Healthy Peanut Butter Banana Oatmeal Bars + Bites (Gluten-Free)

These healthy oat bars are perfect as a grab-in-go breakfast. They're packed with peanut butter, banana, oatmeal and, most importantly, dark chocolate chunks. Make sure to buy gluten-free oats if you care about that sort of thing.
Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes
Servings 16 bars


  • 1 cup mashed over-ripe mashed banana from about 2 ½ bananas
  • 1 cup almond milk I used vanilla
  • ¼ cup maple syrup
  • ¼ cup creamy peanut butter
  • 1 large egg
  • 2 cups gluten-free rolled oats
  • ½ cup gluten-free oat flour see note
  • 1 ¼ teaspoon gluten-free baking powder
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon sea salt
  • 1/4 cup roughly chopped dark chocolate or chips preferably 70 percent cacao


  1. Preheat the oven to 350 degrees. Grease an 8x8 inch baking pan or 2 mini muffin tins (I did one dozen mini muffins and made a half portion of bars in a loaf pan).
  2. In a large mixing bowl, combine the banana, almond milk, maple syrup, peanut butter and egg; whisk until smooth.
  3. In a second medium bowl, stir together the oats, oat flour, baking powder, cinnamon and salt until well combined.
  4. Fold the dry ingredients into the wet and mix until just incorporated. Stir in the chocolate. Transfer to the prepared pan(s). If using the muffin tins, add a scant tablespoon to each cup.
  5. Bake in the oven until lightly browned and a toothpick inserted in the center comes out clean, about 25 minutes. Allow to cool in the pan.
  6. I like these best served warm. Otherwise, store them in an airtight container in the fridge for up to a week of easy breakfasts and snacking.

Recipe Notes

You can make your own oat flour by pulsing rolled oats in a food processor until finely ground into meal.
