Skinny Pumpkin Oat Bars

I’m sneaking one more pumpkin recipe in before November is over.

I love to take recipes and tweak them so they have less calories, but still taste amazing.  Don’t get me wrong, the original recipe for these bars is insanely delicious but my version is too, with 1/3 the calories and half the sugar. An indulgence without the guilt.

One of my favorite things to use as a lower calorie substitute is powdered peanut butter. This can be used in place of traditional peanut butter in most recipes. Powdered peanut butter has the same delicious flavor as traditional peanut butter but contains 1/3 of the calories. It can also be used as a tasty addition to shakes, smoothies or yogurt. Below is my favorite brand from Costco.

I love pumpkin, since the beginning of October I have been making all sorts of different pumpkin treats. This is definitely one of my favorites. I made the original recipe and honestly, they were a little too sweet for my taste. This version is a must try!

Skinny Protein Pumpkin Oat Bars

Gluten free, packed with protein and ready in less than 20 minutes. 


  • 3 Cups Rolled Oats
  • 1 Cup Powdered peanut butter
  • 1/4 Cup Honey
  • 1/2 Cup Chocolate chips (I like the mini ones)
  • 1 Egg
  • 1/2 Cup Vanilla protein powder
  • 1/3 Cup Plain pureed pumpkin
  • 2 tsp Cinnamon
  • 2 tsp Baking Soda
  • 1/2 tsp Vanilla extract


  1. Preheat oven to 350 degrees. 

  2. Line a 9x13 pan with parchment paper or non-stick foil. I love the Reynolds Wrap non stick foil, no mess to clean up! 

  3. Put powdered peanut butter in a bowl, add protein powder. Slowly add water and mix until it becomes the consistency of regular peanut butter. 

  4. Add pumpkin, honey, vanilla extract, baking soda, cinnamon, and egg. Mix well. 

  5. Add oats and chocolate chips, mix well. 

  6. Use the back of a spoon to spread mixture evenly in pan. 

  7. Cook for 13-15 minutes. Do not overcook. I like them slightly undercooked so they are chewy. 

  8. Put in refrigerator for at least 2 hours before eating. This helps them become less sticky. 

  9. Cut into equal sized bars and enjoy!
