Ingredients You’ll Need
These ingredients might seem simple, but each one plays a starring role in creating the perfect balance of flavor and texture in your Vegan Italian Meringue Buttercream Recipe. From creating the glossy meringue base to adding rich creaminess, this list is carefully crafted to deliver excellence with minimal fuss.
- Caster sugar (250 g, separated into 200g and 50g): Essential for that glossy, sweet meringue and the final silky sweetness.
- Water (60 ml): Combines with sugar to create the hot syrup that sets the meringue’s structure.
- Aquafaba (234 g): The magical chickpea liquid that whips just like egg whites, giving this buttercream its airy body.
- Cream of tartar (¼ teaspoon): Stabilizes the aquafaba foam, ensuring your meringue stays light and voluminous.
- Vegan block butter (250 g, room temperature, cut into chunks): Adds the luxurious, creamy texture we love in buttercream, making it rich and spreadable.
- Vanilla extract (1 teaspoon): For that warm, inviting flavor note that makes every bite comforting and delicious.
How to Make Vegan Italian Meringue Buttercream Recipe
Step 1: Reduce the Aquafaba
Start by pouring the aquafaba into a saucepan and bringing it to a boil. Then reduce the heat and let it simmer until you’ve reduced the volume down to half a cup. This concentrating step deepens the flavor and strengthens the meringue’s structure so your buttercream whips beautifully every time.
Step 2: Chill the Reduced Aquafaba
Transfer the cooled, reduced aquafaba to a jar and refrigerate it. Doing this in advance, ideally overnight or at least one hour prior, helps achieve that perfect fluffy meringue base when whipping.
Step 3: Make the Sugar Syrup
Combine 200g of caster sugar with water in a saucepan and stir gently just until the sugar forms a paste. Place it on medium-high heat and allow the syrup to simmer without stirring. Using a candy thermometer, watch closely until it reaches 116°C (240°F). This hot sugar syrup is crucial for stabilizing the meringue and creating that signature Italian meringue glossy texture.
Step 4: Whip the Aquafaba
In a large, dry, and clean bowl, whisk the chilled aquafaba with cream of tartar on high speed until soft peaks form—this usually takes about 5 minutes. This is the base that will transform into a fluffy, sturdy meringue perfect for buttercream.
Step 5: Add Remaining Sugar
With the mixer running, slowly add the remaining 50g of caster sugar a little at a time. Keep whisking for another 3 minutes until the mixture becomes glossy and holds firmer peaks.
Step 6: Incorporate the Hot Sugar Syrup
Carefully drizzle the hot sugar syrup into the whipped aquafaba while continuously whisking. This step ensures the syrup doesn’t cook the aquafaba but instead creates that key silky meringue texture you want in your Vegan Italian Meringue Buttercream Recipe.
Step 7: Cool the Meringue
Whisk the meringue mixture for 10 to 15 minutes until it reaches room temperature. Patience here is key—the longer you whisk, the silkier and more stable the meringue will be as the foundation for your buttercream.
Step 8: Add the Vegan Butter
Begin adding the softened butter chunks one at a time, whisking after each addition. At first, the texture will flatten and seem odd, but don’t worry! Keep adding the butter and soon it will transform into a thick, spreadable buttercream with that perfect creamy consistency.
Step 9: Final Whisk and Flavor
Once all the butter is fully incorporated, whisk on low speed for 5 minutes to perfect the texture. Then add the vanilla extract and whisk again for another 2 minutes. Now your Vegan Italian Meringue Buttercream Recipe is ready to dazzle.

Make Ahead and Storage
Storing Leftovers
Store any extra buttercream in an airtight container in the refrigerator. Because it will harden when chilled, just let it sit at room temperature and give it a gentle stir to bring back that creamy, spreadable texture before using.
Freezing
You can freeze Vegan Italian Meringue Buttercream for up to a month without compromising its texture or flavor. Freeze it in a sealed container, then thaw overnight in the fridge and whisk briefly before applying.
