Chocolate Crinkle Cookies

Method

1. 1In a large bowl, whisk together cacao powder, sugar, eggs, vanilla extract, instant coffee, oil and salt until smooth and well combined.
2. 2Add the flour and baking powder, then fold until just combined into a thick, sticky dough.
3. 3Cover and refrigerate for at least 6 hours, or overnight – this makes the dough easier to handle and improves texture.
4. 4Preheat oven to 170°C (340°F). Line a baking tray with parchment paper.
5. 5Roll the chilled dough into walnut-sized balls, then roll generously in icing sugar to coat.
6. 6Place on the prepared tray with space between each cookie.
7. 7Bake for 15 minutes until the cookies have spread and cracked on top, but are still soft in the centre.
8. 8Let cool on the tray for a few minutes, then transfer to a wire rack. The cookies will firm up as they cool.
