  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 2/3 cup butter, softened about 10.67 Tablespoons
  • 3/4 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 3/4 cup chocolate chips or chopped chocolate bar
  • 1/4 cup mini marshmallows cut into small pieces
  • 1 teaspoon sea salt for topping, or add 1/4 teaspoon salt to batter


  • Preheat the oven to 350 degrees F.
  • Combine the flour, baking soda, and baking powder together in a large mixing bowl.
  • Mix the softened butter, granulated sugar, brown sugar, vanilla extract, and egg together in a separate bowl.
  • Pour the liquid ingredients into the dry ingredients and mix until just well combined.
  • Mix in the chocolate chips.
  • Chill the dough for about 1 hour (optional).
  • Spoon the cookie dough on to baking sheets to create 18-20 cookies.
  • Add the marshmallow pieces to each cookie (about 2-3 pieces each).
  • Sprinkle each cookie with a little bit of salt.
  • Bake each batch for 10-12 minutes.


  • Don't over mix the dough. Mix until everything is just evenly combined!
  • Chill the cookie dough. This is optional if you're in a hurry, but it's best for keeping the structure of the cookies and letting the flavors "marinate"!
  • Sprinkle a little bit of graham cracker crumbs over each cookie to really add that s'more flavor!
  • Don't over bake (unless you love crispy cookies)! If you're looking for a perfectly chewy, gooey chocolate chip cookie texture, then bake for 10-12 minutes at 350 degrees F.
