Place the pitted Medjool dates in a food processor and pulse until they form a thick, sticky paste.
Add the oat flour, chocolate protein powder, cocoa powder, almond butter, maple syrup, and fine sea salt to the food processor.
Process the mixture until a cohesive dough forms that pulls away from the sides of the bowl.
Divide the dough into 12 equal portions and roll each into a smooth sphere using your palms.
Place the protein balls on a parchment-lined tray and freeze for 10 minutes to firm up.
Combine the dark chocolate chips and coconut oil in a small microwave-safe bowl.
Microwave the chocolate in 30-second intervals, stirring between each, until completely melted and glossy.
Using a fork, dip each chilled ball into the melted chocolate, letting the excess drip off before returning it to the parchment paper.
Immediately sprinkle the top of each ball with flaky sea salt while the chocolate is still wet.
Refrigerate the balls for 20 minutes to allow the chocolate shell to fully set before serving.
