01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
03 - In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract until fully blended.
05 - Gradually add the dry ingredients to the butter mixture, mixing until just combined and no dry streaks remain.
06 - Gently fold in the pastel sprinkles and candy-coated chocolates using a spatula.
07 - Portion tablespoon-sized amounts of dough onto the prepared baking sheets, spacing each portion 2 inches apart.
08 - Bake for 9–11 minutes until the edges are set and lightly golden. Avoid overbaking for a soft texture.
09 - Allow cookies to cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
