What is a S’mores Cookie Bar?

According to Food & Wine, the first s’mores recipe was part of a Girl Scout Handbook. Originally called “some more” but it’s unclear how it shortened to just s’more. Whatever we call it – it remains the best end-of-summer-treat that I can think of.

Instead of the usual cookie baked individually – the cookie dough is baked in a baking pan. Once cooled, the cookie is cut into squares which results in a cookie bar! Most importantly, cookie bars are thick and chewy!

Tools needed

• 1 large mixing bowl
• Measuring cups and measuring spoons
• Parchment paper
• 9inch x 9inch baking pan
• Whisk or Hand mixer
• Spatula

S’mores Cookie Bar Ingredient Breakdown

• Graham crackers: This is the first of 3 main ingredients in s’mores. The whole graham cracker at the bottom gives the cookie bar a foundation and gives a good crunch – like a real s’more!
• Flour, Baking soda, salt: Basic dry ingredients for any cookie. Mixing these 3 dry ingredients together will distribute the baking soda with the flour. The result will be an evenly baked cookie bar!
• Melted butter: Using melted butter helps the cookie bar have an even colour and bake.
• Sugars: Both white granulated and dark brown sugar will tenderize (soften) the s’mores cookie bar.
• Vanilla extract: Artificial vanilla extract is used for essential flavouring.
• Eggs: Holds the cookie bar together, which helps with cutting into squares.
• Marshmallows: The 2nd main ingredient in s’mores. Instead of the giant marshmallow for campfire s’mores, using Mini marshmallows ensures each bite has a chewy marshmallow to enjoy.
• Milk chocolate chip: The last s’mores ingredient. Using milk chocolate gives the s’mores cookie bar the sweetness and milkiness that we enjoy when roasting s’mores.
• Semi-sweet chocolate chip: In addition to milk chocolate chips, semi-sweet (or dark) chocolate chips adds a yummy chocolatey taste.

Notes

Storage: Once completely cool, store in an airtight container for up to 5 days. Warm up slightly in the oven or microwave to recreate the melty and ooey-gooey campfire s’more.

Baker’s Tip: The S’mores Cookie Bar will look underbaked but if cooled completely in the pan, it will be the perfect texture.
