Place a piece of parchment paper on a baking sheet. Set aside.
Break each Hershey's Milk Chocolate Bar apart and chop each pip in half. If you don't want to use a knife, just snap them in half with your fingers!
Place Honey Maid Graham Cracker Squares in a small plastic bag and crush them into small chunks.
For the marshmallows, you have two options: You can leave them whole, or cut each Kraft's Jet Puffed S'moreMallow into four pieces. Or a mix of both for kicks! Place marshmallows on prepared baking sheet and set aside.
Place ½ of your crushed graham crackers in the mason jar. Set aside.
Set oven to broil and place sheet of marshmallows in the oven long enough to toast the marshmallows on top to a light golden color. It won't take very long, so keep an eye on it!
Carefully scoop (or place) ½ your marshmallows on top of the graham cracker layer in the jar.
Add ½ of your chopped chocolate on top of marshmallow layer, and repeat the sequence again (all but a pinch of the remaining graham crackers, marshmallow, and then chocolate).
Sprinkle the remaining graham crackers on top and serve immediately. Enjoy!Tip: Want it to be extra ooey-gooey? Pop the assembled jar into the microwave for 10-15 seconds before serving.
