Preheat the oven to 350°F. In a cup or small bowl, mix ground chia seeds with 1/2 cup water and stir. Let sit for 2 minutes to form a gel.
In a Vitamix or other high-powered blender, combine chia seed gel, white beans, peanut butter, 1 banana, sweet potato, dates, cinnamon, nutmeg and vanilla extract. Blend until smooth and creamy.
In a large bowl, combine the whole-wheat flour and baking powder and mix thoroughly. Add the blended mixture to this dry mixture and mix until flour is totally combined. Stir in apricot slices and thin slices of banana and mix.
Place parchment paper on a large cookie sheet or coat sheet with a thin layer of cooking spray. Drop batter by spoonfuls onto the sheet and bake for 20 minutes.
