Step 1: Prepare Your Ingredients - Gather all your ingredients and ensure the unsweetened chocolate is melted and cooled.
Step 2: Mix the Wet Ingredients - Combine vegetable oil, melted chocolate, and granulated sugar in a mixing bowl. Whisk together, then add vanilla extract and eggs one at a time, mixing well.
Step 3: Combine the Dry Ingredients - In a separate bowl, whisk together flour, baking powder, and salt. Gradually add to the wet ingredients, stirring until just combined.
Step 4: Chill the Dough - Cover the bowl with plastic wrap and refrigerate for about 30 minutes.
Step 5: Preheat the Oven - Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 7: Roll in Powdered Sugar - Roll each dough ball in powdered sugar until generously coated.
Step 8: Bake the Cookies - Place dough balls on the baking sheet and bake for 10-12 minutes until crinkled on top and slightly underbaked in the middle.
Step 9: Cool and Enjoy - Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
