Ingredients You’ll Need
Simple and straightforward, the ingredients for this Vegan Swiss Meringue Buttercream Recipe are easy to find and each plays a crucial role in building that perfect fluffy and creamy texture.
- Aquafaba: This magical chickpea brine whips up just like egg whites for that essential meringue base.
- Caster sugar: Superfine sugar dissolves beautifully in the warm aquafaba, giving sweetness and stability.
- Cream of tartar (optional): A pinch helps stabilize the meringue for maximum fluffiness and volume.
- Vegan block butter: Adds richness and that classic buttery texture; make sure it’s softened to room temperature for easiest mixing.
- Vanilla extract: Brings warmth and depth to the final buttercream, rounding out the sweetness perfectly.
How to Make Vegan Swiss Meringue Buttercream Recipe
Step 1: Dissolve Sugar in Aquafaba
Start by ensuring your mixing bowl is spotless and completely dry—this small detail will make all the difference in whipping success. Combine the aquafaba and caster sugar in the bowl, then set it over a saucepan of simmering water, creating a bain-marie. Keep the mixture at medium heat and stir occasionally until the sugar has fully dissolved and you notice the mixture warming up nicely. This warming step is critical to get a smooth meringue that will hold together perfectly.
Step 2: Whisk Aquafaba Mixture to Stiff Peaks
Remove the bowl from heat and switch to an electric whisk or your stand mixer. Add the optional cream of tartar now to help with stability. Whisk on high speed for about 15 to 20 minutes until the mixture cools down and turns glossy, stiff, and holds firm peaks. You can even test by carefully tipping the bowl upside down—the meringue should stay put without sliding. This glossy stiffness is the hallmark of a great Swiss meringue base.
Step 3: Incorporate Vegan Butter
Begin adding the room-temperature vegan butter chunks little by little into the meringue, just one piece at a time. Beat briefly after each addition—about 5 seconds should do. It’s normal for the mixture to lose some volume and look a bit flat early on. Don’t panic; this part requires patience and steady blending to come together beautifully.
Step 4: Whip Until Light and Fluffy
Once all the butter has been combined, reduce your mixer to low and continue whisking for 5 to 10 minutes. Watch the mixture transform as it thickens, lightens in color, and becomes fluffy and creamy. If at any point it seems split or curdled, just keep whisking—you’ll be rewarded with a luxuriously smooth and airy buttercream.
Step 5: Add Vanilla Extract
Finish by folding in the vanilla extract and whisk for a couple more minutes until fully mixed. This final step brings a fragrant, comforting note to your Vegan Swiss Meringue Buttercream Recipe, elevating it from simple frosting to a mouthwatering delight.
How to Serve Vegan Swiss Meringue Buttercream Recipe
Garnishes
This buttercream pairs beautifully with fresh berries, edible flowers, or a sprinkling of finely chopped nuts. These garnishes add a lovely texture contrast and a burst of fresh flavors that brighten each bite when served on cupcakes or layered cakes.
Side Dishes
Though it’s a frosting, pairing desserts topped with this Vegan Swiss Meringue Buttercream Recipe alongside a cup of rich vegan hot chocolate or a refreshing citrus sorbet creates an indulgent yet balanced experience. The cool tanginess of citrus sorbet cuts through the sweetness perfectly, while the hot chocolate complements the creamy texture.
Creative Ways to Present
For a gorgeous presentation, try piping the buttercream in decorative swirls or rosettes using a star-tipped nozzle. You can also incorporate natural food coloring to tint the buttercream in pastel shades for celebrations or themed parties. Another fun idea is layering it between colorful vegan cake layers for a vibrant surprise inside.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftover frosting, store it in an airtight container in the refrigerator. Keep in mind it will firm up considerably when cold, so bring it back to room temperature and re-whip briefly before using it again.
Freezing
You can freeze this buttercream to keep it fresh longer. Place it in a sealable freezer-safe container, and when ready to use, thaw it overnight in the fridge. Once thawed, allow it to warm to room temperature and whisk to restore its light, fluffy texture.
Reheating
Avoid applying direct heat when reheating. Instead, simply let your buttercream sit at room temperature for an hour or two before re-whipping with a mixer to return its creaminess and make it easy to spread or pipe.
FAQs
Can I use aquafaba from canned chickpeas for this recipe?
