Cornflake Cookies (Hawaiʻi Local Christmas Tin Cookies)

Ingredients

Equipment Needed

• •Stand mixer or sturdy hand mixer
• •2-tablespoon cookie scoop
• •Two rimmed half-sheet pans
• •Cooling racks
• •Metal cookie tin with wax paper

Instructions

1. 1

   Heat the oven

   Set the oven to 350F with racks in the upper and lower thirds. Line two half-sheet pans with parchment. Set out cooling racks and the cookie tin now, because once the baking starts the house moves fast, same as every auntie's kitchen before the exchange.

2. 2

   Break the crunch

   Lightly crush the 2 cups cornflakes for the dough in your hands, leaving some flakes big enough to show. Do the same with the 1 cup for coating and keep it in a separate shallow bowl. Leave the crispy rice cereal whole so it gives that small crackle under your teeth.

   No turn the cornflakes to dust. You want ridges and crags on the cookie, not cereal flour.
3. 3

   Cream the butter

   Beat the softened butter, granulated sugar, and brown sugar on medium speed for 2 to 3 minutes, until lighter and soft around the edges of the bowl. It doesn't need to look like cake batter. It should look creamy, sandy, and ready to hold all that cereal.

4. 4

   Add egg and vanilla

   Beat in the egg until the dough turns smooth, then beat in the vanilla. Scrape the bowl well. Little steps like that are where the cookie stays even, no dry pocket hiding at the bottom.

5. 5

   Mix the dry

   Whisk the flour, baking soda, baking powder, and salt together, then add them to the butter mixture on low speed. Stop when the last flour streaks are almost gone. Don't beat it hard now, or the cookie turns tough and no auntie is putting that in the good tin.

6. 6

   Fold the cereal

   Fold in the 2 cups crushed cornflakes, the crispy rice cereal, and the nuts if you're using them. Use a sturdy spatula and turn from the bottom until the dough is full of crunch in every scoop. It will look crowded. That's the point.

7. 7

   Scoop and coat

   Scoop heaping tablespoons of dough, roll each one gently in the reserved crushed cornflakes, and set them 2 inches apart on the pans. Press each mound just a little so it sits steady, not flat. The coating should cling in rough flakes around the outside.

8. 8

   Bake to crackly

   Bake 10 to 12 minutes, rotating the pans halfway, until the edges turn light amber, the tops look dry, and the cornflake tips are toasted gold. The centers will still feel a touch soft when you lift the pan. Trust that. They finish setting as they cool.

9. 9

   Cool and tin

   Let the cookies sit on the pan for 5 minutes, then move them to racks until fully cool. Pack them into a metal tin lined with wax paper, layers of cookies and paper, cookies and paper. That's how they keep their crackle, and that's how they travel to the next kitchen.

Chef Tips

• •Use cereal that still snaps when you bite it. If it's a little old but still crisp, eat what you have. If it's flat and leathery, save it for something else and don't blame the cookie.
• •Butter temperature matters more than fancy tools. Soft means your finger leaves a dent but the butter still holds its shape. Melted butter makes the cookies spread thin.
• •Macadamia nuts feel right for Hawaiʻi, but walnuts are what plenty aunties used because that was what sat in the pantry. Keeper, not gatekeeper.
• •Cool the cookies completely before the tin closes. Hawaiʻi humidity is real, and warm cookies trapped in a closed tin lose their crackle fast.

Advance Preparation

• •The dough can be mixed and chilled up to 24 hours ahead. Let it sit at room temperature for 10 minutes before scooping so the cereal doesn't crush under the scoop.
• •Scooped dough balls can be frozen for up to 1 month. Bake from frozen at 350F, adding 1 to 2 minutes as needed.
• •Baked cookies keep 5 to 7 days in a tightly closed tin. If they soften, set them on a pan in a 300F oven for 4 to 5 minutes, then cool fully before packing again.
