Preheat the oven to 375º.
Make the dough:
Place the sugar, oil, vanilla and eggs in a large mixing bowl and whisk until smooth. In a separate bowl, whisk together the flour and baking powder to combine.
Stir the dry ingredients into the sugar mixture and knead until a smooth dough forms. The dough should not be sticky, but it will be a bit oily.
Pinch off a 2-tablespoon sized ball of dough. Roll the ball into a 12-inch long rope and fold in half to have the ends meet. Turn both ends in opposite directions to twist the rope, then meet both ends and press to form a circle. Repeat with remaining dough.
Make the dipping sugar:
In a small bowl, whisk together the sugar and cinnamon. Press each cookie in the cinnamon sugar to coat and place on two baking sheets, 1-inch apart from one another.
Bake until lightly golden, about 15 minutes. Remove both trays and turn off the oven. Transfer all the cookies to 1 baking sheet (they can overlap and stack) and return to the oven. Let sit in the oven until dry, at least 20 minutes, then remove and let cool completely.
Serve immediately, or store in an airtight container for up to 2 days.
