Grease and line a large baking tray with baking paper
Pre-heat the oven to 160°C fan (180°C conventional)
Sieve the flour into a bowl
Beat together the sugar and butter until the mix is light and fluffy
Gradually beat in the aquafaba, maple syrup, nut butter and vanilla extract (don't worry if the mix starts to curdle slightly, it should un-curdle as soon as more dry ingredients are mixed in later)
Mix in with the flour and pinch of salt
Using a spoon (or ice cream scoop) make 12 balls out of the mix
Put the balls onto a tray, evenly spread out, and flatten them slightly with the back of a fork
Bake the cookies for approx. 18 minutes, until they are browned and slightly golden
Leave them to cool slightly on the tray and then place them on a wire rack to finish cooling
Store at room temperature in a cake tin or tupperware
