The Best Chocolate Crinkle Cookie Recipe

To a medium-sized mixing bowl, combine the cocoa powder, cacao powder, sugars and olive oil. Whisk or stir till combined. Add in either the flax eggs or regular eggs and stir till combined. Once combined, add in the vanilla.
Into another medium-sized mixing bowl, combine the flour, baking powder and salt. Stir till combined.
Add the dry ingredients to the wet ingredients bowl and stir just till well combined.
Cover with a cloth, wax paper or cling film and place in the fridge for at least 3 hours but can be left overnight.
Preheat the oven to 350F and line two large baking sheets with parchment paper and set aside.
Now, roll the dough into around 1 tbsp. balls and toss them into icing sugar. Coat them well and begin placing each ball on the pre-lined baking sheets. You should be able to fit 8 cookies per sheet.
Bake for 10 minutes and cool on the baking sheet for 5 minutes before transferring them to a cooling rack.
