In a medium mixing bowl, stir the egg, peanut butter, banana and honey until smooth.
Add 1 cup of flour, wheat germ and oats to the peanut butter mixture and combine. The dough will be sticky.
Knead, adding more flour, on a well-floured surface until firm. Roll to ¼-inch thickness and cut into desired pieces.
Place cookies on a lightly greased or parchment-lined baking sheet and bake in a 300ºF oven for 25-30 minutes, based on the cookie size, until golden. Turn the oven off, open the oven door, and allow the cookies to cool.
