How to Make Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe
Step 1: Prepare Your Mixing Bowl
Start with a completely clean and dry mixing bowl—this step is crucial because any grease or residue can stop the aquafaba from whipping properly. Give the bowl a quick wipe with vinegar or lemon juice if you want to be extra sure it’s perfectly clean.
Step 2: Melt the Sugar and Aquafaba
Combine the aquafaba and light brown sugar in a large bowl. Set this bowl over a saucepan of simmering water to create a gentle water bath. Stir occasionally and let the sugar dissolve fully into the aquafaba. This careful melting gives the frosting its lovely silky foundation and helps ensure there’s no graininess in the final texture.
Step 3: Whip Until Glossy and Stiff
Remove the bowl from the heat, then whip the mixture on high with an electric whisk or in your stand mixer. This is the fun part where the magic happens—whip for 15 to 20 minutes until it turns glossy, thick, and holds stiff peaks. A good test is to carefully invert the bowl; the meringue should stick and not slide out.
Step 4: Add Vegan Butter Gradually
With your mixer running on medium speed, slowly add chunks of room temperature vegan butter one piece at a time. Wait about 5 seconds between additions. The mixture might look a bit flat or “broken” at first, but don’t worry—it comes together beautifully after incorporating all the butter and a bit more whipping.
Step 5: Whip Until Fluffy and Light
Keep whipping on medium speed for 5 to 10 minutes. You’ll notice the buttercream becoming lighter in color and fluffier in texture, transforming into that perfectly spreadable, cloud-like frosting you dream about.
Step 6: Add Flavor with Vanilla and Cinnamon
Scrape down the sides of your bowl, then whisk in the vanilla extract and ground cinnamon (if using). Give it a final mix until everything is seamlessly combined. Now your Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe is ready to elevate your desserts to heavenly heights!
How to Serve Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe
Garnishes
This frosting’s warm brown sugar and cinnamon notes pair beautifully with a sprinkle of chopped nuts like pecans or walnuts for extra texture. Alternatively, a dusting of finely grated dark chocolate can add a beautiful contrast in both taste and presentation.
Side Dishes
Serve your frosted pastries with fresh berries or a warm cup of spiced tea or coffee to create a cozy, inviting experience that complements the sweet, velvety frosting.
Creative Ways to Present
Pipe this buttercream into delicate rosettes on cupcakes or use an offset spatula for a rustic, swooping finish on layer cakes. For a playful twist, try sandwiching the frosting between vegan cookies or swirling it into dairy-free ice cream for a decadent dessert.
Make Ahead and Storage
Storing Leftovers
You can keep any leftover Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) in an airtight container in the refrigerator for up to 5 days. Before using, bring it back to room temperature and give it a quick whip to restore its smooth, fluffy consistency.
Freezing
If you want to make the frosting ahead and freeze it, place it in a sealed container and freeze for up to 2 months. When ready to use, thaw overnight in the refrigerator and then whip it again to bring back its perfect texture before frosting your desserts.
Reheating
Reheat the frosting gently at room temperature rather than using heat, as direct heat can melt the buttercream unevenly. If needed, a quick re-whip ensures the frosting is light, airy, and ready to spread without any lumps.
FAQs
Can I make this frosting without aquafaba?
Aquafaba is essential for mimicking the Swiss meringue texture in this recipe, so skipping it will change the outcome. However, you can experiment with other vegan meringue substitutes, but results may vary.
Is the Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe very sweet?
The brown sugar provides a rich sweetness balanced by the cinnamon and vanilla, so it is sweet but not overpowering, striking a delightful balance that enhances your desserts without overshadowing them.
Can I use salted vegan butter?
We recommend using unsalted vegan butter to control the exact saltiness of the frosting. If you do use salted butter, reduce or skip any additional salt in your baked goods to keep everything balanced.
Why is my frosting grainy?
Graininess usually happens if the sugar isn’t fully dissolved during the water bath step. Make sure to stir thoroughly and allow the sugar to completely dissolve before whipping.
How do I fix a split or curdled frosting?
If the buttercream looks separated after adding butter, keep whipping—it usually comes back together after a few more minutes. Ensuring all ingredients are at the right temperature helps avoid this issue too.

Ingredients
Frosting Ingredients
- 160 g aquafaba (liquid from canned chickpeas; see note 1)
- 260 g light brown sugar
- 250 g vegan butter, room temperature (see note 2)
- 2 tablespoons ground cinnamon (optional)
- 1 teaspoon vanilla extract
Instructions
- Prepare Your Equipment: Ensure your stand mixer bowl or mixing bowl is completely clean and dry. Wipe it with a little vinegar or lemon juice to remove any residue that might interfere with the frosting.
- Melt the Sugar: Combine the aquafaba and light brown sugar in a large heatproof bowl. Place this bowl over a saucepan containing a few inches of simmering water to create a double boiler (water bath). Stir occasionally until the sugar is fully dissolved, which should take a few minutes.
- Whip the Mixture: Remove the bowl from the heat. Using an electric whisk or stand mixer, beat the sugar-aquafaba mixture on high speed for 15-20 minutes until it cools down completely and becomes stiff, glossy, and stable enough to hold its shape—even when the bowl is turned upside down carefully.
- Incorporate the Butter: Add softened vegan butter slowly, piece by piece, waiting about 5 seconds before adding the next piece. The mixture may appear to deflate at first but will become thicker and fluffier as more butter is incorporated.
- Whip Until Fluffy: Continue whisking at medium speed for an additional 5-10 minutes until the frosting is light, airy, and has a lighter color. If the mixture looks separated or split at any point, persist with the whipping process as it will eventually come together.
- Add Flavorings: Scrape down the sides of the bowl with a spatula to ensure even mixing. Add the vanilla extract and ground cinnamon (if using) and whisk for another couple of minutes until fully combined and smooth.
Notes
- Note 1: Aquafaba is the viscous water in which legume seeds such as chickpeas have been cooked. It mimics egg whites’ properties in vegan baking and frostings.
- Note 2: Use high-quality vegan butter that is solid but soft enough to cream easily at room temperature. Avoid margarine with high water content.
- Make sure all your equipment is free from grease or oil to help achieve the perfect meringue consistency.
- This frosting is best used immediately or stored in the fridge and re-whipped before use.
