Prepare a cookie sheet by lining it with wax paper or parchment paper OR set out 24 mini cupcake liners. Finely crush the additional 2 tablespoons of graham cereal and set aside.
Place the chocolate in a medium glass or pyrex bowl that is microwave safe. The bowl should be large enough to mix in the marshmallows and cereal (do not add those ingredients yet).
Melt the chocolate in the microwave. Melt for 30 seconds, then stir thoroughly. Then continue melting in 15 second intervals, stirring thoroughly after each time in the microwave. It shouldn't take more than 45-60 seconds total to melt the chocolate.
Immediately stir in the marshmallows and graham cereal, stirring thoroughly until everything is coated.
Scoop out candy by rounded tablespoons and drop onto the prepared cookie sheet or into each mini cupcake liner. It's easiest to do this with a cookie dough scoop. Work quickly so you can scoop them all before the chocolate begins to set. Sprinkle some of the crushed cereal on top of each candy.
Place the candies in the fridge for 30 minutes to set up, then remove from the refrigerator and store at room temperature. You can leave them to set at room temperature but it will take much longer for them to completely set, especially is your house is warm.
When candies are completely set, store in an airtight container.
