Preheat oven to 325 degrees.
In the bowl of a mixer cream together butter, both sugars, and vanilla until light and fluffy.
Add one egg at a time, mixing well between each egg.
When the mixture has become light and airy slowly add in the flour, salt, baking powder, and baking soda. Mix well.
Fold in the oats and colored sprinkles.
Roll dough into ¾ inch balls and place onto a baking sheet lined with parchment paper, approximately 1”-2” apart from each other. (For extra color on the top of your cookies you can dip the top of the dough ball into some sprinkles and gently pat them into the dough.)
Bake for 6-8 minutes, or until the edges are very lightly golden and the center is just set.
Remove from the oven and let cool.
