Ingredients

Cookies:

  • ½ cup salted butter room temperature
  • ½ cup white granulated sugar
  • ½ cup light brown sugar
  • 1 large egg
  • 1 1/2 cups all-purpose flour
  • ½ cup finely crushed Oreos
  • 1/2 teaspoon baking soda
  • ½ teaspoon baking powder

Frosting:

  • ½ cup salted butter room temperature
  • 1 cup powdered sugar
  • ½ cup finely crushed Oreos

Instructions

  • Preheat your oven to 350°F.
  • In a large mixing bowl, beat the butter, granulated sugar, and brown sugar together until smooth and creamy.
  • Add the egg and beat until fully combined.
  • Reduce the mixer speed and mix in the flour, crushed Oreos, baking soda, and baking powder just until no dry streaks remain.
  • Divide the dough into 12 portions. Roll into balls and gently flatten into thick discs.
  • Chill the shaped dough balls in the refrigerator for 30 minutes. This step helps the cookies hold their shape and bake up soft and chewy.
  • Bake for 11 minutes, until the edges are set and the centers still look slightly soft.
  • Let the cookies cool on the pan for several minutes before transferring to a wire rack. Cool completely before frosting.
  • For the frosting, beat the butter, powdered sugar, and finely crushed Oreos together until smooth and fluffy. Spread or pipe onto cooled cookies.

Notes

  • Finely crush Oreos for smooth frosting.
  • Chill dough for 30 minutes before baking to prevent overspreading.
  • Add ½ teaspoon salt if using unsalted butter.
  • Freeze unfrosted cookies up to 2 months.
