01 - Preheat oven to 350°F and 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 softened butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Blend in vanilla extract until fully combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Avoid overmixing.
06 - Gently fold in the pastel sprinkles and candy-coated chocolates using a spatula until evenly distributed.
07 - Scoop tablespoon-sized portions of dough onto prepared baking sheets, spacing each mound 2 inches apart.
08 - Bake for 9 to 11 minutes, or until the edges are just golden and centers remain soft. Do not overbake to maintain a tender cookie.
09 - Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
