Banana Peanut Butter Oat Bars – Easy Healthy Squares and Bars Recipe Ideas

By: Aleda

🕒 Prep Time: 8 minutes
🔥 Bake Time: 22 minutes
⏱️ Total Time: 30 minutes
🍽️ Yields: 12 bars
📂 Type: Dessert / Snack

You’ll Need:

  • 2 ripe bananas, medium-sized
  • ½ cup natural creamy peanut butter
  • ½ cup maple syrup (the real stuff!)
  • 3 tablespoons melted coconut oil (or swap for avocado oil)
  • ½ teaspoon vanilla extract
  • 2 cups rolled oats (old-fashioned style)
  • 2 scoops collagen peptides (~20g) or your favorite protein powder
  • ½ cup chocolate chips (or cacao nibs/dried fruit for a vegan twist)
  • ¼ cup chopped walnuts (optional but delish)
  • ¼ teaspoon kosher salt

How to Make Them:

  1. Preheat your oven to 350°F (175°C) and line an 8x8-inch pan with parchment paper, leaving overhang for easy lifting.
  2. Mash those bananas in a large mixing bowl until smooth and pudding-like. Stir in the peanut butter, maple syrup, melted oil, and vanilla until well blended.
  3. Mix in the dry stuff: oats, protein powder, chocolate chips, walnuts (if using), and salt. Stir everything until the mixture is evenly combined and coated.
  4. Transfer to the pan and press into an even layer. Sprinkle a few extra chocolate chips on top if you’re feeling fancy.
  5. Bake for 28–32 minutes, or until the edges are lightly golden and the center feels set. Don’t overbake—they’ll firm up more as they cool.
  6. Let the bars rest in the pan for about 30 minutes. Then lift them out using the parchment and let them cool completely on a wire rack.
  7. Slice into 12 bars once cooled. Optional: sprinkle with a bit of flaky sea salt for that sweet-salty magic.
  8. 👉 Best stored in an airtight container. Keep refrigerated if not eaten within 2 days for max freshness!
