S'Mores Cookie Bars

S’Mores Cookie Bars
Christine Larson, Mill Creek

All the goodness of s'mores in a simple to make cookie bar! These chocolate chip cookie bars have a graham cracker crust and gooey marshmallows on top. They are easy to make with no mixer required.

makes 24 bars

  • 11/2 cups graham cracker crumbs)
  • 4 tablespoons butter, melted
  • 21/8 cups flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 12 tablespoons butter, melted and cooled slightly
  • 1 cup brown sugar
  • 1/2 cup white sugar
  • 1 large egg, plus 1 large egg yolk
  • 2 teaspoons vanilla extract
  • 2 cups marshmallows, divided
  • 11/2 cups chocolate chips, divided

Preheat oven to 325 degrees. Adjust oven rack to lower-middle position. Line a 9 x 13-inch baking pan with foil, letting the excess hang over the edges of the pan by about 1 inch, so you can grab the edges and pull the bars from the pan after baking. Spray the foil lining with nonstick cooking spray.

Combine crushed graham crackers and 4 tablespoons melted butter in medium sized bowl. Stir with fork to combine. Pour graham mixture into prepared pan, covering the bottom of the pan, and press down firmly with hands. Refrigerate until ready to use.

Mix flour, salt and baking soda together in medium bowl; set aside.

Whisk the melted butter and sugars in a large bowl until combined. Add egg, egg yolk and vanilla, and mix well. Using a rubber spatula, fold dry ingredients into the egg mixture until just combined; do not overmix. Fold in 1 cup of marshmallows and 1 cup of chocolate chips.

Carefully spoon batter into prepared pan, placing dollops all around the prepared crust. Smooth the top with a pressing motion, using the spatula.

Sprinkle remaining marshmallows and chocolate chips on top and press in lightly.

Bake until the top of the bars is light golden brown, slightly firm to the touch, and edges start pulling away from sides of pan, 24 to 28 minutes. Cool on a wire rack to room temperature. Remove bars from the pan by lifting the foil overhang and transfer to a cutting board. Cut into squares and serve.

My family and I lovenuts - wold adding either pecans, walnuts or sliveted almonds make a significant change in the taste/cooking time of the recipe?

I think throwing in a cup of chopped nuts is a great idea. I don't think that would affect baking time.

Are the marshmallows miniature, small, medium or large.

Thank you

Mini marshmallows!

To arrive at "slightly firm to the touch" it took 22 more minutes of baking. Perhaps 325 degrees is too low?
