Ingredients
Method
- In a large bowl, whisk together 1 cup granulated sugar, oil, and cocoa powder until smooth and glossy, about 1 minute.
- Beat in eggs one at a time, then stir in vanilla extract.
- In a separate bowl, whisk flour, baking powder, and salt. Fold into chocolate mixture until just combined.
- Cover tightly and refrigerate at least 3 hours or overnight.
- Preheat oven to 350°F (175°C). Line baking sheets with parchment. Place 1/2 cup granulated sugar and 1 cup powdered sugar in separate shallow bowls.
- Scoop 1.5 tablespoons cold dough, roll into smooth balls. Roll first in granulated sugar, then generously in powdered sugar.
- Place 2 inches apart on prepared sheets. Bake 10-12 minutes until puffed and deeply cracked with set edges.
- Cool on baking sheet 5 minutes, then transfer to wire rack.
Notes
Don't skip the chill — cold dough is essential for deep cracks. Be generous with the powdered sugar coating. Store in airtight container up to 1 week, or freeze up to 3 months.
