Ingredients You’ll Need
Getting the ingredients right is key, but you’ll be happy to know this recipe keeps it simple with a handful of essential components. Each ingredient plays a vital role in creating that smooth texture, stability, and delicious flavor that defines the Strawberry Italian Meringue Buttercream Recipe.
- Aquafaba (234 g): The magical chickpea brine that whips into a meringue-perfect protein base, making this vegan and airy.
- Superfine sugar (caster sugar) (250 g, separated): Helps create the syrup for the meringue and adds just the right amount of sweetness without grittiness.
- Water (60 ml): Used to dissolve sugar and create the perfect syrup consistency.
- Cream of tartar (¼ teaspoon): Stabilizes the meringue, ensuring it whips up fluffy and holds shape.
- Vegan stick butter (250 g, room temperature): Provides the buttery richness and creaminess essential to a classic buttercream texture.
- Freeze-dried strawberries (50 g): Packed with intense strawberry flavor and natural color, perfect for that fresh, fruity burst.
- Vanilla extract (1 teaspoon, optional): Adds depth and roundness to the flavor, enhancing the sweetness of the strawberries.
How to Make Strawberry Italian Meringue Buttercream Recipe
Step 1: Prepare and Reduce Aquafaba
Start by pouring the aquafaba into a saucepan and bringing it to a boil. Then reduce the heat and simmer gently until the volume drops to half a cup. This step intensifies the aquafaba’s flavor and gives you a concentrated base for a sturdy meringue. It’s best to prepare this ahead and chill the reduced aquafaba, allowing the process to be smoother.
Step 2: Turn Freeze-Dried Strawberries Into Powder
In a food processor, blitz the freeze-dried strawberries until they transform into a fine powder. Passing this powder through a sieve helps remove any stubborn seeds, ensuring your buttercream feels smooth while bursting with natural strawberry flavor. If you’re using pre-made strawberry powder, you can skip this step.
Step 3: Make the Sugar Syrup
Combine 200 grams of superfine sugar with water in a saucepan, stirring gently just until the sugar forms a paste. Bring it to a simmer without stirring further and keep an eye on the temperature with a candy thermometer until it hits 116 degrees Celsius (240 degrees Fahrenheit). This thick syrup is what gives the meringue its glossy, stable texture.
Step 4: Whip the Aquafaba Meringue
In a completely clean and dry bowl, whisk the chilled aquafaba with cream of tartar on high speed until soft peaks form, about 5 minutes. Gradually add the remaining 50 grams of caster sugar, one dash at a time, whisking continuously to build a glossy finish with firm peaks. This gentle incorporation of sugar makes the meringue silky and luscious.
Step 5: Combine Syrup and Meringue
Slowly drizzle the hot sugar syrup into the whipped aquafaba while continuously whisking. This crucial step cooks the meringue and creates a thick, stable texture. Whisk vigorously for 10 to 15 minutes until the mixture cools to room temperature and becomes the perfect base for your buttercream.
Step 6: Add Butter and Flavorings
Now, the magic happens. Begin adding the room-temperature vegan butter chunks one by one to the meringue, letting each piece incorporate fully before the next. The mixture will loosen and look a little flat initially but don’t worry—it will thicken beautifully. Once all the butter has joined the party, whisk on low speed for about 5 minutes until creamy and smooth.
Finally, stir in vanilla extract if using, followed by the strawberry powder, adding it gradually until your buttercream turns into a stunning pink shade with a fragrant, fruity aroma, completing your Strawberry Italian Meringue Buttercream Recipe.
How to Serve Strawberry Italian Meringue Buttercream Recipe
Garnishes
A sprinkle of fresh strawberry slices, edible flowers, or a dusting of powdered freeze-dried strawberries makes for a visually stunning finish. The light sweetness of the buttercream pairs beautifully with these garnishes, highlighting the natural strawberry essence.
Side Dishes
This buttercream is a perfect partner for simple, tender cakes like vanilla sponge or chocolate chiffon. It also complements vegan cupcakes, macarons, or even as a filling for sandwich cookies where you want a little fruity zing.
Creative Ways to Present
Try piping your Strawberry Italian Meringue Buttercream Recipe into elegant rosettes or whimsical swirls on cupcakes. You can also layer it between cake layers or use it as a decorative drizzle over vegan brownies for a surprising touch of freshness. For a fun twist, use tinted buttercream to create ombré effects with varying strawberry powder amounts.
Make Ahead and Storage
Storing Leftovers
You can store this buttercream in an airtight container in the fridge for up to a week. Keep in mind it will firm up significantly, so it’s best to bring it back to room temperature before use and re-whip lightly to restore its soft, spreadable consistency.
