These unique cookies have a combination of ingredients that help to create a surprisingly crisp cookie with a soft center. Go ahead, make them - you'll love them!
Preheat the oven to 350°F. Line a baking sheet with parchment paper and set aside.
Mix the dry ingredients: Cream the butter with granulated sugar and brown sugar until light and fluffy, 3 minutes. Add eggs one at a time, mixing until incorporated after each egg. Add vanilla extract and mix. The mixture may look curdled after the vanilla, but this is normal.
16 tablespoons (2 sticks) unsalted butter, 1 cup granulated sugar, 1 cup light brown sugar, 2 large eggs, 1 teaspoon vanilla extract
Add the dry ingredients: To the mixer, add the flour, baking soda, baking powder, and salt, and mix. Add the rolled oats, cornflakes, and chopped peanuts, and mix briefly until everything is incorporated.
2 ⅓ cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, ½ teaspoon kosher salt, 1 cup rolled oats, 1 cup cornflakes, 1 cup peanuts
Form the cookies: Using a #40 cookie scoop (about 2 tablespoons), drop the cookies onto the prepared baking sheet.
Bake in a preheated 350°F oven, one pan at a time, for 8-12 minutes, until slightly puffed and golden brown. Remove from the oven and cool on the pan for 5 minutes, then transfer to a cooling rack to cool completely.
