1. Prepare Oven and Baking Sheets:

Preheat the oven to 350°F (175°C).

Line two baking sheets with parchment paper. This will prevent the cookies from sticking and make cleanup easier.

2. Combine Ingredients: In a large bowl, combine the white cake mix, melted and cooled butter, ground cinnamon, and eggs.

Beat with a mixer (hand mixer or stand mixer) until well combined. The dough will be thick.

3. Stir in Sprinkles: Stir in the ¾ cup of colorful jimmy sprinkles until they are evenly distributed throughout the dough.

4. Scoop Dough onto Baking Sheets:

Drop the dough by rounded tablespoonfuls, about 2 inches apart, onto the prepared baking sheets.

Top with additional sprinkles, if desired.

5. Bake:

Bake for 10-12 minutes, or until the bottom edges of the cookies are lightly brown.

6. Cool: Let the cookies cool on the baking sheets for 2 minutes.

Transfer the cookies to a cooling rack to cool completely. Enjoy!
