I love creating nutritious snacks that leave me feeling satisfied and also taste like a treat. My healthy banana snack cake and peanut butter granola definitely fit the bill!

These Banana Peanut Butter Oatmeal Bars also check all the boxes. I started making them years ago when I wanted my boys to have a healthy after school snack, and they quickly became a favorite.

They’re packed with wholesome rolled oats, banana, peanut butter and some dark chocolate chips for good measure, and there’s no refined sugar, dairy or gluten.

I love that they’re versatile enough to serve for snacks and breakfast, and they double as a sweet treat.

They’re also incredibly easy to whip up, which is probably why I make them so often.

If you’re not in the mood to bake, be sure to check out my no bake peanut butter bars! They’re just as satisfying and you don’t even need to turn on the oven. 🙂

Ingredient notes

  • Rolled oats. Be sure to opt for old fashioned rolled oats for the best texture. Quick oats may be used in a pinch, but steel cut oats will not work in this recipe.
  • Banana. Ripe bananas lend natural sweetness to the bars and also act as a binding agent. The more ripe the bananas, the sweeter your bars will be.
  • Peanut butter. Adds protein and healthy fats, and is an essential ingredient. For best results, use natural peanut butter with no added sugar. It may be substituted with your favorite nut butter or sun butter.
  • Oil. Use whatever type of oil that you have on hand.
  • Maple syrup. Substitute the maple syrup with honey if desired.
  • Egg. The egg acts as a binder in the oat bars.
  • Baking powder. Provides leavening in the bars.
  • Chocolate chips. Optional but highly recommended! Use your favorite variety.
