Preheat oven to 350°F and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, cornstarch, and salt. Set aside.
In a separate large bowl, beat together the butter, brown sugar, and sugar.
Add the egg and vanilla and beat to combine.
Add the dry ingredients to the wet ingredients and mix until a dough forms.
Pour in the M&Ms, chocolate chips, white chocolate chips, pretzels, potato chips, and sprinkles. Fold or stir to combine.
Scoop heaping tablespoons of dough and roll into a ball between your hands. Place each dough ball on the prepared baking sheet. Press each dough ball down to flatten slightly.
Place the cookies in the preheated oven and bake for 8 to 10 minutes, until the bottom edges are golden brown.
Allow the cookies to cool on the baking sheet for three to four minutes, then transfer to a wire cooling rack to cool completely.
