In a microwave safe bowl, combine one cup of the dark chocolate chips and 1 tablespoon coconut oil. Heat the chocolate chips in the microwave, on 50% power, in increments of 45 seconds, stirring after each increment, until the chocolate is fully melted.
Meanwhile, add the creamy peanut butter (see note if using a thick peanut butter like Jiff), date/maple syrup, vanilla, and 1 tablespoon coconut flour together in a bowl and stir until it forms a thick paste that you can easily form into a ball. If it's too runny, add another tablespoon of coconut flour.
Melt remaining melted dark chocolate chips and coconut oil in a microwave safe bowl (again on 50% power, in increments of 45 seconds).
Divide the remaining dark chocolate between the muffin liners so the peanut butter mixture is fully covered.
If you are using a less runny peanut butter (like Jiff Naturals) or your peanut butter has dried up a bit, you should microwave it for 30-45 seconds to help loosen it up so its easier to combine all the ingredients to make the peanut butter layer.
