Preheat the oven to 325°F (160°C). Prepare an 8- x 8-inch square pan with a sheet of parchment paper with the edges hanging over the sides of the pan. (To do this, place a piece of parchment across the pan, leaving the excess to drape over the sides — essentially creating “handles” for removing the baked brownies later.)
Add the aquafaba and cream of tartar to the bowl of a standing electric mixer fitted with the balloon whisk attachment. Whip the aquafaba on low for about 10 seconds to lighten. Raise the speed to medium and whip for 5 minutes. Increase the speed to medium-high and continue to whip for another 5 minutes or until the aquafaba holds firm peaks.
Add the granulated sugar, 2 tbsp at a time, and beat to blend. When all of the granulated sugar has been added, begin adding the brown sugar in the same fashion. This should take about 3 minutes to accomplish. Then, continue to whip for an additional 2 minutes or until the sugar has dissolved and the meringue is climbing the side of the bowl.
Note: The aquafaba acts as an emulsifier and light leavener in the brownies.

Preparing & Baking the Brownies
Ingredients
3/4 cup unsweetened Dutch-process cocoa powder
3/4 cup unbleached all-purpose flour
1/2 tsp sea salt
1/2 tsp baking powder
1/4 cup neutral canola or other neutral oil
2 tbsp non-dairy milk
2 tsp pure vanilla extract
Sift together the cocoa, flour, salt and baking powder in a medium bowl. Note: Make sure to use Dutch-process cocoa powder for this recipe.
Sift the cocoa mixture over the meringue in the mixing bowl. Pour the oil, non-dairy milk and vanilla directly over the cocoa mixture and, using a rubber spatula, fold the mixture together until a pourable batter forms without any obvious air bubbles.
Spoon the batter into the prepared pan. Transfer to the preheated oven and bake for approximately 40 minutes or until a tester inserted into the middle comes out clean or with only a few moist crumbs attached. Do not over-bake. Note: If using a glass baking dish the baking time maybe a bit longer.
Remove from the oven and immediately run a knife around the edges of the pan. Grasping the overhanging parchment paper, lift the brownies to a wire rack to cool cool completely before cutting and serving.

Hello!
Sorry for the maybe stupid question but.. What is cream of tartar?
Thank you :)
Hi Rhea Maria, Cream of tartar is actually a powdered acid that helps activate leavening. You can find it in the spice section of your grocery store. Cheers, Sandy
Thank you Sandy,
In the recorded event it was mentioned we could substitute cream of tartar with lemon. Do you know what the ratio would be? And what would be the best way to prepare aquafaba when cooking our own chickpeas?
Hi Rhea Maria, Generally speaking you can substitute 1 tsp of lemon juice or white vinegar for 1/2 tsp of cream of tartar, though this can vary. With homemade aquafaba, you are looking for a viscous liquid so the proteins can trap the air bubbles. However you cook your chickpeas, you may need (after straining) to reduce the liquid down to achieve the proper viscosity for the application at hand.
