Ingredients

Wet Ingredients

  • 1/2 cup butter
  • 3/4 cup packed brown sugar
  • 1/2 cup sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 cup all-purpose flour
  • 3/4 teaspoon salt
  • 1/2 teaspoon baking soda

Add-ins

  • 1 1/2 cups Rice Krispies cereal
  • 2/3 cup miniature marshmallows
  • 1/2 cup toffee bits
  • Flaky sea salt, optional for sprinkling


Instructions

  1. Brown the Butter: Place the butter in a small heavy saucepan and cook it over medium heat until it turns golden brown and develops a nutty aroma, about 5 to 7 minutes. Keep an eye on it to avoid burning, but a few browned bits add flavor. Remove from heat and let it cool slightly.
  2. Prepare the Cookie Dough: In a large bowl, beat together the browned butter, brown sugar, and sugar until well blended. Add the egg and vanilla extract and beat on low speed until combined.
  3. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, salt, and baking soda. Gradually add this dry mixture to the wet ingredients, mixing thoroughly to create the cookie dough.
  4. Fold in Add-ins: Gently stir the Rice Krispies cereal, miniature marshmallows, and toffee bits into the dough until evenly distributed.
  5. Shape and Bake: Preheat the oven to 350°F (175°C). Drop the dough by tablespoonfuls onto parchment-lined baking sheets, spacing them about 2 inches apart. Bake for 10 to 12 minutes, or until the cookies turn golden brown around the edges.
  6. Cool and Finish: Transfer the baked cookies to wire racks to cool completely. If desired, sprinkle them lightly with flaky sea salt to enhance the flavor.

Notes

  • Browning the butter adds a rich, nutty flavor that enhances these cookies.
  • Make sure the egg is at room temperature for better mixing and texture.
  • If you prefer softer marshmallows, fold them in gently to avoid breaking.
  • For extra crunch, toast toffee bits lightly before adding them.
  • Store cookies in an airtight container at room temperature for up to 5 days.
