Melt your chocolate and coconut oil together in 30 second intervals until smooth, stirring in between each interval
Whisk remaining wet ingredients in the same bowl - eggs, coconut sugar, vanilla extract
In a separate bowl whisk dry ingredients - cocoa, tapioca, sea salt
Pour into greased 8 or 9" cast iron skillet
Bake at 350 for 20-23 minutes

Make ganache for melting dark chocolate over sauce pan (or microwave) over low heat, stirring regularly. Once it's mostly melted stir in coconut cream (or peanut butter if using instead)

Optionally, top with dye-free chocolate gems and chocolate ice cream (I used my homemade peanut butter cup chocolate ice cream in the ninja creami)