Freezing
If you want to keep this luscious frosting longer, freezing is a great option. Place it in an airtight container or freezer bag and freeze for up to 3 months. When ready to use, thaw it overnight in the fridge, then warm to room temperature and re-whip to regain its fluffy texture.
Reheating
Never heat the buttercream in a microwave or on direct heat as this will separate the butter and ruin the texture. Instead, let it warm naturally in a sealed container at room temperature and then re-whisk gently until smooth and creamy.
FAQs
Can I use regular egg whites instead of aquafaba?
While you could, aquafaba keeps this recipe vegan and adds a subtle, delightful flavor. Using egg whites would change the texture and the vegan aspect, but it can still work if you prefer traditional ingredients.
What if I don’t have freeze-dried strawberries?
Fresh strawberries won’t give the same intensity or shelf stability, so freeze-dried strawberries or strawberry powder are best. Alternatively, you can use natural strawberry extracts, but these won’t contribute to the buttercream’s color or texture the same way.
Is this buttercream suitable for birthday cakes?
Absolutely! Its light texture and fruity flavor make it a fantastic choice, especially if you want a less sweet but super decadent frosting that stands out from the usual buttercream flavors.
How long does it take to make this recipe from start to finish?
Including the aquafaba reduction and cooling times, plan for about 2 hours and 10 minutes. Patience here really leads to a beautifully smooth and stable buttercream that’s worth every minute.
Can I color this buttercream with food coloring?
Yes, although the strawberry powder already imparts a lovely pink hue. If you want a brighter or different shade, gel food coloring works best without altering the consistency.
Final Thoughts
Making this Strawberry Italian Meringue Buttercream Recipe is such a rewarding experience.

Description
A luscious vegan Strawberry Italian Meringue Buttercream made with aquafaba, freeze-dried strawberries, and creamy vegan butter. This light and airy buttercream combines the delicate sweetness of Italian meringue with the fresh fruitiness of strawberries, perfect for frosting cakes or cupcakes.
Ingredients
Aquafaba Reduction
- 234 g aquafaba (*see notes)
Sugar Syrup
- 200 g superfine sugar (caster sugar)
- 60 ml water
Meringue
- ¼ teaspoon cream of tartar
- 50 g superfine sugar (caster sugar)
Buttercream
- 250 g vegan stick butter (room temperature, cut into 1″ chunks)
- 50 g freeze-dried strawberries (or strawberry powder)
- 1 teaspoon vanilla extract (optional)
Instructions
- Read Recipe Completely: Please read over the recipe and instructions fully before getting started to be familiar with all steps and details.
- Aquafaba Reduction: In a saucepan, bring aquafaba to a boil, then reduce heat and simmer until it reduces to half a cup (approx. 5-10 minutes). Check volume periodically by pouring into a measuring cup. Refrigerate the reduced aquafaba until use, preferably overnight or at least one hour.
- Prepare Strawberry Powder: Blitz freeze-dried strawberries in a food processor until powdery. Let settle, then pass through a fine-mesh sieve to remove seeds. Skip if using strawberry powder.
- Make Sugar Syrup: Combine 200 g sugar and water in a saucepan, stirring gently to dissolve sugar. Bring to a simmer over medium-high heat without stirring, and cook until syrup reaches 116°C (240°F) on a candy thermometer (10-12 minutes).
- Whip Aquafaba: In a large dry bowl, whisk the chilled aquafaba and cream of tartar on high speed for 5 minutes until soft peaks form.
- Add Sugar to Aquafaba: Gradually add the remaining 50 g caster sugar, a little at a time, while continuing to whisk, then whip for an additional 3 minutes.
- Incorporate Sugar Syrup: Slowly drizzle the hot sugar syrup into the whipped aquafaba while whisking continuously. Continue whisking for 10-15 minutes until the meringue cools to room temperature.
- Add Butter: Gradually add chunks of vegan butter one at a time, allowing 5 seconds for incorporation. The mixture will deflate initially but will thicken into buttercream. Once all butter is added, whisk on low speed for 5 minutes until smooth and fluffy.
- Add Flavorings: Mix in vanilla extract by whisking on low speed for 2 minutes. Then add the strawberry powder one tablespoon at a time until fully incorporated and the buttercream is evenly pink and flavorful.
- Storage: Use the buttercream fresh for best texture or store in an airtight container in the fridge. Chill will harden it; bring it to room temperature and re-whip if needed before use.
Notes
- Aquafaba is the liquid from canned chickpeas; reducing it concentrates its protein for better meringue stability.
- Freeze-dried strawberries must be finely powdered and sifted for smooth texture; strawberry powder can be used as a shortcut.
- Use a candy thermometer for accurate syrup temperature to ensure proper meringue formation.
- Butter should be at room temperature and cut into chunks for easier incorporation.
- Buttercream will firm up when chilled; allow it to soften before spreading.
