2-3/4 cups flour
1 tsp. cinnamon
3/4 tsp. salt
1 tsp. baking soda
3/4 cup (1-1/2 cubes) real butter
1 cup packed brown sugar
1/2 cup sugar
2 eggs
1 tsp. vanilla
3/4 cup semi-sweet chocolate chips
1 packed cup mini marshmallows
32-36 graham cracker squares
1 package/roll of Rolos, halved
Cream butter, brown sugar and sugar in stand mixer about 3 min until fluffy. Add eggs and vanilla and mix until smooth. Add dry ingredients. Fold in the chocolate chips and marshmallows.
Using a medium scoop (about 1-1/2 Tbl.), scoop dough into balls and place them close together on parchment to freeze at least one hour or overnight.
Preheat oven to 390-400 degrees. Put 12 squares of graham crackers out on parchment-lined cookie sheet. Place a frozen ball of dough on each square. Bake until cookies are golden. Remove from oven and immediately press a half-Rolo into the crispy top of each cookie.
