Line a muffin tin with liners and set aside.
Place the chocolate and coconut oil into a microwave-safe bowl. Heat the chocolate on high for 20-second increments until the chocolate is melted. Be sure to stir the chocolate and coconut oil in between increments.
Scoop 1 tablespoon of the melted chocolate into each muffin liner. Holding the muffin tin at a slight angle, gently rotate so the melted chocolate coats the sides of each liner. It should go up the sides just above halfway.
Place the muffin tin in the freezer for 2 minutes. And set the remaining melted chocolate aside.
After 2 minutes, add ½ tablespoon of melted chocolate to the muffin liner and repeat, turning the muffin tin at an angle. Pop back in the freezer for 5 minutes.
While the chocolate shell is freezing, prepare the filling. Place all of the ingredients into a large mixing bowl and stir to combine. Set aside.
Once the shells have frozen, scoop 2 tablespoons of filling into each cup.
Top each cup with 1 tablespoon of the remaining melted chocolate. If the chocolate is not pourable, microwave in 10-second increments. The chocolate should be just loose enough to pour or drizzle over the top. Shake the pan so that the chocolate is completely covering the tops of the filling.
Place in the freezer and freeze for at least 30 minutes.
When the chocolate is frozen, enjoy immediately or store the protein cups in a freezer-safe bag.
