Strain: Strain chickpeas to get ½ cup aquafaba (use chickpeas for another chickpea recipe).
Whisk To Frothy: Add aquafaba to a large mixing bowl. Using your electric beaters (with the whisk attachment if you have one), beat the aquafaba until it's foamy, about 30 seconds. Beat in 1 tsp vanilla extract and ½ tsp cream of tartar.
Add Sugar: While continuing to beat the aquafaba, slowly pour in ½ cup sugar about a tablespoon at a time.
Whisk To Stiff Peaks: Continue beating for 8 to 10 minutes, or until the aquafaba meringue is smooth and glossy. When you lift the beater out of the fluff, it should form a little peak that stays upright and doesn't fold over.

Notes
Storage: Vegan marshmallow fluff is best when fresh (it doesn’t store well and can separate or become weepy after about a day). If you’re making it for a party, I recommend whipping it right before serving for the best texture.Why isn’t my aquafaba whipping up? Ensure you’re using unsalted canned chickpeas and that the aquafaba is at room temperature. If it’s still not working, try reducing the aquafaba by simmering it gently on the stove until it thickens slightly.Can I use homemade aquafaba? You can, but results may vary. Homemade aquafaba (from dried chickpeas) often has a different starch concentration and might not whip as well. For consistent results, we recommend canned.
