Prepare an 8×8 inch square pan with parchment paper

In a large saucepan, melt the butter completely

Once the butter is melted, add in 6 cups of mini marshmallows and stir until completely melted

Remove the saucepan from the heat and add in the peppermint extract and stir in the Rice Krispie cereal; mix until fully combined 

Pour the mixture the prepared pan and allow it to cool completely before cutting

Once they are ready to cut, remove the Rice Krispie Treats from the pan and cut into three equal strips and then cut each strip into triangle pieces  

Place the triangles onto a baking sheet while you melt the white chocolate

In a medium microwave safe bowl, melt the white chocolate chips and the coconut oil in the microwave for 30 second increments until the chocolate is melted and smooth

Dip the top of each triangle rice krispie treat into the white chocolate and place back on the baking sheet to allow the chocolate to dry

Once the chocolate is dry, drizzle the top of each with the remaining white chocolate and sprinkle the lines with crushed peppermint

Serve or store in an air tight container
