1Cream the cold, cubed butter with the brown and white sugars on medium-high for 3-4 minutes until it forms a grainy, textured paste.
2Mix in the cold egg and vanilla extract just until combined. Do not over-mix.
3Add the flour, baking soda, baking powder, and salt. Mix on low just until the flour streaks disappear.
4Gently fold in the white chocolate chips and 1/2 cup (15g) of cracked cereal squares.
5Divide into massive 160g+ portions. Shape them into tall, rough cylinders (like a soda can) rather than perfect round balls.
6Chill the dough cylinders in the fridge for 30–60 minutes (or freezer for 30 minutes) until firm but not rock-hard.
7Preheat your oven to 350°F
8Place only 2 to 3 giant cookies per baking sheet to allow room for a massive spread.
9Bake for 15-17 minutes, OR UNTIL THE SIDES ARE GOLDEN BROWN.

Tips
If cookies aren't golden brown after 15 minutes, bake for a little longer.
If cookies are too tall, not baked enough, or too "cake-like", you can slightly bang them onto a counter when they come out of the oven to collapse the middle and create ripples.
