You more than likely already have these ingredients in your pantry, too. Especially if you bake quite a lot. It won’t take much to whip these up for an afternoon snack. You’ll love how easy they are. 

Three reasons why you need to make this recipe! 

They are low calorie and super healthy. 

Just two tablespoons of peanut butter have 16 grams of fat and 200 calories. One of these bars gives you the yummy peanut butter taste with only 7 grams of fat and under 150 calories. It’s a win win! 

Peanut Butter Oatmeal Bars make a fantastic after school snack. 

School is starting back soon, and your kids are going to want a snack when they come home. Skip the high sugar cookies or highly processed chips, and have these bars ready for them instead. You’ll feel good about the snack that you are giving them! 

Crumble bars are such a good tea time snack. 

Whether you’re a tea fan or a coffee fan, these peanut butter oatmeal bars go perfectly with a hot cuppa tea/coffee! Use these as a healthy mid-morning pick up me to get through until lunch. 

Ingredients you need to make Peanut Butter Oatmeal Bars: 

  • 1/2 cup unsweetened apple sauce
  • 1/4 cup brown sugar
  • 1 egg
  • 1 tsp vanilla
  • 1/3 cup peanut butter
  • 3/4 cup flour
  • 1 cup oats *I used quick oats
  • 1 tsp baking powder
  • 1/2 tsp baking soda

FOR THE CRUMBLE TOPPING

  • 1/4 cup flour
  • 1/4 cup brown sugar
  • 2 Tbsp peanut butter
  • 1 Tbsp light butter (softened)

How to make Peanut Butter Oatmeal Bars (step by step): 

  1. Preheat the oven to 350F and spray a 9 inch square dish with some nonstick cooking spray.
  2. In a bowl using an electric mixer, mix together the apple sauce and 1/4 cup of brown sugar. Add in the egg and mix well, then add in the peanut butter and vanilla and mix until well blended.
  3. Fold in the flour, oats, baking powder, and baking soda.
  4. Pour the batter into the baking dish and spread it out evenly.
  5. In a small bowl, mix together the crumble ingredients -flour, brown sugar, peanut butter, and butter. I find using a few knives and cutting it (like you would cold butter into flour) works well to form the crumble texture you want. A fork would also work. 
  6. Sprinkle the crumble on top of the batter then bake in the oven for 30 minutes.
  7. Let the bars cool then cut into 12 equal peanut butter oatmeal bars.

Different ways to change up this recipe: 

  • To make them nut free: use sunflower seed butter instead of peanut butter. It’s just as delicious and school friendly! 
  • Using PB2 Powder makes these 4 points each. You will use 2 tbsp of powder for the crumble topping, and 6 tbsp of powder for the actual recipe. Just mix with water to make the right consistency to add to the batter. 
  • Add a handful of Lily’s No Sugar Added Dark Chocolate Chips for a peanut butter oatmeal chocolate chip bar. 
  • It’s very easy to make these peanut butter oatmeal bars gluten-free! Just use a gluten-free flour blend in place of the all purpose flour. Almond flour will raise the weight watcher points, so a gluten-free blend is the way to go. 
  • Any nut butter will work in this recipe. You can use almond, cashew, or a blended nut butter in place of peanut butter. They all bake the same way, so it’s up to your personal taste preference. 
  • You can use pumpkin puree or mashed banana in place of the applesauce if needed. It will slightly alter the flavor, but not in a bad way. Bananas go great with peanut butter and oats! 

Tips and Tricks for Making Peanut Butter Oatmeal Bars: 

  • Optional: melt some peanut butter and drizzle it over the baked bars. I highly recommend this and you can do it over the whole thing or just per bar when you are ready to eat one. 
  • PB2 drizzle is a great option for the bars since you can make it as watery as you need for the drizzle. 
  • These bars freeze well- just make sure to keep them tightly wrapped and in a freezer zip lock bag. To thaw, let one sit on the counter at room temp for a few hours. 
  • Keep these bars in a tightly sealed container on the counter for up to 5 days. You can also store them in the fridge.

  1. Hi! I’m pretty new to Weight Watchers and this is one of the first recipes I found! It looks so delicious!!

    Did you use normal brown sugar or the Splenda brown sugar mix?

    1. Hi Autumn, welcome to WW πŸ™‚ I used regular but you could substitute for the splenda and adjust the points accordingly, I hope you enjoy the bars

  2. 4 stars
    Curious, could i add some chopped up apples to this? I feel like it would be a lot better with some kind of fruit. Thoughts?

  3. Do you think I could make these as muffins instead? I always find it so much easier to portion out that way.

  4. I made these last night and they are so yummy! Thanks again for a great recipe! By the way using Splenda brown sugar and regular brown sugar really is no difference. Really makes me angry LOL.

    1. HI Megan, hmmm not too sure, all I can say is give it a try and see, I think it will be ok just not sure if the crumble will be the same texture

  5. 3 stars
    I’ve made these twice. I followed the recipe to a t, apart from throwing in some Lily’s. Both times they came out really, really dry. I like the sound of them better than the result, sadly.
