Break the graham crackers into squares.
Spread strawberry frosting on one graham cracker square and top with another square to make a sandwich.
Melt the chocolate candy melts in the microwave in 30-second increments, stirring between each interval until smooth.
Dip each graham cracker sandwich into the melted chocolate until coated.
Place the coated sandwiches on a silicone baking mat or parchment paper and allow the chocolate to set completely.
Melt the pink candy melts in the microwave in 30-second increments, stirring until smooth.
Drizzle the melted pink candy melts over the chocolate-covered graham cracker sandwiches.
Immediately decorate with Valentine sprinkles and allow the candy coating to set before serving.
