Preheat your oven to 350°F. Spray an 8×8-inch baking pan with cooking spray, then line it with parchment paper. Allow the parchment paper to overhang on each side as it makes it easy to lift our baked brownies. Set aside.
Combine oil, vinegar, and essences in a bowl. Whisk until blended. Set aside.
In a large mixing bowl, sift together flour, unsweetened cocoa powder, baking soda, Instant coffee, and salt.
Set aside
Add aquafaba to a bowl.
Using the balloon attachment of your stand mixer, beat aquafaba for 4-5 minutes on medium-high speed until frothy.
Test by holding the whisk blade upside down. Aquafaba should hold its shape and not fall off the blade. Time to proceed further.
Keep the stand mixer running and slowly add sugar to it.
Keep whisking until it turns into a thick and shiny fluff.
Pour in oil mixture. Fold the mix until it is well blended with aquafaba.
Spoon the dry sifted ingredients into this mix. Fold in gently.
Fold and mix until it forms a smooth and lump-free batter.
Pour the batter into the greased pan.
Tap the pan to release the trapped air. Sprinkle some extra chocolate chips on top.
Bake for 20 - 22 minutes or until the toothpick comes out with a few crumbs attached.
Allow the baked brownie to cool in the pan for 5-10 minutes. Then lift the brownie from the parchment paper and remove it from its pan.
Set it on a wire rack to cool completely.
Cut the brownie into 9 equal parts.
Enjoy topped with your favorite ice cream and a drizzle of chocolate.
