Easy Peanut Butter Oatmeal Bars

What can we say? We’re a family who loves oatmeal bars [1]! These Peanut Butter Oatmeal Bars are no exception! Not too sweet, but totally satisfying! They make a nutritious, easy breakfast, snack or post-workout pick me up any day!

It’s hard finding healthy food recipes [2] the kid’s love, especially snacks that don’t come in a package or wrapper and contain icky processed ingredients.

Are Oat Bars Healthy?

One of our go-to healthy snack ingredients is oatmeal. Oatmeal contains calcium, potassium, and soluble fiber, so it’s good for your heart and health!

Plus, it’s so satisfying.

Oatmeal bars contain whole-grain ingredients and have the added benefit of a little protein when you add creamy peanut butter. This keeps the kiddos satisfied at snack time. (Natural peanut butter, of course 🙂 )

If you like bananas, you have to try these Banana Oatmeal Bars [3]!! If you want fruit in your bars, try our Raspberry Oatmeal Bars [4]. Addictive!

The more we read, the more we find it important to bake my own snacks and treats for my family. Artificial ingredients and preservatives are everywhere, so it’s important to balance that out with some wholesome goodness.

Easy Peanut Butter Oatmeal Bars are a delicious recipe idea your whole family will love! A healthy grab and go breakfast or after school snack!

One large bowl. One pan. One delicious snack!

Step 1

First, line your baking pan with parchment paper. (This will keep your bars from sticking and make them easy to take out.)

Now, combine all your wet ingredients – peanut butter, eggs, vanilla, and honey. Stir well. 

Step 2

Then add your dry ingredients (oats, baking soda, flour). Mix thoroughly and then press into a baking pan. 

Step 3

Place the pan in your preheated oven and bake for 15-17 minutes until golden brown. Then, let them cool and top with a drizzle of chocolate if you’re so inclined. (how could you not be inclined, it’s chocolate!)

Just melt your chocolate morsels in the microwave and drizzle over the bars.

  • mixing bowl
  • 8x8 baking pan
  • Spatula
  • parchment paper


  • 1 cup creamy peanut butter
  • 2 eggs
  • 1/2 cup honey or brown sugar
  • 2 tsp vanilla
  • 1 tsp baking soda
  • 1 1/2 cups old fashioned oats
  • 1/2 cup whole wheat flour
  • 1/4 cup dark or semi-sweet chocolate morsels


  • Preheat your oven to 350°F. Line the bottom of an 8x8 pan with parchment paper spray or with cooking spray.
  • In a medium mixing bowl add the peanut butter, eggs, honey, and vanilla. Mix to combine. Stir in baking soda, old fashioned oats, and whole wheat flour until everything is evenly incorporated.
  • Place batter in the prepared pan and press mixture into the bottom of the pan in an even layer. Bake for 15-17 minutes. If you overcook it, it may get dry. Stick a toothpick into the center, when it comes out clean it's done.
  • You can stop here or add a little chocolate topping. While bars cool on a wire rack, melt chocolate in the microwave in 30-second intervals, stirring between intervals until completely melted.
  • Once your chocolate is melted, drizzle over the top of the bars. Enjoy!



You can substitute regular flour for the whole wheat if you prefer.  
The chocolate drizzle is optional, but it makes the bars extra tasty.
