Line a cookie sheet with parchment paper and set aside.
In a medium shallow microwave-safe bowl, melt the milk and dark chocolate together in 20-second increments.
Stir in between until smooth and no streaks appear. If chocolate won't become smooth add a teaspoon or two of coconut or vegetable oil to your chocolate.
Using a fork dip a graham cracker into the bowl of chocolate until it is covered and allow the excess to drip back into the bowl.
Place the dipped cracker onto a parchment paper lined cookie sheet. Continue this process with the remaining crackers. If desired use a fork to create texture in the chocolate.
Reserve 1 tablespoon of chocolate for drizzling.
Melt the white chocolate in a small microwave-safe bowl, in 20 second increments.
Place the melted white chocolate into a piping bag and drizzle over some of the graham crackers if desired. Do the same with the reserved milk and dark chocolate mix.
Garnish any remaining crackers with sprinkles.
Transfer the cookie sheet to the freezer for 10 minutes or the refrigerator for 30 minutes to set.
After the crackers have set enjoy with your beverage of choice!
