Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly and achieve that perfect golden-brown color.
In a large mixing bowl, combine the melted unsalted butter, packed brown sugar, and granulated sugar. Whisk together until smooth. Add the eggs, one at a time, and then stir in the vanilla extract until well blended.
In a separate bowl, whisk together the salt, baking soda, and all-purpose flour. Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix, as this can lead to tough cookies.
Gently fold in the chocolate chips, M&Ms, chopped Crunch Bars, Kit Kats, and Snickers until evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto a baking sheet lined with parchment paper, leaving enough space between each cookie to allow for spreading.
Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked; they will continue to cook as they cool.
Remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy the cookies warm or store them for later!
