Cornflake Chocolate Chip Marshmallow Cookies

My kind of cookie!


Makes fifteen to twenty

Ingredients
16 tbsp. (2 sticks) room-temperature butter
1¼ c. granulated sugar
2/3 c. light brown sugar, tightly packed
1 egg
½ tsp. vanilla extract
1½ c. flour
½ tsp. baking powder
½ tsp. baking soda
1½ tsp. kosher salt
3 c. Cornflake Crunch
2/3 c. mini chocolate chips
1¼ c. mini marshmallows

1. In the bowl of a stand mixer fitted with the paddle attachment, combine butter and sugars; cream together on medium-high 2-3 minutes. With a spatula, scrape down sides of bowl, then add egg and vanilla and beat 7-8 minutes.

2. Reduce speed to low; add flour, baking powder and soda, and salt. Mix just until dough comes together, no longer than 1 minute. (Do not walk away from the machine during this step or risk overmixing.) Scrape down sides of bowl.

3. Still on low speed, paddle in cornflakes and chips until just incorporated, about 30-45 seconds. Paddle in marshmallows.

4. Line a sheet pan with parchment paper. Using a 2-oz. ice cream scoop, portion 1/3 c. dough at a time onto pan. Pat tops of dough domes flat. Wrap pan tightly in plastic wrap and refrigerate for at least 1 hour or up to 1 week. (Do not bake room-temperature disks — they will not hold their shape.)

5. Heat oven to 375°. On a parchment- or Silpat-lined sheet pan, arrange chilled disks a minimum of 4 inches apart. Bake 18 minutes, until cookies are browned on edges and just beginning to brown toward the center. Cookies will puff, crackle, and spread. Leave them in oven for another minute or so if they still seem pale and doughy on the surface.
