  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.

This is the first recipe I've used to make my own protein bars. I used 1 package (35g) of vanilla and 1 package of chocolate protein by Vega Sport, Naturally More Peanut Butter which is great as it already contains flax seed, honey and egg white, added some chopped walnuts, dried cranberries and other fruit and nuts from trailmix. I also added a bit more honey and heated it a bit with peanut butter to make it more liquid and easier to mix with dry ingredients. The bars turned out great (chewy!), I can't wait to take them on my next hike!

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 around with the flavors a bit as I still found them on the bland side even after adding all that honey...

Very easy recipe and these protein bars turned out very good. I added 1T of vanilla and 1T of cocoa powder also to bump up some flavour since my protein powder is flavourless. Mine didn't turn out crumbly but they are crunchy. I may add some applesauce next time and see if I get a chewier bar. Overall, very good recipe for protein bars.

I made this recipe as written and doubled the honey as suggested by the author for a sweeter bar. They turned out great... moist, not too crumbly, and very tasty!

Loved these bars and I make them every two weeks now. I work out a lot and hate eating food I have to unwrap, so these are perfect. I add 1/3 cup of wheat germ, 1/3 cup of ground flax seed, ram it full of chopped almonds, two eggs, vanilla and double the honey. I add apples sauce if I have it but not required, these taste great. Once cut up, I freeze the entire batch in a large freezer bag and pick one out a day, they don't last long in the house because the kids love them also. Thanks for the recipe!!

Just made these and they are very good. I added 2 tblspn Cinnamon and instead of flax seed, I grounded some almonds, soy nuts, pumpkin kernels and dried cranberries from a trail mix. Next time I will ground the oatmeal as well to try a different texture. Thanks for the recipe

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 too.) The kids (Ages 12, 10 and 7) Loved them and asked for seconds. They thought it would be really good in milk too. You can really taste the peanut butter, honey and the bananas too. YUM!
