is key—you’ll soon notice it transform into a thick, creamy frosting as all the butter fully blends in.
Step 5: Whisk Until Fluffy and Lightened
Continue whisking on low speed for 5 to 10 minutes. This lightens the texture and color, making the buttercream wonderfully airy. If your mixture seems split or curdled at this point, no worries at all—it’s part of the process, and with steady whipping, it will come back together beautifully.
Step 6: Combine Melted Chocolate, Cocoa Powder, and Salt
Pour the cooled melted chocolate into your fluffy buttercream mixture and whip it together until smooth and fully incorporated. Then add the cacao powder and a pinch of sea salt to deepen the chocolate complexity and bring all the flavors into perfect harmony.
How to Serve Vegan Chocolate Swiss Meringue Buttercream Recipe
Garnishes
Sprinkle some vegan chocolate shavings or cocoa nibs on top for added texture and a hint of crunch. Fresh berries like raspberries or strawberries also complement the rich chocolate with a burst of freshness and color contrast.
Side Dishes
This buttercream pairs splendidly with moist chocolate or vanilla vegan cakes, as well as simple cupcakes. It also adds a decadent touch to vegan brownies or whoopee pies, turning everyday desserts into decadent celebrations.
Creative Ways to Present
Try piping the Vegan Chocolate Swiss Meringue Buttercream Recipe onto cupcakes using a star or rosette tip for a beautiful effect. For cake layers, spread it generously between each tier and decorate with edible flowers or a dusting of powdered sugar to highlight its silky sheen.
Make Ahead and Storage
Storing Leftovers
Store any leftover buttercream in an airtight container in the refrigerator, where it will keep well for about 3 to 5 days. Because of the butter and chocolate, it firms up when chilled, so be prepared to soften it before using again.
Freezing
You can freeze this buttercream for longer storage; place it in a sealed container, and it should keep for up to 2 months. Thaw overnight in the refrigerator and then bring to room temperature before use, giving it a good whisk to restore its creamy texture.
Reheating
To revive your chilled or thawed buttercream, leave it at room temperature for a couple of hours. Then whip it gently to bring back the light, fluffy texture that makes the Vegan Chocolate Swiss Meringue Buttercream Recipe such a joy to spread and savor.
FAQs
What is aquafaba, and why is it used in this recipe?
Aquafaba is the liquid from canned chickpeas or cooked chickpeas that whips up like egg whites. It’s crucial in this recipe because it creates the meringue base, giving the buttercream its airy structure without using animal products.
Can I use a different type of vegan butter?
Yes! While a firm vegan block butter works best for texture and stability, some softer alternatives can also work. Just be sure the butter is at room temperature and not too soft or melted when adding.
Is Dutch processed cacao powder necessary?
Using Dutch processed cacao powder gives a smoother, less acidic, and richer chocolate flavor, which complements the buttercream beautifully. You can substitute with natural cocoa powder, but expect a slightly different taste and color.
What if my buttercream looks curdled or split?
This is common and nothing to panic about. Keep whisking, especially using a low speed and patience—usually, the mixture will come back together into a smooth, fluffy frosting as you incorporate all the butter and chocolate.
Can I make this buttercream chocolate-free?
While the chocolate is part of what makes this recipe special, you can adapt the Vegan Chocolate Swiss Meringue Buttercream Recipe by omitting the melted chocolate and cacao powder for a vanilla version. Just add a splash of vanilla extract or other flavorings to keep it delicious.

- Total Time: 30 minutes
- Yield: 16 servings 1x
- Diet: Vegan
Description
This vegan Chocolate Swiss Meringue Buttercream is a luxurious, smooth, and fluffy frosting made without eggs or dairy. Using aquafaba as an egg white substitute and vegan butter, this buttercream is rich in dark chocolate flavor with a hint of cacao powder and a touch of sea salt. Perfect for frosting cakes and cupcakes, it whips up silky and light, making it an ideal vegan alternative to traditional buttercreams.
Ingredients
Chocolate Swiss Meringue Buttercream
- 3.5 oz vegan dark chocolate
- 9 tablespoons aquafaba (liquid from canned chickpeas)
- 1 cup soft brown sugar (or caster sugar / superfine sugar)
- 8.8 oz vegan block butter (room temperature, cut into 1-inch chunks)
- 2 tablespoons Dutch processed cacao powder
- Pinch sea salt
Instructions
- Melt Chocolate: Gently melt the vegan dark chocolate over a double boiler (bain-marie) and set it aside to cool slightly.
- Heat Aquafaba and Sugar: In a large heatproof bowl, combine the aquafaba and sugar. Place this bowl over a saucepan filled with a few inches of simmering water (bain-marie). Heat the mixture over medium heat for a few minutes until the sugar dissolves completely.
- Whisk Meringue: Remove the bowl from heat. Using an electric whisk or stand mixer, beat the mixture on high speed for 15-20 minutes until it becomes completely cooled, stiff, glossy, and holds its shape firmly.
- Add Butter: Gradually add the softened vegan butter chunks, one at a time, mixing well for about 5 seconds between each addition. The mixture may flatten during this process but will firm up once all butter is incorporated.
- Whisk Until Fluffy: Continue whisking on low speed for 5-10 minutes until the buttercream is fluffy and lightened in color. If the mixture appears split, continue whisking until it comes together.
- Incorporate Chocolate and Flavorings: Add the cooled melted chocolate to the buttercream and whisk for a couple of minutes until fully combined. Then add the Dutch processed cacao powder and a pinch of sea salt, mixing for another 1-2 minutes until smooth.
- Storage Tips: Use the buttercream immediately at room temperature to frost cakes or cupcakes, or store it in an airtight container in the fridge. The buttercream will stiffen in the fridge due to the melted chocolate, so bring it back to room temperature for a few hours to restore its creamy consistency before serving.
Notes
- Aquafaba is the liquid from canned chickpeas and acts as an egg white substitute in this vegan recipe.
- Ensure the vegan butter is at room temperature for easier incorporation and smooth buttercream.

- The buttercream is best served at room temperature for optimal spreadability and texture.
- Store in an airtight container in the fridge for up to 5 days.
