Combine Ingredients: Start by whisking together the spice cake mix and cinnamon in a large bowl. Then, stir in the oil and eggs until the mixture is thoroughly combined.

Chill Dough: Cover the bowl with plastic wrap and place it in the refrigerator for a few hours to chill, which will make the dough easier to handle.

Preheat Oven: Set your oven to 350°F (175°C) to preheat.

Prepare Baking Sheets: Line your baking sheets with parchment paper to prevent sticking and ensure easy cleanup.

Shape Cookies: Scoop the dough by tablespoonfuls, rolling each into a ball. Next, roll each ball in powdered sugar to coat them evenly.

Bake Cookies: Arrange the coated dough balls on the prepared baking sheets, leaving space between them for expansion. Bake for about 10 minutes, or until the cookies are set and exhibit their characteristic crinkles.

Cool: Allow the cookies to cool on the baking sheets for a few minutes before transferring them to wire racks to cool completely.

Enjoy these Cinnamon Crinkle Cookies as a delightful conclusion to any meal or as a charming snack to brighten your day. Their easy preparation and irresistible taste make them a perfect choice for bakers of all levels looking to add a touch of sweetness and spice to their culinary repertoire.
