Crush graham crackers in a baggie using a rolling pin. You could also use a food processor if you have one! Add your melted butter, sugar, and salt.

Mix softened butter and brown sugar. Add eggs, water, and vanilla. Mix until incorporated.

Combine dry ingredients together, and add a little at a time to the wet ingredients.

Add chocolate chips, just until mixed. Add in graham cracker mixture, mixing with your fingers.

Roll dough into small balls and place on a greased cookie sheet. Bake at 350 degrees for around6 minutes.

While cookies are baking, cut marshmallows in half. After 6 minutes press in half of a marshmallow.

Return to the oven for 2 more minutes. Then remove and add a chocolate candy bar piece.
