- 20 g freeze-dried raspberry pieces: These bring a natural raspberry flavor and can be blitzed to a powder for a smooth finish.
- 135 g aquafaba: A fantastic egg white substitute that whips into a stable meringue perfect for vegan buttercream.
- 220 g superfine sugar: Dissolves easily to create a silky meringue without any graininess.

- 1 teaspoon vanilla extract: Enhances the flavor complexity and adds a warm, inviting note to the buttercream.
How to Make Raspberry Swiss Meringue Buttercream Recipe
Step 1: Prepare the Raspberry Powder
Start by turning your freeze-dried raspberry pieces into a fine powder for maximum flavor distribution. Using a food processor, blitz the raspberries for a few minutes until you achieve a powder-like consistency. Let it settle briefly, then sift the powder through a fine mesh sieve to remove any seeds that might otherwise affect the texture. If you have raspberry powder on hand, you can skip this step, but fresh raspberry powder always elevates the vibrancy of the buttercream.
Step 2: Heat Aquafaba and Sugar
Combine the aquafaba with superfine sugar in a heatproof bowl that fits securely over a saucepan of simmering water, creating a bain-marie. Stir the mixture gently as it warms until all sugar granules dissolve completely; this ensures your meringue will be perfectly smooth without any grit. The syrup should coat your spoon evenly without visible grains—this step sets the foundation for that glossy, dreamy meringue.
Step 3: Whip the Meringue
Remove the bowl from heat and transfer to a stand mixer or use an electric whisk. Beat at high speed for 15 to 20 minutes until the mixture has cooled completely and turns glossy and stiff peaks form. This gorgeous, cloud-like meringue is what will give your buttercream that signature light yet stable texture that we all crave.
Step 4: Incorporate the Butter
Now for the magic moment—slowly add your vegan butter chunks one at a time, letting each piece incorporate for about 5 seconds before adding another. Don’t worry if the mixture looks flat or separated at first; this is completely normal! Patience is key as the butter emulsifies with the meringue to create a luscious, silky buttercream.
Step 5: Whip Until Fluffy
Once all the butter is in, keep whisking on a low speed for 5 to 10 minutes until your buttercream lightens in color and becomes fluffy and smooth. If the frosting appears “split,” keep the faith—continuous blending will bring it all together into that creamy dream.
Step 6: Add Vanilla and Raspberry Powder
Gently fold in the vanilla extract and the raspberry powder using a spatula to avoid puffing up the powders when whisking. Then whisk briefly for a couple minutes until completely incorporated. This final step seals in those bright raspberry flavors and highlights the vanilla, rounding out the taste beautifully.
How to Serve Raspberry Swiss Meringue Buttercream Recipe
Garnishes
To complement the gorgeous pink hue and fresh raspberry flavor, consider topping your frosted cake or cupcakes with fresh raspberries, edible rose petals, or a light dusting of freeze-dried raspberry powder. These garnishes not only look stunning but also amplify the raspberry essence with every bite.
Side Dishes
This Raspberry Swiss Meringue Buttercream Recipe pairs wonderfully with a variety of vegan cakes, such as a moist vanilla bean cake or a rich chocolate layer cake. For something simpler, use it on sugar cookies or sweet muffins to add a sophisticated fruity twist that feels both indulgent and refreshing.
Creative Ways to Present
Try piping this buttercream in swirls or rosettes for an elegant touch. You can layer it between cake tiers and fleck it with whole freeze-dried raspberry pieces for texture surprises. For an extra special treat, pipe it into cupcake liners and top with a berry compote or a drizzle of melted dark chocolate, turning simple desserts into showstoppers.
Make Ahead and Storage
Storing Leftovers
If you happen to have extra buttercream (and it’s hard not to!), store it in an airtight container in the refrigerator. Keep in mind that chilling will firm up the buttercream, so bring it back to room temperature and give it a quick whip before using it again. It will keep its excellent flavor and texture for up to 3-4 days.
Freezing
For longer storage, Raspberry Swiss Meringue Buttercream Recipe freezes beautifully as well. Portion it into a freezer-safe container and freeze for up to 2 months. When you’re ready to use it, thaw overnight in the refrigerator and whip gently to restore its creamy, fluffy consistency.
Reheating
Buttercream doesn’t need traditional reheating, but if it feels too firm after refrigeration, simply allow it to sit at room temperature for 30 to 60 minutes. Then whip it on low speed to bring back that silky, spreadable texture you love.
FAQs
Can I use fresh raspberries instead of freeze-dried in this recipe?
Fresh raspberries contain too much moisture, which can destabilize the meringue and affect the texture of your buttercream. Freeze-dried raspberries or powder are best because they provide concentrated flavor without extra moisture.
What is aquafaba, and why is it used here?
Aquafaba is the liquid from canned chickpeas or other legumes, and it whips up much like egg whites, making it a perfect vegan alternative for Swiss meringue buttercream. It provides the light, fluffy structure without compromising on taste or texture.
Can I substitute the vegan butter for another fat?
Using vegan butter is important for achieving the right consistency and flavor. Margarines or oils won’t whip well and can result in a greasy or overly soft buttercream. Stick to a firm vegan block butter for the best results.
Why is my buttercream split or curdled, and how can I fix it?
It’s common for the mixture to look split while adding the butter, especially if the butter is too cold or added too quickly. Just keep whisking on a low speed, and it will come together with time. If it doesn’t, warming the bowl slightly over a water bath and then continuing to whisk can help smooth it out.
How long does the Raspberry Swiss Meringue Buttercream Recipe last once applied to a cake?
Once spread on your cake or cupcakes, it’s best enjoyed within 3-4 days if refrigerated. Remember to keep the cake covered to retain moisture and prevent the buttercream from drying out.

