Line a muffin pan with 12 silicone muffin liners or grease with coconut oil.
Add the peanut butter, coconut cream, and coconut oil to a glass bowl. Gently melt the mixture over a double boiler while stiring occasionally, or melt the mixture in the microwave by microwaving for 30 second intervals and stirring in between intervals until fully melted.
Once melted, remove the bowl from the microwave or double boiler and add the maple syrup and vanilla. Stir until combined. Add the puffed rice and stir until combined.
Spoon the mixture evenly into the prepared 12 silicone muffin liners or greased muffin cups. Press the mixture down firmly. Place in the freezer while you prepare the chocolate coating.
To prepare the chocolate coating, melt 2 tablespoons of dark chocolate OR prepare the chocolate coating mixture by adding the cocoa or cacao powder, melted coconut oil, and maple syrup to a small bowl. Stir until fully combined.
Remove the rice krispie cups from the freezer and drizzle the melted chocolate or chocolate coating over each rice krispie cup.
Place in the freezer to set for at least 2 hours.
Pop the rice krispie cups out of their silicone moulds or pan. You can enjoy these straight from the freezer or let them thaw slightly before enjoying them. Store the rice krispie cups in the freezer.
