250 grams flour
150 grams sugar
120 ml vegetable oil
2 levelled tablespoons unsweetened cocoa powder
3 teaspoons liquid red food colouring
1 teaspoon baking powder
1 teaspoon apple cider vinegar
1 teaspoon vanilla
In a small bowl, mix together the cocoa powder, liquid food colouring, vinegar and vanilla, and whisk until well combined. Sift the flour and the baking powder and set aside. In a large bowl, beat the egg with the sugar and oil, on high, until the batter becomes lighter in colour and thick (it will take a few minutes). Add the cocoa mix and blend really well, until the colour is equally distributed.
Finally, add the flour mixture in a few additions, until you get a shiny and thick cookie batter that doesn't stick to your hands. Using a tablespoon or a small cookie scoop, take out portions of the batter, roll into balls and arrange on a cookie sheet lined with baking paper (you will get about 20 cookies). Bake them in a preheated oven, at 190˚C, for 8-9 minutes (mine were done after 9 minutes).
