Buttery and crispy are the best way to describe these cornflake cookies. They turn out thin and crunchy and are always a favorite at my house.


  • 1 cup (8 ounces) unsalted butter, room temperature
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 11/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon cream of tartar
  • 1/2 teaspoon salt
  • 2 cups cornflakes


  1. Preheat the oven to 350 degrees F. Line two sheet pans with parchment.
  2. In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar until light and fluffy. Mix in the vanilla extract and egg until fully incorporated.
  3. In a medium bowl, combine the flour, baking soda, cream of tartar and salt. Fold the dry ingredients into the wet ingredients. Stir in the cornflakes.
  4. Drop the dough by the scant 1/4-cup spacing 3-inches apart on the sheet pan. Bake for 15-17 minutes until the cookies are golden brown. Cool on the sheet pan for 5 minutes before transferring to a wire rack to cool completely.
  5. Store in an airtight container.
