01 - Preheat oven to 350°F. Line two baking sheets with parchment paper for easy cleanup and to prevent sticking.
02 - In a medium bowl, whisk together all-purpose flour, baking soda, and salt until well blended. Set aside for later use.
03 - In a large bowl, beat softened butter, light brown sugar, and granulated sugar together until mixture appears light and fluffy, approximately 2-3 minutes.
04 - Beat in eggs one at a time, ensuring each is fully incorporated before adding the next. Mix in vanilla extract until combined.
05 - Gradually add the flour mixture to the wet ingredients, mixing on low speed just until flour streaks disappear. Avoid overmixing to prevent tough cookies.
06 - Gently fold M&M candies and white chocolate chips into the dough using a spatula, distributing them evenly throughout.
07 - Using a medium cookie scoop or tablespoon, drop dough balls onto prepared baking sheets, spacing 2 inches apart. Press extra M&M candies and optional bunny decorations onto the tops.
08 - Bake for 9-11 minutes until edges appear set while centers remain slightly soft and underbaked for optimal chewiness.
09 - Let cookies rest on baking sheets for 5 minutes to firm up, then transfer to a wire rack to cool completely before serving.
