Preheat the oven to 350°F (175°C).
In a large bowl, whisk together the flour, baking soda, and salt.
In a separate bowl, cream together the softened butter, granulated sugar, and brown sugar.
Add the eggs and vanilla extract, and beat until well combined.
Gradually add the flour mixture to the butter mixture and mix until just combined.
Fold in the colorful sprinkles gently using a spatula.
Drop rounded tablespoons of dough onto lined baking sheets, giving space between each cookie.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Allow cookies to cool on baking sheets for 5 minutes before transferring to a wire rack.
