01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together all-purpose flour, baking soda, and salt. Set aside.
03 - In a large mixing bowl, beat the softened butter, granulated sugar, and light brown sugar using an electric mixer or stand mixer on medium speed until mixture is light and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time, beating well after each addition, then mix in vanilla extract.
05 - Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined. Do not overmix.
06 - Using a spatula, gently fold in pastel-colored sprinkles and candy-coated chocolates evenly throughout the dough.
07 - Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing each portion approximately 2 inches apart.
08 - Bake for 9 to 11 minutes, until edges are just golden. For a soft texture, avoid overbaking.
09 - Allow cookies to cool on baking sheets for 5 minutes before transferring to a wire rack until completely cooled.
