|Preheat oven to 375 degrees. Line baking pans with parchment paper. Lay graham crackers side by side on pans as close as possible.|
In a medium bowl, sift together flour, baking soda, salt and cinnamon.
In a large bowl, cream butter with sugars until light and fluffy. Add eggs, one at a time, and vanilla; mix until combined.
Add flour mixture to the butter mixture and combine.
Fold in the chocolate chips and marshmallows.
Place 1 1/2 tablespoons of dough on each graham cracker square, pressing lightly. Bake for 5 minutes.
Remove from oven and press a chocolate rectangle on top of each. Bake for 5-7 more minutes or until dough is golden brown at edges.
Remove to wire rack to cool. Cool completely before cutting with a sharp knife.
