Peanut Butter and Chocolate Chip Breakfast Bars

breakfast bars - featured

Mornings are rough enough as a mom and wife, and the last thing I get a chance to do is have an actual wholesome breakfast. First things first, the hubby needs to have his lunch, his morning coffee and snacks, all his charged devices before he walks out of the door (he is our sugar daddy after all, we have to take care of him). As for Liam, well he owns the joint, so all focus is on him after that. Where does that leave mom? Starving and drinking a lonely cup of coffee. 

I tried the “coffee breakfast diet” and it didn’t work out. I like to work out after my sons first early morning nap and if I don’t eat anything, well – A. I’m freaking starving and B. I lose motivation in all my morning housework, play time and during my actual work out because again, I’m starving! I said to myself “Sharon, you got to eat”. Woah, motivational. That’s where I thought, breakfast bars! They are quick, delicious and packed with protein!


These breakfast bars work great for a quick breakfast or snacks. You can also, you guessed it, meal prep! These are so delicious, you would need to bake a batch every other day or everyday because they just won’t last! Trust me, you will be wanting to meal prep. 

Now if you are only making a week of prep at a time, you simply place them in an airtight container. If you plan on prepping for past 1 week and up to 3 months, I recommend wrapping them individually with clear wrap and freezing them in a ziplock bag.  Wrapping them individually allow you to defrost only the amount you want and not the entire batch. Let them come to room temperature and slightly warm them in the toaster oven to soften that chocolatey gooeyness. Uh yum!


Now when I mean these bars are simple, they really are simple. Im talking one bowl recipe type of simple. The ingredients are also common pantry staples, minus the protein powder. You can even omit the protein powder if that isn’t a part of your life style, simply add an extra 1/4 cup of oat flour to your mixture. If you do wish to incorporate protein powder you can purchase a big tub at your local grocery outlets, such as Costco and Target. You can also visit your local health and vitamin store, Max Muscle or GNC (as examples), if you wish to gather more in-depth information on which protein powder is right for you. We are Max Muscle shoppers and we buy the Chocolate Cake Max Pro Elite from MaxMuscl(courtesy of my husband). 

Now a quick little list of ingredients needed…

  • oat flour (grind old fashioned oats in the blender)
  • protein powder of choice (we use chocolate)
  • milk
  • brown sugar
  • white sugar
  • creamy peanut butter
  • vanilla extract
  • dark chocolate chips (can also use sweet or semi-sweet)
  • sea salt
  • baking powder
  • walnuts (optional)

Bake at 350F in an even layer within a 8×8 baking dish lined with parchment paper. The sides should be golden and the top lightly browned, about 16-20 minutes. You do not want to over cook these bars or they will begin to crumble and fall apart when you cut them up. If possible, slightly undercook them, you want your tooth pick or fork to be 95% clean. 

Once done, remove from the oven and allow them too cool in the pan for 10 minutes (this will let them finish off any cooking necessary). Remove from the dish by the edges of the parchment and fully cool before cutting up into delicious squares!

  • 1 cup Peanut Butter (creamy)
  • ¼ cup White Sugar
  • ¼ cup Brown Sugar (light)
  • 1/2 tsp Vanilla Extract
  • 1 1/4 cup Oat Flour*
  • ¼ cup Protein Powder** (Chocolate)
  • 1.5 tsp Baking Powder
  • ¼ tsp Sea Salt
  • 1/3 cup + 1 tbsp Milk (whole, 2%, fat free, or lactose free)
  • ½ cup Chocolate Chips, Dark
  • ¼ cup Walnuts (pieces)


  • Preheat the oven to 350F.
    Line a 8x8 baking dish with parchment paper.
  • Mix the peanut butter, white sugar, brown sugar and vanilla extract for 1 minute until the ingredients are well distributed.
  • Add in the oat flour, protein powder, baking powder and sea salt, and mix until evenly combined. The mixture will still be dry and crumbly.
  • Add the milk and mix to bring the mixture together. The milk will get the mixture wet enough to stick together.
  • Fold in the chocolate chips.
  • Place the wet oat mix into the prepared baking pan; evenly flatten out over the entire bottom of the dish.
  • Sprinkle the walnuts over the top and slightly push down into the mix.
  • Bake until the edges begin to golden and the top is slightly golden, about 16-20 minutes. Do not over bake or the bars will become too crumbly and break apart when it comes time to cut them. Stick a toothpick in the center and you want it to be 95% clean.
  • Allow the bars to cool for 10 minutes in the pan (this will allow the bars to finish cooking without drying out).
  • After 10 minutes, grab the edges of the parchment paper and remove from the pan. Allow to fully cool before cutting into your desired size squares. I cut 12 generous size squares. Enjoy!


  • * Oat Flour - to make oat flour - grind oat fashioned oats in the blender until it resembles a fine flour like powder
