Oatmeal Breakfast Bars are one of the very first recipes I ever posted on my site.

In fact, this recipe is so simple, many of you bake them with your kiddos too!

Fill-You-Up Peanut Butter Banana Oatmeal Breakfast Bars

The origin of these baked oatmeal bars recipe is my friend Elisabeth, who created it in a desperate quest to find an oatmeal breakfast bar that would keep her first-year medical-resident husband full during the long hours he had to endure between breaks at the hospital.

She offered me one while Ben and I were visiting her in Nashville, and I was simultaneously hooked and FULL. Peanut Butter Oatmeal Breakfast Bars have been a regular in my recipe rotation ever since.

This Oatmeal Breakfast Bars recipe combines the three musketeers of peanut butter, banana, and oatmeal.

I also took the liberty of swapping out the agave Elisabeth uses for honey, because I love its flavor with the peanut butter and banana. It’s a trio that’s comforting, homey, and classic in the best possible way.

Ingredients needed to make Banana Honey Oatmeal Breakfast Bars
The texture of the Banana Honey Oatmeal Breakfast Bars is noticeably denser than banana bread, but they are not dry or crunchy like a granola bar either. They are somewhere in between, which it turns out is a very good place for an oatmeal bar to be.

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.

I also like having these bars on hand to get me through that last two hours before dinner, when it’s still too early to eat a full meal, but I’m hungry anyway.

Final selling points: Oatmeal Breakfast Bars are easy, fast, and flexible.

Elisabeth is a busy mom with two toddlers and the last person you will find fussing over a recipe. Simply stir together the dry and wet ingredients, pour them into a pan, and bake. You can swap the banana for different fresh or dried fruits or try a different nut butter instead of peanut butter. I used this same base recipe to make Strawberry Oatmeal Breakfast Bars.

Oatmeal Breakfast Bars can also be frozen for up to four months. Go big and bake them in bulk.

Oatmeal Breakfast Bars

Oatmeal Breakfast Bars are a healthy, filling, and absolutely delicious! With peanut butter, banana, honey, and oatmeal, these yummy bars will keep you powered for hours. These breakfast bars are easy to make, can be frozen for up to four months, and are great for snacks too.

Yield: 8 large bars

Prep Time: 10 minutes

Cook Time: 35 minutes

Total Time: 45 minutes

Ingredients:

  • 2 cups old fashioned oats
  • 1 cup whole wheat flour
  • 2 teaspoons cinnamon
  • 1 teaspoon baking powder
  • 1/4 teaspoon kosher salt
  • 1 1/2 cups milk (I used unsweetened vanilla almond, but any kind will do nicely)
  • 3 tablespoons honey*
  • 2 tablespoons peanut butter (creamy or crunchy—I used natural creamy)
  • 1/2 cup unsweetened applesauce
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1 medium banana, quartered and diced

Directions:

  1. Place rack in the center reheat oven to 375 degrees. Lightly coat an 8×8 inch square pan with cooking spray.
  2. In a medium bowl, stir together the oats, whole wheat flour, cinnamon, baking powder, and salt. In a separate large bowl, combine the milk, applesauce, egg, honey, peanut butter, and vanilla.
  3. Pour the dry ingredients into the wet mixture and stir to combine. The batter will be very wet. Fold in the diced banana, then pour into the prepared baking pan.
  4. Bake for 35 minutes or until thickened and golden and a toothpick inserted in the center comes out clean. Cool, cut into bars, and serve.

*As the recipe is written, these bars are very lightly sweet. If you prefer a sweeter bar, increase the honey to 4-5 tablespoons.

Storage: Once cooled, bars can be wrapped individually in plastic and kept in the refrigerator for 5 days or frozen in a zip-top bag for up to 4 months. Let thaw in the refrigerator for 24-48 hours before serving. For a larger yield, increase the ingredient quantities by 1.5 and bake in a 9×13 inch pan for 25-30 minutes.
