How to Make Oatmeal Breakfast Bars

This soft-baked oatmeal breakfast bar recipe combines the three musketeers of breakfast flavors: peanut butter, banana, and oatmeal. It’s a trio that’s comforting, homey, and classic in the best possible way.


While these oatmeal bars are fine on their own, my favorite way to eat them is warmed up for breakfast with extra sliced bananas and peanut butter.

The Ingredients

  • Old Fashioned Oats. Make these bars wholesome, filling, and slightly chewy (like these Granola Cookies). For best results, do not swap for quick or instant oats as this will impact the overall texture of the bars.
  • Whole Wheat Flour. I will always take any opportunity to sneak in some whole grain goodness into a recipe (see these Apple Oatmeal Cookies. If you don’t have whole wheat flour on hand, you may swap for an equal amount of all-purpose flour.
  • Cinnamon. Warm, earthy cinnamon pairs perfectly with the tender, nutty oats, and creamy dreamy peanut butter.
  • Banana. Adds moisture and naturally sweetens the bars (just like in Healthy Banana Bread). If you don’t love bananas, you may swap for other fresh or dried fruit. Blueberries are a wonderful substitution and raisins or dried cranberries are another great option.
  • Honey. Helps bind the ingredients together, adds sweetness, and helps the bars caramelize and turn golden in the oven.
  • Peanut Butter. Gives these oatmeal breakfast bars a subtle peanut butter flavor. Almond butter, sun butter, or cashew butter may also be used.
  • Applesauce. Another all-natural sweetener for these healthy oat bars that also adds moisture and helps bind everything together. (It does the same thing for these Applesauce Muffins.)
  • Milk. Helps bring everything together into a cohesive batter.
  • Baking Powder. Gives these bars a gentle rise and soft-baked texture.
  • Egg. Keeps these bars soft and tender.
  • Vanilla. Just a kiss of pure vanilla extract to marry everything together.

Frequently Asked Questions

Are Oatmeal Breakfast Bars Gluten Free?

No. This recipe, as it is written, is not gluten free. If you would like to make a gluten free oatmeal breakfast bar, readers have reported success swapping the whole wheat flour for an equal amount of oat flour or almond flour. Be advised that the texture of the bars may turn out slightly different however using one of these swaps.

What Can I Swap the Applesauce for?

To be honest, omitting the applesauce isn’t something I recommend. The applesauce both binds and moistens the bars so it’s an important ingredient! The closest thing I can suggest (and readers have reported success with) is pumpkin puree, though it will affect the flavor. Another idea is to try replacing it with half oil and half yogurt, though I haven’t tried it this way, so it would be an experiment.

Can I Make Oatmeal Breakfast Bars Vegan?

Possibly. I have not tried making these oat bars vegan so it would be an experiment. I would suggest swapping the honey for maple syrup and the milk for your favorite non-dairy milk of choice. As for the egg, you could try swapping it for a flax egg.

Homemade Granola Bars: Recipe Substitutions And Cooking Tips

The goal is to make this homemade granola bars recipe work for YOU and your family’s needs! As always, if you try out this recipe (with or without substitutions!) we’d love to hear how it goes!

  • Gluten-Free – Rolled oats are naturally gluten-free, however, they may come in contact with gluten-containing grains such as wheat, barley, or rye thus becoming contaminated with gluten. Make sure to use certified gluten-free oats if your gluten-free granola bars are intended for someone with celiac disease
  • Nut-Free – Swap out the peanut butter for sunflower seed butter, tahini, or pumpkin seed butter
  • Dairy-Free – Use dairy-free mini chocolate chips, such as Enjoy Life brand
  • Egg-Free and Vegan – Substitute 2 “flax eggs”. To make enough flax egg mixture for this recipe, mix 2 tablespoons ground flaxseed (or flaxseed meal) with 5 tablespoons water. Let set for 5-10 minutes before adding to the recipe
  • High-Protein Granola Bars – Feel free to add in your favorite protein powder! Simply substitute 1/2 cup of protein powder for 1/2 cup of oats. See our posts on our top recommended Whey Protein Powders and Plant-Based Protein Powders. You could also mix in unflavored collagen peptides for a protein addition that will give your hair, skin, and nails a health boost.