Reheating
When ready to use after chilling or freezing, allow the buttercream to come fully to room temperature. Whisk lightly to restore its fluffy texture, because warmth unlocks all the buttery goodness and makes it effortless to spread or pipe.
FAQs
Can I use regular egg whites instead of aquafaba?
Absolutely, but this recipe is designed specifically for a vegan alternative. Using aquafaba keeps it plant-based while still delivering that same fluffy, stable meringue needed for Italian buttercream.
Why do I need to reduce the aquafaba?
Reducing the aquafaba concentrates its proteins and sugars, resulting in a stronger meringue that holds its shape better and whips to a silkier consistency for the buttercream.
What is cream of tartar’s role?
Cream of tartar stabilizes the aquafaba foam by lowering its pH, which helps the meringue retain more volume and have a smoother texture.
Can I flavor this buttercream differently?
Definitely! Vanilla is classic, but you can easily mix in lemon zest, cocoa powder, or even espresso powder to customize the flavor to your dessert.
How long will this buttercream last?
When stored properly in the refrigerator, this Vegan Italian Meringue Buttercream can last up to a week. Just remember to bring it back to room temperature before using.

Description
This Vegan Italian Meringue Buttercream is a luscious, dairy-free frosting made by whipping aquafaba (chickpea water) into a meringue and combining it with vegan butter. Perfectly smooth and fluffy, it mimics the classic Italian meringue buttercream texture without any egg ingredients, making it ideal for vegan and allergy-friendly baking.
Ingredients
Syrup and Meringue
- 250 g caster sugar (separated into 200g and 50g)
- 60 ml water
- 234 g aquafaba (chickpea cooking liquid)
- ¼ teaspoon cream of tartar
Buttercream
- 250 g vegan block butter, room temperature, cut into 1″ chunks
- 1 teaspoon vanilla extract
Instructions
- Reduce aquafaba: Pour the aquafaba into a saucepan and bring it to a boil. Reduce heat to simmer and continue simmering until the liquid reduces to half a cup (about 5 minutes or longer if needed). Check volume by measuring; continue simmering if more than half a cup remains.
- Chill reduced aquafaba: Transfer reduced aquafaba to a jar and refrigerate for at least one hour or overnight.
- Prepare sugar syrup: Combine 200g caster sugar and water in a saucepan, stir gently to form a paste, then let sit for one minute to dissolve.
- Cook syrup: Place saucepan over medium-high heat and allow mixture to simmer without stirring. Insert candy thermometer and cook until syrup reaches 116°C (240°F), about 10-12 minutes.
- Whip aquafaba: In a large, clean, dry bowl, whisk chilled aquafaba and cream of tartar on high speed for 5 minutes until soft peaks form.
- Add remaining sugar to aquafaba: Gradually add remaining 50g caster sugar one dash at a time while whisking continuously. Continue whisking for 3 more minutes until sugar is fully incorporated.
- Combine syrup and aquafaba: Slowly drizzle the hot sugar syrup into the whipped aquafaba while whisking continuously to incorporate fully.
- Cool meringue: Whisk the meringue mixture for 10-15 minutes until it cools to room temperature and becomes glossy.
- Add vegan butter: Gradually add chunks of vegan butter one at a time, mixing well and allowing about 5 seconds of incorporation between additions. The mixture will initially flatten but will thicken as more butter is added.
- Whisk buttercream: Once all butter is incorporated, whisk on low speed for 5 minutes to achieve a smooth, thick consistency.
- Flavor with vanilla: Add vanilla extract and whisk on low speed for another 2 minutes to combine.
- Storage: Store the buttercream in an airtight container in the refrigerator. It will firm up when chilled, so allow it to come to room temperature before using to return to a creamy texture.
Notes
- Reducing aquafaba intensifies its ability to mimic egg whites and improve meringue stability.
