Beat cubed cold butter and granulated sugar with a stand mixer on high speed for 2–3 minutes until light and fluffy, forming a smooth base.

Mix in vanilla extract and continue beating for an additional minute to enhance flavor depth.
06 -
On medium mixer speed, gradually add dry ingredients to wet mixture, mixing just until flour streaks disappear to maintain softness.
07 -
Cover dough and refrigerate for 30 minutes to firm up, promoting thicker, chewier cookies.
08 -
Preheat oven to 215°C (420°F). Line two baking sheets with parchment paper or silicone mats to prevent sticking and ensure even baking.

Divide chilled dough equally into three bowls. Add one neon gel food coloring to each and knead until color is evenly distributed and vibrant.
10 -
Pinch a tablespoon-sized portion from each colored dough, roll each into a ball, press together gently, and roll the combined mass into one large dough ball creating distinct swirls.
11 -
Roll each multi-hued dough ball first in white chocolate chips so they adhere well, then roll the edges in Halloween sprinkles for decorative effect.
12 -
Gently press each coated dough ball into a thick disk. Place on prepared baking sheets spaced 5 cm (2 inches) apart to allow proper rising and spreading.
13 -
Bake individually for 12 to 14 minutes, monitoring closely until edges turn golden while centers remain soft and pillowy.
14 -
Allow cookies to cool briefly on the baking sheet to set their shape, then transfer to a wire rack to cool completely preserving chewiness.
