Preheat oven to 350°F. Line two baking sheets with parchment paper.
Cream butter, granulated sugar, and brown sugar until light and fluffy.
Beat in egg and vanilla extract.
Whisk together flour, baking soda, and salt, then gradually mix into the wet ingredients.
Gently fold in chocolate chips, crushed potato chips, pretzels, and holiday sprinkles.
Scoop dough into approximately 2-tablespoon balls and place 2 inches apart on prepared baking sheets.
Bake for 10–12 minutes, until edges are golden and centers are slightly soft.
Cool on baking sheets for 5 minutes, then transfer to a wire rack.
