Preheat your oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper and set it aside.
In a large mixing bowl, cream the softened butter and sugar together until light and fluffy. This should take about 2-3 minutes using a hand mixer or stand mixer.
Add in the eggs, one at a time, mixing well after each addition.
Add in the vanilla extract, and mix until combined.
In a separate mixing bowl, whisk together the cake mix and other dry ingredients.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the rainbow sprinkles, using a spatula.
Use a cookie scoop or spoon to drop the dough onto the lined baking sheet, leaving about 2 inches of space between each cookie.
Bake the cookies for 10-12 minutes or until the edges are golden brown.
Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Store the cooled cookies in an airtight container at room temperature for up to 5 days.
