Break graham crackers in half and set aside.
Place 1 cup milk chocolate chips and 1 cup semi-sweet chocolate chips with 1 teaspoon of coconut oil in a microwave-safe bowl and melt for one minute. Stir and microwave in 30 second increments, stirring in between until the chocolate is melted.
Dip the cracker halves into the chocolate, and gently tap to remove any access chocolate. Then lay the crackers onto a baking sheet lined with parchment paper.
Place the baking sheet in the fridge for 10 minutes or until the chocolate has hardened.
Add peanut butter, powdered sugar and vanilla into a mixing bowl and stir until all combined.
Use a medium cookie scoop to add a 2" ball of peanut butter mixture on top of each cracker.
Spread the peanut butter mixture evenly over the crackers to the edges. Place in the refrigerator for at least 5-10 minutes.
Melt the other 2 cups of chocolate chips with coconut oil in the microwave.
Dip the peanut butter chocolate-covered crackers into the melted chocolate and gently lift out with a fork. Let the excess chocolate drip off and set it back down on the lined baking sheet. Place the peanut butter squares into the fridge for the chocolate to set for at least 10 minutes.
Melt some orange, green and purple melting wafers (separately) in the microwave according to package directions. Pour into a small baggie and cut off the corner. Drizzle some of each color over the top of the peanut butter squares for a fun Halloween look.
