Preheat the oven to 350 degrees Fahrenheit. Line two baking sheets with parchment paper and set aside.
02 -
Combine unsalted butter, dark brown sugar, and granulated sugar in a large mixing bowl. Using an electric mixer set to medium speed, blend for 2 minutes until the mixture appears light and fluffy.
03 -
Add egg yolks and vanilla extract to the bowl. Mix on medium speed until the mixture becomes pale and aerated, approximately 2 minutes.
04 -
Introduce all-purpose flour, baking soda, baking powder, and salt. Mix on low speed just until the dry ingredients are fully incorporated and no streaks of flour remain.
05 -
Gently fold in M&M's, white chocolate chips, chopped pretzel pieces, crushed potato chips, and sprinkles using a spatula until evenly distributed.
06 -
Scoop the dough onto the prepared baking sheets, placing six cookies per sheet. Bake for 10 to 12 minutes or until lightly golden at the edges.
07 -
If desired, immediately after baking, use a circular glass to gently shape each cookie for a uniform appearance. Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack.
08 -
Optionally, garnish with additional mix-ins while cookies are still warm. Serve when completely cooled.
