1/2 cup aquafaba
1 cup corn syrup
2 tablespoons agar agar
4 tablespoon cocoa powder
6 tablespoons water
1/4 teaspoon salt
1 teaspoon vanilla paste/extract
Cocoa powder for dusting
Generously dust an 8×8 baking pan with cocoa powder. Set aside.
In your stand mixer, beat the aquafaba on a high level for about 10-15 minutes.
Add the corn syrup to a small saucepan and bring to a boil.
Dissolve the agar agar in the 6 tablespoons of water and then add it to the saucepan together with the cocoa powder.
Whisk the syrup continuously until it reaches a rolling boil, then add the salt and vanilla to the saucepan. Whisk to combine then remove from heat.
Turn your mixer down to low, and slowly pour the syrup mixture into the aquafaba to create a marshmallow fluff.
Quickly pour the fluff into your prepared baking pan, smooth the surface, and dust with more cocoa powder. Let it rest in the fridge for about 3 hours/overnight.
Once set up cut it into bite-sized pieces.
