  1. Preheat oven to 350 degrees F (175 degrees C). Line a baking sheet with parchment.
  2. Spread oats out onto an unlined baking sheet in a thin layer, and toast until lightly browned, about 10 minutes; remove and allow to cool. Mix together the cooled oats, protein powder, whole wheat flour, and flax seed until thoroughly combined, and mix with peanut butter and honey. Mash the bananas into the mixture, and stir to combine. Press the dough down onto the parchment-lined baking sheet in a 1/2-inch layer.
  3. Bake in the preheated oven until the edges of the dough are golden brown, about 15 minutes; cut into bars while warm, and allow the bars to cool. Wrap bars in plastic wrap, and refrigerate until ready to use.


  • Cook's Note
  • These protein bars are not meant to be very sweet. If you would like to make them sweeter, double the amount of honey.

My picky teenage boys even liked these. They were a little dry so next time I will probably add some apple sauce to the mix. I added a dash of cinnamon and nutmeg. Good stuff, thanks!

Made these with my daughter today...The kids loved them but they were very crumbly. I will add more honey next time. (I wasn't watching when she put in the oats so she may have added too much to...

the batter was really crumbly so I had to add about 1/2 cup more honey and some applesauce to it. I also added some cinnamon for taste. I think these bars have some potential... i'm gonna play a...

My family really liked these. They're not sweet, but thats obviously not the intent of this healthy snack. If you prefer a sweet bar, I'd suggest adding some raisins or dried fruit; cheeries, o...