Making this Raspberry Swiss Meringue Buttercream Recipe is an absolute joy, and the end result is nothing short of extraordinary.

Description
This Raspberry Swiss Meringue Buttercream is a luscious, vegan frosting made from aquafaba and vegan butter, whipped to a silky, fluffy texture infused with the bright flavor and natural color of freeze-dried raspberries. It’s perfect for frosting cakes and cupcakes for a vibrant, dairy-free treat with a smooth, creamy finish.
Ingredients
Raspberry Powder
- 20 g freeze-dried raspberry pieces (or freeze-dried raspberry powder, add more to taste/for brighter color)
Meringue
- 135 g aquafaba (liquid from canned chickpeas)
- 220 g superfine sugar (caster sugar)
Buttercream
- 250 g vegan block butter (room temperature, cut into 1-inch chunks)
- 1 teaspoon vanilla extract
Instructions
- Prepare Raspberry Powder: Add the freeze-dried raspberries to a food processor and blitz for a few minutes until they become a fine powder. Let the powder settle for a minute, then sift it through a fine-mesh sieve to remove any seeds. Skip this step if using pre-made raspberry powder.
- Make the Meringue: Combine aquafaba and superfine sugar in a large heatproof bowl. Set the bowl over a saucepan with a few inches of simmering water (bain-marie). Heat over medium, stirring occasionally until sugar is fully dissolved and the syrup coats the spoon without visible granules.
- Whip the Meringue: Remove the bowl from heat. Using an electric whisk or stand mixer with a whisk attachment, beat the mixture on high speed for 15-20 minutes until it is completely cool, stiff, and glossy.
- Incorporate Butter: Slowly add the vegan butter chunks to the meringue one at a time, mixing for about 5 seconds after each addition. The mixture will initially flatten but will thicken as all butter is incorporated.
- Whip to Finished Buttercream: After all butter is added, whisk on low speed for 5-10 minutes until the buttercream is fluffy, lightened in color, and smooth. If it looks split, continue whisking until it comes together.
- Add Flavor and Color: Fold in the vanilla extract and raspberry powder with a spatula to prevent powder puffing. Whisk again gently for a couple of minutes until fully combined and evenly colored.
- Storage: Use immediately for best results. Store any leftover buttercream in an airtight container in the fridge. It will harden when chilled. Bring to room temperature and re-whip briefly before use to restore creamy consistency.
Notes
- Aquafaba is the liquid from canned chickpeas and acts as an egg white substitute for vegan meringue.
- Use room temperature vegan block butter for easier incorporation and smooth texture.
- When the mixture looks split after adding butter, keep whisking patiently; it will come back to a smooth texture.
- Freeze-dried raspberry powder adds natural flavor and color without watering down the buttercream.
- For brighter raspberry flavor, add additional raspberry powder to taste.
- Buttercream can be stored refrigerated but must be brought back to room temperature before use for spreading or piping.
