Peanut Butter Yogurt Oatmeal Bars

I’ve got a buncha stuff to memorize, and a buncha yogurt in the house. Let’s bake!


Put on the Edie Sedgwick soundtrack…


…and measured out a lot of sugar.


This was a recipe I adapted from Adrienne’s Cookie Recipe. There’s no oil/butter in it, just greek yogurt, bananas…


…and lots of peanut butter!


Also in there – rolled oats and flour.


I didn’t use any mix-ins, and I also didn’t have the patience to roll the dough into little balls!


While the bars baked, I ate breakfast and memorized lines for Nice Girls Crew 2 – we just confirmed the time for our live chat on Thursday, November 1st, 7pm PT!


I can’t tell you how great these smelled as I photographed them…


…or how badly I wanted to crawl into bed and eat the entire pan with a fork…


…but instead I kept working, and allowed them to cool for a few hours, so they’d cut nicely into 15 squares.






Packaged up a dozen to share, and ate the last one standing…


…all the crumbs…



…and every last bit!



I’m pleased with how they turned out – but don’t bite in expecting a chewy gooey blondie, or something packed with Peanut Butter. They’re hearty, and very subtle in flavor – perfect for breakfast or a late afternoon snack.

Peanut Butter Yogurt Oatmeal Bars


  • 1/2 cup Nonfat Greek Yogurt (I used Stonyfield Oikos)
  • 3/4 cups Brown Sugar
  • 3/4 Cups Organic Sugar
  • 3 Eggs
  • 1 teaspoon Vanilla
  • 1 Banana, Mashed
  • 1 1/4 cup Natural Peanut Butter
  • 2 Teaspoons Baking Soda
  • 3.5 cups Rolled Oats
  • 1 cup All Purpose Flour


Combine the yogurt and sugars, then add vanilla/eggs/banana/peanut butter.

Mix the baking soda, oats, and flour. Add to the wet ingredients.

Pour into a 9×13 pan lined with parchment paper.

Bake at 325 degrees for 40-45 minutes, until a toothpick comes out clean. Allow to cool before cutting.

    They came out good! I should have mixed it more I think?

    I made a few changes…first I made a half batch. I used a whole banana tho. I added an apple, I subed 9 packets of stevia and 1 tablespoon of honey instead of the sugar. I don’t taste the walnut butter at all however when I tasted the dough I could…that’s why I think I didn’t mix it well. I’m assuming some will have the taste more than others. I could totalllllyyyy eat the whole pan!!! Total comfort food. I entered all the ingredients into fitness pal-250 calories and 12 grams of fat. I think ill skip the PB nxt time so the calories & fat will be less. Oh & I added cinnamon, a dash of nutmeg & and some extra vanilla. Thank u again so much!!!!