Absolutely! Aquafaba from canned chickpeas is the most convenient and widely used option for the Vegan Swiss Meringue Buttercream Recipe. Just make sure it’s well drained and free of any added spices or salt.
What if my meringue doesn’t get stiff enough?
If your aquafaba mixture is still soft after whisking, check that your bowl and whisk were completely clean and dry. Also, ensure you heated the sugar and aquafaba mixture thoroughly to dissolve the sugar. Continuing to whisk for a few extra minutes usually helps as well!
Can I flavor the buttercream with things other than vanilla?
Definitely! While vanilla is classic and delicious, you can swap in extracts like almond, lemon, or peppermint, or even fold in cocoa powder for a chocolate twist in your Vegan Swiss Meringue Buttercream Recipe.
Is this buttercream stable for hot weather?
This buttercream is more stable than traditional whipped frostings but can soften in very warm temperatures. It’s best to keep frosted desserts in a cool environment until serving to maintain their shape.
Can I use margarine instead of vegan butter?
It’s best to use a firm, quality vegan block butter for this recipe, as margarine often contains too much water. The fat content and consistency of vegan butter yield the creamiest and most stable Vegan Swiss Meringue Buttercream Recipe.
Final Thoughts
This Vegan Swiss Meringue Buttercream Recipe is a wonderful revelation for anyone craving a dairy-free frosting that doesn’t compromise on taste or texture. Whether you’re celebrating a special occasion or simply elevating your everyday baking, this frosting will add that perfect creamy, fluffy touch that makes desserts unforgettable.

Vegan Swiss Meringue Buttercream Recipe
- Total Time: 30 minutes
- Yield: 16 servings 1x
- Diet: Vegan
Description
This Vegan Swiss Meringue Buttercream is a light, fluffy, and creamy frosting perfect for cakes and cupcakes. Made with aquafaba as an egg white substitute and vegan butter, it replicates the traditional Swiss meringue buttercream texture and flavor while being entirely plant-based. It’s stabilized with optional cream of tartar and flavored with vanilla extract, offering a smooth and glossy finish that’s easy to whip up using a bain-marie and an electric mixer.
Ingredients
Buttercream Ingredients
- 9 tablespoons aquafaba (the liquid from a can of chickpeas)
- ¼ teaspoon cream of tartar (optional, helps stabilize the meringue)
- 220 g caster sugar (superfine sugar)
- 250 g vegan block butter, room temperature, cut into 1-inch chunks
- 1 teaspoon vanilla extract
Instructions
- Prepare the Sugar Syrup: Take a large clean, dry bowl free of grease and add the aquafaba and caster sugar. Set this bowl over a saucepan containing a few inches of simmering water, creating a bain-marie (water bath). Heat on medium, stirring occasionally, until the sugar fully dissolves and the mixture is warm to touch, about 3-5 minutes.
- Whip the Meringue: Remove the bowl from the heat. Using an electric whisk or stand mixer, add the cream of tartar and beat the mixture on high speed for 15-20 minutes until it is completely cooled, glossy, and forms stiff peaks that hold their shape when the bowl is turned upside down carefully.
- Incorporate the Vegan Butter: Begin adding vegan butter chunks slowly, one at a time, allowing each piece about 5 seconds to incorporate before adding the next. The mixture will deflate and appear liquid but continue adding all the butter. It will thicken and become creamy once fully combined.
- Whisk Until Fluffy: After all butter is incorporated, whisk on low speed for 5-10 minutes until the buttercream is light, fluffy, and slightly pale in color. If it appears separated or curdled, continue mixing—it will come together with time.
- Add Vanilla Extract: Finally, add the vanilla extract and whisk a couple of minutes until evenly combined and smooth.
- Storage: Transfer the buttercream to an airtight container and refrigerate if not using immediately. It will firm up when cold, so allow it to come to room temperature and re-whip lightly before spreading.
Notes
- Aquafaba is the liquid from canned chickpeas and acts as an egg white substitute to create the meringue texture.
- Cream of tartar is optional but helps stabilize the meringue, resulting in a firmer buttercream.
- Use a high-quality vegan block butter with a similar fat content to dairy butter for the best texture.
- If the buttercream splits or looks curdled, keep mixing; it will come back together with patience and mixing.
- Store buttercream in an airtight container in the fridge for up to 1 week, or freeze for longer storage.
- Before use, bring to room temperature and whip to restore creamy consistency.
