120g aquafaba (aka liquid from a tin of chickpeas)
160g granulated sugar
120g light brown sugar
1/2 tbsp vanilla extract
113g salted vegan butter
140g vegan dark chocolate (or more vegan choc chips)
46g Dutch process cocoa
160g all purpose flour
1/2 tsp salt
100g vegan chocolate chips (or chocolate chunks)
1/2–3/4cup biscoff spread
11–12 biscoff cookies
Instructions
Preheat oven to 180°C/356°F. Line a 9-inch or 8-inch square baking pan with foil. Lightly grease the foil with vegan butter.
Brownie Batter: Sift all-purpose flour, Dutch-process cocoa and salt. In another bowl, add aquafaba, granulated sugar and brown sugar. Whisk with a handheld whisk for around 3-9 minutes or until it becomes white in colour and thick – kinda like meringue! Using the bain-marie method, melt salted vegan butter and vegan dark chocolate. Pour melted chocolate mixture into the aquafaba mixture, and add in vanilla extract. Fold until well combined. Fold in the dry ingredients until almost combined. Finally, add in the vegan chocolate chips and break 6 biscoff biscuits into the bowl, and fold together until completely combined!
The Biscoff: Pour into a pre-prepared baking pan. Using an angled palette knife or the back of a spoon, even out the batter. Dollop biscoff spread all over the batter, and swirl with a chopstick (or knife). It’ll be a little tricky because of the biscoff cookies, but keep going until you have pretty swirls. With an offset spatula carefully spread the batter into an even layer. Break 5 more biscoff biscuits over the batter.
Baking: Bake for 28-30 minutes. You’re going to want to keep an eye on these brownies, as everyone’s oven is different. I’d advise checking them after they hit the 28-minute mark. Then, after every 2 minutes check if they’re done by inserting a toothpick – it should come out with a little batter and a couple of crumbs.
Final touches: Remove brownies from the oven, and allow them to cool in the baking pan until completely cooled. Slice and serve!
