It’s a cookie that defies expectations and redefines what a cookie can be.

For the Cornflake Crunch:
Instructions:
The journey to these incredible cookies begin extracts with preparing the essential “Cornflake Crunch.” This component is the secret weapon, providing that signature crunch and malty depth.
Step 1: Prepare the Cornflake Crunch
In a large bowl, combine the 5 cups of cornflakes, 1/2 cup of malted milk powder, and 3 tablespoons of granulated sugar. Gently toss these ingredients together with your hands, trying to break up the cornflakes just slightly without turning them into dust. The goal is to coat the flakes with the malted milk powder and sugar. This mixture will be folded into the cookie dough later, and it’s this crunch that gives the cookies their distinctive character. Set this aside.
Step 2: Cream the Butter and Sugars
In a large mixing bowl (or the bowl of your stand mixer fitted with the paddle attachment), cream together the softened 1 cup of unsalted butter, 1 1/4 cups of granulated sugar, and 2/3 cup of packed light brown sugar. Beat on medium-high speed until the mixture is light, fluffy, and pnon-alcoholic ale in color. This process can take anywhere from 3 to 5 minutes. Don’t rush this step; creaming properly incorporates air, which contributes to the cookie’s texture. You want to ensure the sugars are well incorporated into the butter, creating a smooth and creamy base. Scrape down the sides of the bowl occasionally to make sure everything is evenly mixed.
Step 3: Add Wet Ingredients and Dry Ingredients
Next, beat in the 1 large egg and 1/2 teaspoon of vanilla extract until just combined. The mixture might look a little curdled at this stage, which is perfectly normal. In a separate medium bowl, whisk together the 1 1/2 cups of all-purpose flour, 1/2 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1 1/2 teaspoons of salt. This dry ingredient mixture provides the structure and leavening for our cookies. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough at this stage; overmixing can lead to tough cookies. Stop mixing as soon as you no longer see streaks of flour.
Step 4: Fold in the “Stars” of the Show
Now comes the exciting part: incorporating the “stars” of this cookie. Gently fold in the 3 cups of prepared Cornflake Crunch, the 2/3 cup of mini chocolate chips, and 1 1/4 cups of mini marshmallows into the cookie dough. Use a spatula or wooden spoon for this step, mixing just enough to distribute these delicious additions evenly throughout the dough. You want to see those delightful bits suspended in the cookie dough, promising bursts of texture and flavor in every bite. Again, avoid overmixing.
Step 5: Shape and Bake the Cookies
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Line baking sheets with parchment paper. I like to use an ice cream scoop or a large spoon to portion out the dough. For large, bakery-style cookies, aim for about 1/4 cup of dough per cookie. Roll each portion loosely into a ball and place them on the prepared baking sheets, leaving about 2 inches between each cookie to allow for spreading. These cookies spread quite a bit, so don’t overcrowd your baking sheets. Bake for 10-12 minutes, or until the edges are golden brown and the centers still look slightly soft and underdone. The marshmallows will puff up and become delightfully gooey.
Step 6: Cool and Enjoy!
Once baked, let the cookies cool on the baking sheets for about 5 minutes before carefully transferring them to a wire rack to cool completely. This resting period allows the cookies to set up properly. The centers will continue to cook slightly as they cool, achieving that perfect chewy texture. You’ll be tempted to eat them warm, and while they are divine that way, they also hold up beautifully once fully cooled. Store any leftover cookies in an airtight container at room temperature for up to 3 days. Prepare yourself for compliments, because these cookies are truly a showstopper!

Frequently Asked Questions:
Can I make these cookies ahead of time?
Yes, absolutely! The cookie dough can be chilled for up to 3 days before baking, which actually helps to deepen the flavors. Once baked, the cookies will stay fresh in an airtight container at room temperature for about 3-4 days. For longer storage, you can freeze baked cookies individually wrapped in plastic wrap and then placed in a freezer-safe bag for up to 3 months.
What kind of marshmallows work best?
The origin extractal recipe calls for large marshmallows, which melt into those delightful gooey pockets. You can also use mini marshmallows, though they will distribute more evenly throughout the cookie rather than creating large, distinct molten centers. If you prefer a less gooey cookie, you can reduce the amount of marshmallows slightly.
Are there any variations I can try?
Definitely! For a twist, you could try using different types of chocolate chips, like dark or white chocolate. Some bakers have also experimented with adding a pinch of cinnamon to the cornflake mixture for an extra layer of warmth. You could even try adding a tablespoon of malted milk powder to the dry ingredients for a more complex, malty flavor profile.
