Stir in powdered sugar and vanilla. As you can see, the mixture will be pretty thick, so put it in the microwave and zap it for about 45 second until it becomes more spreadable.
Spread the other 1/2 of the white chocolate over the top and swirl if you’d like.
Sprinkle with chopped graham crackers.
Drizzle with melted candy discs. Place the pan in the fridge for about 10 minutes to set.
Cut into pieces and partake or wrap and give to someone else to enjoy.
