Ingredients

Scale
  • 2 1/4 cups (280g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup (170g) unsalted butter, softened
  • 3/4 cup (150g) granulated sugar
  • 3/4 cup (165g) packed light brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 1/2 cups (270g) red, white, and blue M&Ms

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your star-shaped pan lightly with butter or non-stick spray, then line it with parchment paper for easier removal.
  2. In a large bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
  3. Using a hand or stand mixer, beat the softened unsalted butter, granulated sugar, and light brown sugar on medium speed until light and fluffy, about 3 to 4 minutes.
  4. Add the eggs one at a time, mixing well after each addition. Stir in the pure vanilla extract.
  5. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing.
  6. Gently fold in about 1 1/2 cups of red, white, and blue M&Ms with a spatula, reserving some for topping.
  7. Transfer the dough to the prepared star-shaped pan. Press the dough evenly into the pan and smooth the top. Sprinkle the reserved M&Ms on top and press gently.
  8. Bake for 18–22 minutes until edges are golden brown but the center is still slightly soft.
  9. Let the cookie cake cool in the pan on a wire rack for at least 30 minutes before removing.
  10. Carefully lift the cookie cake out using the parchment paper and slice into wedges or squares.

Notes

Use softened but not melted butter for best texture. Do not overmix the dough to avoid toughness. Press M&Ms gently on top after spreading dough for a glossy finish. If edges brown too fast, cover with foil halfway through baking. Let cookie cool completely in pan to prevent crumbling. For gluten-free, use almond flour or gluten-free flour blend. For dairy-free, substitute butter with plant-based spread and use dairy-free M&Ms.
