S’mores are a classic summer treat, with their melty chocolate and gooey marshmallow, plus the crunch of a graham cracker. If we’re being honest, though, s’mores are not the most convenient to make. Sometimes the weather isn’t right for a bonfire, or you don’t want to deal with the bugs. Plus, without a gas fire pit, it can be time consuming just to prep for your s’mores. This summer, I’ve been whipping up these s’mores cookie bars and they’re every bit as delicious as our summertime favorite, without the hassle. All the flavors of a s’more, made in the air conditioning!
For this recipe, I really prefer milk chocolate chips instead of semi-sweet because it tastes closer to an actual s’more, but it’s fine to use if that’s what you have on hand. Dark chocolate chips would be delicious, too!
S’mores Cookie Bars
- 2 sticks butter, about 80% melted
- 1 cup white sugar
- 1/3 cup brown sugar
- 2 eggs, separated
- 2 tsp. vanilla
- 2 3/4 cups all-purpose flour
- 1/2 tsp. salt
- 1 tsp. baking soda
- 1 cup chocolate chips
- 1 cup marshmallows
Preheat the oven to 350 degrees. Grease a 13×9 inch pan. It will look like the dough is spread too thin, but will puff up a little as it bakes.
Start by adding the butter and sugars to a large mixing bowl, and beat until smooth. Then, add 1 whole egg and 1 egg yolk, plus the vanilla and mix until combined.
In a separate bowl, whisk together the flour, salt, and baking soda. Slowly add the dry ingredients to the mixing bowl, beating just until the dry ingredients are incorporated.
Spread the dough into the pan evenly. Sprinkle chocolate chips and marshmallows across the top.
Bake 20-25 minutes until the edges are set. Watch that the marshmallows don’t get too brown, unless that’s how you prefer your s’mores!
