Gently snap one of the whole graham crackers into 4 pieces (snap at the perforated line).
Using a zipped plastic bag place the other two graham crackers into it and zip closed. Then roughly crush (you don’t want them too fine) the graham crackers with your hands or use a rolling pin. Place the crushed graham crackers on a small plate. Set aside.
Break the chocolate bar into small pieces and place in a microwave safe bowl. Microwave the chocolate in 25 second increments, stirring in between until melted.
Dip the rim of the root beer mug into the melted chocolate. Gently roll the rim into the crushed graham crackers so that the rim is coated completely. Using an iced tea spoon, drip some of the melted chocolate down the inside of the mug and allow it to run down. Repeat this process with the second mug. Place both of the mugs in the fridge so that the chocolate will set up and harden. This will take about 10 minutes.
Dip about 1/4 of each marshmallow into the melted chocolate and place on a small plate. Dip about 1/4 of each graham cracker into the melted chocolate and place on a small plate with wax paper. Place both plates in the fridge to allow the chocolate to set up and harden. This will take about 10 minutes.
Once the chocolate has set, thread three marshmallows onto a skewer. Repeat with remaining three marshmallows and skewer. Set aside.
Cut two tiny slices of the chocolate pie. Set aside.
Put the ice cream and milk in a blender and blend until combined. You will want to stop a couple of times to stir so the ice cream and milk will get mixed in well.
Pour the milkshake evenly into the two refrigerated root beer mugs.
Top the milkshake with a good amount of whipped cream (you want it a couple of inches above the top of the mug). Add a marshmallow skewer to each mug. Gently push two of the chocolate covered graham crackers into the whipped cream of each mug. Top each with a tiny slice of pie. Add a cute straw. Enjoy!
We highly recommend to place each mug on a small plate incase you have any overflow as you enjoy. 🙂
