1. Preheat your oven to 350°F and line baking sheets with parchment paper.

2. In a large mixing bowl, beat the softened butter, vegetable oil, granulated sugar, and brown sugar until smooth and creamy. Beat in the eggs and vanilla extract until well combined. In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and ground cinnamon. Gradually incorporate the dry ingredients into the wet ingredients, mixing until a soft dough forms. Cover the dough and chill it in the refrigerator for 30 minutes.

3. While the dough is chilling, prepare the cinnamon-sugar and powdered sugar coatings by mixing the granulated sugar and ground cinnamon in one bowl and adding the powdered sugar in another bowl.

4. Once the dough has chilled, use a cookie scoop or spoon to portion it into 1-inch balls. Roll each ball first in the cinnamon-sugar mixture, then in the powdered sugar until completely covered.

5. Arrange the coated cookie dough balls on the prepared baking sheets, spacing them about 2 inches apart. Bake for 10 to 12 minutes, or until the cookies are set and the tops are beautifully crinkled.

6. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
