I am sad to think that for years I didn’t eat S’mores.  When you aren’t a marshmallow fan it seems so logical.  Then I discovered the transformation of a roasted marshmallow and my mind was changed.

Here is the deal…the roasted marshmallow can’t be under cooked or over cooked.  There needs to be a nice hue of brown on the outside of the marshmallow which takes some time.

If you get too impatient then they usually catch on fire and it is ruined.  If you don’t cook it long enough then they taste like they are right out of the bag…so what is the point.

There is an art and commitment level to getting them just right.  Or you can make these cookie bars and guess what?  The oven gets the marshmallows just right for you!

How to Make S’mores Cookie Bars with a Graham Cookie Base

Combine butter and both sugars with a hand held mixer {or by hand}.  

Just like any other cookie, it is important to combine the butter with the sugars.  That way the sugar almost dissolves into the butter.

Next add the eggs, vanilla and graham cracker crumbs.  Combine until everything is nicely incorporated.

Press 2/3 of the mixture into the bottom of a 9×13 pan that has been sprayed with non-stick cooking spray.  Reserve the remaining 1/3 for the top.

Fudge Cookie Layer

The milk chocolate fudge cookie layer is taking the place of the chocolate bar in the S’more.  

To make it, combine the sweetened condensed milk, chocolate chips and butter into a microwave safe bowl.  Microwave for 2 minutes and stir. 

Continue by adding 30 second intervals and stirring until you have a smooth and creamy fudge mixture.

If you only have a few chocolate chips that haven’t melted then the heat from the milk will melt them.  So just stir and watch them melt before your eyes.

Look at this milk chocolate goodness!
