Cornflake Cookies

These are the best cornflake cookies! They have a buttery, caramel flavor, with chewy oatmeal-cookie-like centers, and a nice crunch from the cornflakes, all sprinkled with flaky sea salt.

Ingredients
 

  • 1 ¾ cups (218 g) all-purpose flour, spooned and leveled
  • ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (224 g) salted butter, softened
  • 1 cup (220 g) light brown sugar, packed
  • ¼ cup  (50 g) granulated white sugar
  • 2 egg yolks, at room temperature
  • 1 tablespoon (15 ml) vanilla extract
  • 1 ½ cups (120 g) old fashioned oats
  • 1 ½ cups (60 g) cornflakes
  • flaky sea salt for sprinkling

Instructions
 

  • Preheat the oven to 350 degrees. Line two baking sheets with parchment paper and set aside.
  • In a medium bowl, whisk the flour, baking powder, baking soda and salt together. Then set aside the dry ingredients.
    1 ¾ cups (218 g) all-purpose flour, spooned and leveled, ½ teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt
  • In a large bowl, cream the butter, brown sugar and granulated white sugar together with an electric hand mixer on high speed until light and fluffy, 2-3 minutes.
    (You can also use a stand mixer fit with a paddle attachment if you would rather.)
    1 cup (224 g) salted butter, softened, 1 cup (220 g) light brown sugar, packed, ¼ cup  (50 g) granulated white sugar
  • Add in the egg yolks and vanilla extract and mix on medium speed until pale in color and fluffy, 1-2 minutes. (Scrape the sides of the bowl as necessary.)
    2 egg yolks, at room temperature, 1 tablespoon (15 ml) vanilla extract
  • Add the dry ingredients to the wet ingredients and mix on low speed just until combined.
  • Mix the oats and cornflakes into the dough with a rubber spatula.
    1 ½ cups (120 g) old fashioned oats, 1 ½ cups (60 g) cornflakes
  • Scoop the dough with a large, 2 tablespoon capacity cookie scoop. Arrange the cookie dough balls 2 inches apart on a prepared baking sheet. Bake the cookies for 10-12 minutes.
    (10 minutes gives you chewy cookies, and 12 will give you crispier cookies.)
  • After baking, let the cookies cool on the cookie sheet for five minutes, then transfer them to a wire rack to completely cool.
    When the cookies are straight out of the oven, scoot a large circular cookie cutter around them to give them a perfect circular shape. While they're cooling, sprinkle flaky sea salt on top of the cookies.
