Easy Oven Baked S’mores Bars

Oven Baked S’mores are one of my favorite desserts. Chocolate + Marshmallows + Graham Crackers = Deliciousness not matter which way you look at it. There are so many varieties of s’mores. You can make bite-size S’mores Dessert Cups, Waffle S’mores, S’mores Dip, or Peanut Butter S’mores Bars and those are just a few ideas.

Sure, s’mores are super popular in the summer but what about those s’mores cravings in the winter when there is no campfire nearby? That’s when it’s time to make Easy Oven-Baked S’mores Bars. These are so good that you may never just have regular old s’mores again.

What are S’mores?

A s’mores is traditionally a campfire snack or dessert with toasted marshmallows and a layer of chocolate placed between two pieces of graham cracker.

Who originally came up with this delicious treat though? Well, it’s not exactly clear but Wikipedia has some great theories.

S’more is a contraction of the phrase “some more”. S’mores appeared in a cookbook in the early 1920s, where it was called a “Graham Cracker Sandwich”. The text indicates that the treat was already popular with both Boy Scouts and Girl Scouts. In 1927, a recipe for “Some More” was published in Tramping and Trailing with the Girl Scouts.

The contracted term “s’mores” appears in conjunction with the recipe in a 1938 publication aimed at summer camps. A 1956 recipe uses the name “S’Mores”, and lists the ingredients as “a sandwich of two graham crackers, toasted marshmallow and ​12 chocolate bar”. A 1957 Betty Crocker cookbook contains a similar recipe under the name of “s’mores”.

Now, that you know all you need to know about traditional s’mores, it’s time to switch things up and make one of the most delicious s’mores treats that you’ll ever eat.
