Peel and mash the banana in a high-speed blender, food processor, or mixing bowl until smooth.
Add the sifted coconut flour, salt, cinnamon, allulose, maple syrup, peanut butter, and 1/4 cup milk to the mashed banana.
Blend or mix until a uniform dough forms; if the mixture is too thick, add additional milk 1 teaspoon at a time, and if too thin, add a little more coconut flour.
Fold in the chocolate chips, if using, until evenly distributed.
Use your hands to form the mixture into 16 bite-sized balls.
Refrigerate the balls for at least 20 minutes to firm up before serving.
