Ingredients

Scale
  • 2 1/4 cups all-purpose flour (spooned and leveled)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup unsalted butter, softened
  • 3/4 cup packed brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup M&Ms (regular or mini; peanut optional)
  • 1 cup unsalted butter, softened (for frosting)
  • 3 to 3 1/2 cups powdered sugar
  • 2 teaspoons vanilla extract (for frosting)
  • 2 to 3 tablespoons whole milk
  • Pinch of salt (for frosting)
  • Additional M&Ms for decorating

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9-inch round pan with parchment paper or grease it well.
  2. In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter with brown sugar and granulated sugar until light and fluffy, about 3-4 minutes.
  4. Beat in the egg and vanilla extract until fully combined.
  5. Gradually add the flour mixture to the wet ingredients, mixing on low speed until just combined. Avoid overmixing.
  6. Fold in 1 cup of M&Ms, reserving some for decoration.
  7. Press the dough evenly into the prepared pan and press reserved M&Ms onto the surface.
  8. Bake for 25 to 30 minutes until edges are golden and a toothpick inserted near the center comes out with a few moist crumbs.
  9. Cool the cookie cake completely in the pan on a wire rack for at least 30 minutes.
  10. Prepare frosting by beating softened butter with powdered sugar, vanilla extract, milk, and a pinch of salt until light and creamy. Adjust milk or powdered sugar for desired consistency.
  11. Spread frosting evenly over the cooled cookie cake and decorate with additional M&Ms arranged in a flag pattern or preferred design.
  12. Refrigerate for 15-20 minutes to set the frosting if desired, then slice and serve.

Notes

Measure flour correctly by spooning and leveling to avoid dense cookies. Beat butter and sugars until light and fluffy for tender texture. Cool cookie completely before frosting to prevent melting. Adjust frosting consistency by adding milk or powdered sugar. Tent with foil if edges brown too fast.
