How to Make Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe
Step 1: Prepare Your Mixing Bowl
Before diving in, ensure your stand mixer bowl or mixing bowl is completely clean and dry. Wiping it down with a splash of vinegar or lemon juice helps remove any oily residues which might prevent the aquafaba from whipping up properly. This little prep step goes a long way toward achieving that perfect meringue texture.
Step 2: Melt the Brown Sugar
Combine the aquafaba and light brown sugar in a large heatproof bowl and set it over a saucepan with gently simmering water to create a bain-marie. This gentle heat helps dissolve the sugar completely into the aquafaba, creating a smooth syrup foundation for the frosting. Stir occasionally and keep an eye on it for a few minutes until the sugar has fully melted.
Step 3: Whip the Meringue
Remove the bowl from the heat and transfer the sugar-aquafaba mixture into your stand mixer (or use an electric hand whisk). Beat on high speed for 15-20 minutes until the mixture is thick, glossy, and completely cooled. You’ll know it’s ready when it forms stiff peaks and even stays in place if you invert the bowl carefully, showcasing that beautifully aerated meringue base.
Step 4: Incorporate the Vegan Butter
Now comes the buttery magic. Slowly add your softened vegan butter one chunk at a time, leaving about 5 seconds between additions. Expect the mixture to deflate temporarily – don’t worry, it will bounce back once all the butter is integrated. This slow incorporation is key to transforming the mixture into a silky, spreadable frosting.
Step 5: Whip Until Fluffy
Continue whisking on medium speed for 5 to 10 minutes. You’ll notice the frosting lighten in color and become wonderfully fluffy. If it looks a bit split or curdled, keep whisking patiently – it will come together into a smooth, luscious texture that’s buttery yet airy.
Step 6: Flavor It Up
Finally, scrape down the sides of the bowl with a spatula, add the vanilla extract and optional ground cinnamon, then whisk for a few more minutes to combine everything beautifully. The warmth of cinnamon pairs with the butter and brown sugar in perfect harmony, completing this dreamy Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe.
How to Serve Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe
Garnishes
When it comes to garnishing, think simple yet elegant. A dusting of ground cinnamon, a sprinkle of toasted pecans or walnuts, or a swipe of finely shredded coconut can add texture and visual appeal. Even a few pinches of flaky sea salt help to enhance the frosting’s sweetness and create a crave-worthy contrast.
Side Dishes
This frosting proves its versatility by pairing incredibly well with many baked goods. You can lavish it over vegan vanilla or chocolate cupcakes, spread it generously between layers of a sponge cake, or dollop it atop cinnamon rolls for a snowy finish that complements their spicy warmth perfectly.
Creative Ways to Present
For a fun twist on presentation, try piping the frosting into elegant rosettes or rustic swirls. If you’re feeling adventurous, sandwich it between two thin cookie layers for a melt-in-your-mouth treat. It also works beautifully as a filling for vegan whoopie pies or even as a dip for fresh fruit like apples or pears, inviting creative ways to enjoy this Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe.
Make Ahead and Storage
Storing Leftovers
You can store leftover Vegan Brown Sugar Frosting (Swiss Meringue Buttercream) Recipe in an airtight container in the refrigerator for up to 3-4 days. Before using, bring it back to room temperature and give it a quick whip to restore its fluffy texture—it’s just as good the next day!
Freezing
This frosting freezes beautifully. Place it in a sealed, freezer-safe container and freeze for up to 2 months. When you’re ready to use it, thaw in the refrigerator overnight and then whip it up again with a hand mixer to refresh its light, airy consistency.
Reheating
Since the frosting is primarily made from aquafaba and butter, avoid direct heating which could cause separation. Instead, simply let it come to room temperature naturally and then rewhip briefly. This gentle method helps preserve that dreamy Swiss meringue buttercream texture you love.
FAQs
What is aquafaba and why is it used in this frosting?
Aquafaba is the liquid from cooked chickpeas or other beans. It mimics the properties of egg whites, allowing this frosting to achieve a fluffy, meringue-like texture without eggs—perfect for a vegan Swiss meringue buttercream.
Can I use dark brown sugar instead of light brown sugar?
Yes! Using dark brown sugar will give the frosting a deeper, richer molasses flavor. It might slightly affect the color, turning it a bit darker, but the flavor will be deliciously intensified.
Is it necessary to use vegan butter, or can I substitute something else?
Vegan butter is ideal here because it provides the creamy, rich texture crucial for buttercream. While coconut oil or margarine might work, they can alter the flavor and consistency, so vegan butter is recommended for the best results.
Can I omit the cinnamon?
Absolutely. The cinnamon is optional and adds a warm spice note, but if you prefer a pure vanilla-brown sugar flavor, feel free to leave it out.
How long does this frosting last once applied to a cake?
Once frosted, keep your cake refrigerated and consume within 3-4 days for the best flavor and texture. Always store leftovers covered to keep the frosting fresh and soft.

Description
This Vegan Brown Sugar Frosting is a luscious and creamy Swiss Meringue-style buttercream made without eggs, using aquafaba as a perfect vegan alternative. It combines the rich sweetness of light brown sugar with the smoothness of vegan butter and a hint of cinnamon, resulting in a fluffy, glossy frosting ideal for cupcakes, cakes, and more. With a method that involves gently melting sugar over a water bath and then whipping the mixture to stiff peaks, this frosting replicates the classic texture and taste of traditional Swiss meringue buttercream without any animal products.
Ingredients
Frosting Ingredients
- 160 g aquafaba (liquid from canned chickpeas)
- 260 g light brown sugar
- 250 g vegan butter, room temperature
- 2 tablespoons ground cinnamon (optional)
- 1 teaspoon vanilla extract
Instructions
- Prepare your mixing bowl: Ensure your stand mixer bowl or any mixing bowl is completely clean and dry. Wiping it with a little vinegar or lemon juice helps remove any residue that might prevent whipping.
- 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 water bath. Stir occasionally over medium heat until the sugar completely dissolves, about 3–5 minutes.
- Whip the mixture: Remove the bowl from the heat. Using an electric whisk or stand mixer, beat the syrup at high speed for 15 to 20 minutes until the mixture cools down fully and becomes stiff, glossy, and holds its shape even when the bowl is inverted carefully.
- Add vegan butter: Gradually add the vegan butter in chunks to the whipped aquafaba mixture, spacing additions by approximately 5 seconds. The mixture might deflate initially, but it will stiffen again once all butter is incorporated.
- Whisk to fluff: Continue mixing on medium speed for 5 to 10 minutes until the frosting is light, fluffy, and pale in color. If the mixture appears curdled, keep whipping as it will come back together with enough air incorporated.
- Flavor the frosting: Scrape down the bowl sides with a spatula, add the vanilla extract and cinnamon (if using), and whisk for an additional 2 minutes until everything is fully combined and smooth.
Notes
- Use aquafaba from canned chickpeas for best results because it whips better than cooking liquid from dried chickpeas.
- Make sure the vegan butter is softened to room temperature to incorporate smoothly without lumps.
- The cinnamon adds a warm spice note but is optional depending on your flavor preference.
- The frosting is best used immediately but can be stored in the refrigerator for up to 3 days. Re-whip before use if separated.
- Ensure that no grease or residue remains in the mixing bowl to achieve maximum volume when whipping.
