Pre-heat your oven to 350 degrees. In a small bowl combine the orange juice and chia seed. Stir it every few minutes. The mixture should thicken after about 10 minutes.
In a small bowl combine the oats, baking powder, sea salt, wheat germ, cranberries, almonds and flour. In a large bowl whisk the eggs in with the smashed banana. Once the OJ-chia mixture thickens combine it with the egg and banana (add the sweetener here if you want). Stir in the dry ingredients until all is combined.
Line a baking sheet with parchment paper. Using a 1/4 cup or 1/2 cup measuring cup to scoop the mixture, form them into bars on the lined baking sheet. Depending on the size you want a 1/4 cup should make 10 bars and a 1/2 cup should make 5.
Bake for 15-18 minutes depending on the size of your bar. Move to a wire rack once done to cool.
