Start by peeling the ripe bananas and slicing them into rounds approximately ½ inch thick. Arrange the slices on a plate and set aside.
In a microwave-safe bowl, combine the dark chocolate chips and coconut oil. Heat in the microwave in 30-second bursts, stirring thoroughly after each interval, until the chocolate is completely melted and achieves a smooth consistency.
Prepare a baking sheet by lining it with parchment paper. This will help prevent the banana bites from sticking and make for easy cleanup.
Take each banana slice and dip it into the melted chocolate, making sure to fully coat the slice. Gently shake off any excess chocolate before placing it onto the prepared baking sheet.
While the chocolate is still wet, sprinkle the coated banana bites with a pinch of sea salt, and add any optional toppings like crushed nuts, shredded coconut, or fun sprinkles to add flavor and color.
Once all the banana slices are coated and decorated, transfer the baking sheet to the freezer and let them chill for about 30 minutes, or until the chocolate has fully hardened.
After chilling, you can enjoy your delicious chocolate-covered banana bites immediately, or store them in an airtight container in the freezer for freshness for up to a week.
Notes
Consider serving the banana bites on a decorative platter with a drizzle of any remaining melted chocolate for an elegant touch.
