Equipment

  • Large mixing bowl
  • Fork
  • Potato masher
  • Spatula
  • 8x8 inch baking dish
  • Parchment paper
  • Cutting board

Ingredients
  

  • 2 ripe bananas mashed
  • 1/2 cup creamy peanut butter stir well if using natural
  • 1/4 cup honey or maple syrup adjust to taste
  • 1 tsp vanilla extract
  • 2 cups old-fashioned rolled oats
  • 1/4 cup ground flaxseed
  • 1/4 cup chopped nuts optional: walnuts or pecans
  • 1/4 cup mini chocolate chips or dried fruit optional
  • pinch of salt

Instructions
 

  • Step 1: Mash 'Em Up: Grab a large mixing bowl and your ripe bananas. Use a fork or a potato masher to mash them until they're nice and smooth. A few small lumps are totally fine and add character!
  • Step 2: Wet Ingredients Unite: To your mashed bananas, add the creamy peanut butter, honey (or maple syrup), and vanilla extract. Give it a good stir until everything is beautifully smooth and evenly combined. It should look like a glorious, sweet, nutty paste.
  • Step 3: Dry Meets Wet: Now, it’s time to bring in the stars of the show! Add your rolled oats, ground flaxseed, and that essential pinch of salt to the wet mixture. Stir thoroughly, making sure all those dry bits are well coated and distributed. You want every bite to be perfectly balanced.
  • Step 4: Fold in the Goodies: If you're using them, gently fold in your chopped nuts, chocolate chips, or dried fruit. This is where you can really personalize your bars! I love a mix of mini chocolate chips and a few pecans for that extra texture.
  • Step 5: Prepare Your Dish: Line an 8x8-inch baking dish with parchment paper. Make sure to leave a bit of an overhang on the sides – this is your secret weapon for easily lifting the whole slab out later.
  • Step 6: Press It Down: Transfer the delicious mixture into your prepared dish. Now, here's where you get to use a little elbow grease! Use a spatula, or even your clean hands, to press the mixture down firmly and evenly into the dish. The more compact it is, the better your bars will hold together.
  • Step 7: Chill Out: This is the most important step for structural integrity! Place the dish in the refrigerator for at least 2 hours, or until the bars are completely firm. Don't rush this part – patience will be rewarded with perfect bars.
  • Step 8: Slice and Serve: Once the mixture is set, use the parchment paper overhang to gently lift the entire block out of the dish. Place it on a cutting board and slice it into bars or squares of your desired size. Voila!

Notes

These versatile bars can be customized by swapping peanut butter for almond, cashew, or sunflower seed butter, or using agave nectar or brown rice syrup as sweeteners. Enhance texture with shredded coconut, pumpkin seeds, or sunflower seeds, or boost flavor with cinnamon, nutmeg, or orange zest. For chocolate lovers, dark or white chocolate chips, or a melted chocolate drizzle work wonderfully. Dried cranberries, cherries, or apricots can add fruity notes. For best results, use ripe bananas, press the mixture firmly into the pan, and do not skip the refrigeration time (at least 2 hours, or 30-45 minutes in the freezer if hurried). Parchment paper ensures easy removal. Store bars in an airtight container in the refrigerator for 5-7 days. They also freeze well for up to 3 months; thaw on the counter or microwave. While old-fashioned rolled oats are recommended for chewiness, quick oats can be used for a softer bar. These bars are naturally gluten-free if certified gluten-free oats are used. Protein powder can be added (1-2 scoops) with a potential need for a tiny splash more liquid. No food processor is required for this recipe.
