First, melt the cannabis butter in a saucepan over low heat.
Stir in the miniature marshmellows until they are melted and well combined. Cook for an additional two minutes, stirring continuously.
Add the Rice Krispy cereal into the saucepan. Stir until the cereal is well-coated in the cannabis/ marshmallow mixture.
Using a buttered spatula, press the mixture firmly and evenly into a 9 x 13-inch pan.
Allow the mixture to cool for 10 minutes. Once cooled, cut the Rice Krispy edibles into even squares (this helps ensure the potency stays consistent). Enjoy!
