Add marshmallows and butter to a large saucepan and heat until melted. Stir in the orange food coloring and vanilla extract.
Pour marshmallow mixture into a large mixing bowl with the cereal and mix until well incorporated.
Divide the mixture evenly among two disposable pie pans. Allow to chill until set (1-2 hours). Cut each of the pans of rice krispie treats into 8 even slices.
Heat the white chocolate in a microwave-safe bowl for 1 minute, stir, then heat in 15 second intervals until melted. Stir in coconut oil until smooth. Repeat this process for the milk chocolate.
Dip the tips of each triangle rice krispie in melted white chocolate and set for 10 min on parchment paper. Dip the opposite ends of the treats into the milk chocolate.
Allow to dry completely.
