Ingredients
  

  • 2 ripe bananas mashed; the riper, the better!
  • 1/2 cup creamy peanut butter your favorite kind, natural without added sugars recommended
  • 1/4 cup honey or maple syrup natural sweetener and binder
  • 1 tsp vanilla extract
  • 2 cups old-fashioned rolled oats quick oats can be used in a pinch, but rolled oats give the best result
  • 1/4 cup ground flaxseed for healthy fats and fiber; helps with binding
  • 1/4 cup chopped nuts walnuts, pecans, almonds – pick your favorite
  • 1/4 cup mini chocolate chips or dried fruit dried cranberries, raisins, or chopped apricots are also delicious
  • salt a pinch; to balance sweetness

Equipment

  • Large Mixing Bowl
  • Fork
  • Spatula
  • 8x8-inch baking dish
  • Parchment Paper
  • Sharp Knife

Method
 

  1. Step 1: First things first, grab a large mixing bowl. You'll want to take those beautifully ripe bananas and mash them until they're nice and smooth. A fork works perfectly for this job!
  2. Step 2: Now, add your creamy peanut butter, the honey or maple syrup, and that lovely vanilla extract to the mashed bananas. Give it a good stir until everything is perfectly smooth and evenly combined. It should look like a rich, creamy base for our bars.
  3. Step 3: Next, it's time to bring in the dry gang! Toss in the old-fashioned rolled oats, the ground flaxseed, and that little pinch of salt. Stir everything thoroughly until all the dry ingredients are completely coated by the wet mixture. You want to make sure there are no pockets of dry oats hiding.
  4. Step 4: This is where you get to personalize them! Gently fold in your chopped nuts, and those delightful mini chocolate chips or dried fruit. I love adding mini chocolate chips because they distribute so well, but a mix of both is also fantastic!
  5. Step 5: Prepare your baking dish. Line an 8x8-inch baking dish with parchment paper, making sure to leave a bit of an overhang on the sides. This little trick will make it super easy to remove the bars once they're firm.
  6. Step 6: Transfer the entire mixture into your prepared dish. Now, this is important: use a spatula or even your clean hands to press the mixture down very firmly and evenly into the dish. The firmer you press, the better your bars will hold together. You want them compact!
  7. Step 7: The hardest part: patience! Place the dish in the refrigerator for at least 2 hours. This chilling time is crucial for the bars to set up properly and become firm enough to slice.
  8. Step 8: Once they're nice and firm, lift the parchment paper to remove the entire block of deliciousness from the dish. Place it on a cutting board and slice it into bars or squares. I usually go for about 9 or 12 squares, depending on how big I want them.

Notes

Store the bars in an airtight container in the refrigerator for up to 5-7 days. For longer storage, wrap individual bars tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. Just pull one out a few minutes before you want to enjoy it, or even enjoy it slightly frozen for a chewy, cool treat! Ensure bananas are very ripe (with brown spots) for optimal sweetness and moisture. Press the mixture down very firmly into the dish to ensure the bars hold together well. The refrigeration step is crucial for the bars to set up properly; give them the full 2 hours or even longer. Use a sharp knife for clean slices.
