01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - Whisk together all-purpose flour, baking soda, and salt in a medium bowl. Set aside.
03 - In a large mixing bowl, beat softened butter, granulated sugar, and light brown sugar with an electric mixer until light and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time to the butter mixture, beating well after each addition. Mix in vanilla extract.
05 - Gradually add the dry ingredients to the wet ingredients, mixing until just combined and no flour streaks remain.
06 - Fold in pastel-colored sprinkles and candy-coated chocolates with a spatula, distributing evenly throughout the dough.
07 - Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing each mound approximately 2 inches apart.
08 - Bake for 9 to 11 minutes, until the cookie edges are just golden. Avoid overbaking for a soft texture.
09 - Allow cookies to rest on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
