Line a baking sheet with parchment paper. You can use a 9x9 baking dish, 9x13 baking dish or a 13x18 baking sheet, depending on how thick you want your bark.
In a medium bowl, mash one banana. Add in the yogurt and honey (if using) and stir until combined.
Pour the yogurt mixture onto the baking sheet and spread with a knife or spatula until you have a smooth layer.
Swirl on the peanut butter and sprinkle on the mini chocolate chips. If your peanut butter is too thick, you can place it in a small bowl and heat in the microwave in 20-second increments. Slice the remaining banana and place it on top of the yogurt.
Place the baking sheet in the freezer for at least 5 hours. Take the baking sheet out of the fridge and break the yogurt bark into chunks with your hands.
Serve and enjoy.
