Ingredients You’ll Need

  • 1/2 cup (120ml) aquafaba (liquid from canned chickpeas)
  • 1/2 cup (100g) granulated sugar

Step-by-Step Instructions:

  1. Prepare the Meringue Base: In a heatproof bowl of a stand mixer, combine the aquafaba, granulated sugar, and cream of tartar.
  2. Create the Swiss Meringue: Fill a saucepan with about an inch of water and bring it to a simmer. Place the bowl with the aquafaba mixture over the simmering water, ensuring the bottom of the bowl doesn’t touch the water. Whisk constantly until the sugar dissolves and the mixture reaches 160°F (71°C) on a candy thermometer.
  3. Whip to Stiff Peaks: Transfer the bowl to the stand mixer fitted with the whisk attachment. Whip on high speed for 5-7 minutes, or until the meringue is glossy, white, and forms stiff peaks. The bowl should feel cool to the touch.

  2. Add Remaining Ingredients: Once all the butter is incorporated, add the powdered sugar, vanilla extract, and salt.
  3. Whip to Perfection: Increase the mixer speed to high and whip for another 2-3 minutes, or until the buttercream is light, fluffy, and spreads easily.

Tips for Success

  • Aquafaba Consistency: Use the liquid from canned chickpeas, as it tends to be thicker and more consistent. If your aquafaba is watery, simmer it for a few minutes to reduce and thicken slightly.
  • Temperature Control: Heating the aquafaba mixture gently over simmering water is crucial for dissolving the sugar and creating a stable meringue.
  • Room Temperature Ingredients: Ensure your vegan butter is softened to room temperature for optimal creaminess. Cold butter can lead to a lumpy buttercream.

Flavor Variations

Once you’ve mastered the basic recipe, the flavor possibilities are endless!

  • Chocolate: Add 1/2 cup of unsweetened cocoa powder with the powdered sugar.
  • Coffee: Mix in 1-2 tablespoons of instant espresso powder for a mocha twist.
  • Lemon: Stir in the zest of one lemon and 1-2 tablespoons of lemon juice for a refreshing citrus flavor.
