Preheat your oven to 350°F (180°C). This ensures that your cookies bake evenly.
Line 2 rimmed baking sheets with parchment paper. This is crucial as it prevents the cookies from sticking and makes for easy cleanup.
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and both sugars together until fluffy, about 3 to 4 minutes. You want it to be light and creamy, which adds air to the cookies.
Add the eggs, one at a time, beating until fully combined after each addition. This helps to incorporate air and gives the cookies their structure.
Beat in the vanilla extract. This will enhance the overall flavor of the cookies, making them even more delicious.
In a separate medium bowl, whisk together the flour, baking powder, salt, cardamom, and baking soda. This keeps the dry ingredients evenly distributed.
With the mixer on low speed, gradually add the flour mixture to the butter mixture. Beat until just combined. You don’t want to overmix at this stage.
Add the white chocolate and finely crushed cereal to the dough, mixing until well combined. This step is where the cookies start to get exciting!
In a small shallow bowl, place the roughly crushed cereal. This will be used to roll the cookie dough balls for a fun texture.
Using a 2-tablespoon spring-loaded scoop, scoop the dough (about 53 grams each) and roll them into balls. Then roll each ball in the crushed cereal.
Place the dough balls about 1½ inches apart on the prepared pans. This is important to give them room to spread while baking.
Bake the cookies until they are slightly domed and thick, with edges that are golden brown, for about 10 to 11 minutes. Keep an eye on them to avoid overbaking!
Let them cool on the pans for 5 minutes before removing them to a wire rack to cool completely. This helps them set up while still warm.
Store the cookies in an airtight container for up to 5 days. But I doubt they’ll last that long!
