Peel a ripe banana and place it in a bowl. Use a fork or a potato masher to mash the banana until it reaches a smooth consistency.
To the mashed banana, add agave nectar (honey or maple syrup works as a sub), melted coconut oil, and natural peanut butter.
Use a spoon or a whisk to thoroughly mix all the ingredients together until well combined.
Prepare a bread pan by lining it with parchment paper. You can use clothespins or chip clips to secure the parchment paper in place. Transfer the banana mixture to the prepared bread pan, spreading it evenly with a spatula or the back of a spoon. Place the bread pan on a flat surface in the freezer to set for about 10-15 minutes, or until it firms up slightly.
Make the Chocolate Layer
In a medium bowl, combine the peanut butter, melted coconut oil, agave nectar (honey or maple syrup as a substitution), and unsweetened cocoa powder. Whisk the ingredients together until they are well combined. Once the peanut butter, coconut oil, agave, and cocoa powder are fully combined, gently fold in the crispy puffed quinoa.
After the banana layer has chilled in the freezer for about 10-15 minutes and has firmed up slightly, take the bread pan out of the freezer and pour the chocolate mixture on top of the chilled banana layer. Use a spatula or the back of a spoon to spread the chocolate layer evenly over the banana layer, making sure it reaches the edges and corners of the pan.
Once the chocolate layer is evenly spread over the banana layer, place the bread pan back in the freezer to chill for at least 1 hour, but preferably overnight. This will allow the chocolate layer to fully set.
Cut & Enjoy!
Once the banana bites have fully set in the freezer, pull on the edges of the parchment paper to carefully lift the entire block of banana bites out of the pan in one piece.
After removing the frozen banana bites from the pan, let them sit on the counter for a few minutes to slightly soften before cutting into them. Cut into 18 small squares and sprinkle with flakey salt (if desired).
