– 1/2 tsp. vanilla extract
– 2 cups old-fashioned rolled oats

How to Make Banana Peanut Butter Oat Bars
Step 1: Preheat the Oven
Preheat your oven to 350ºF (175ºC). Line an 8×8 baking dish with parchment paper to prevent sticking.
Step 2: Mash the Bananas
In a mixing bowl, place the ripe bananas. Use a fork to thoroughly mash them until they are pureed.
Step 3: Combine Wet Ingredients
Stir in the following ingredients into the mashed bananas:
* 1/2 cup natural creamy peanut butter
* 1/2 cup pure maple syrup
* 3 Tbsp. coconut oil (or avocado oil)
* 1/2 tsp. vanilla extract
Mix until everything is well combined.

Step 6: Cool and Slice
Remove from the oven and let cool in the pan for about 30 minutes. Use the parchment paper to lift out the bars once cooled completely. Slice into 12 equal pieces. For an extra touch, consider sprinkling some flaky salt on top before serving. Store any leftovers in the refrigerator after two days.

- Measure ingredients accurately: Precision is key in baking. Use measuring cups and spoons to ensure correct ingredient ratios.
- Cool before slicing: Allow the bars to cool completely in the pan before slicing. This prevents them from crumbling.
- Experiment with add-ins: Feel free to customize by adding nuts, seeds, or dried fruits based on your preferences.

Common Mistakes to Avoid
To ensure your Banana Peanut Butter Oat Bars turn out perfectly, be mindful of these common mistakes.
- Using unripe bananas: Unripe bananas lack the sweetness and creaminess that ripe bananas provide. Always choose medium ripe bananas for the best flavor and texture.
- Skipping the rest time: Letting the bars cool in the pan is essential. Skipping this step can result in crumbly bars instead of a cohesive texture. Be patient!
- Not measuring ingredients accurately: A common pitfall is eyeballing measurements, especially for oats and peanut butter. Use precise measuring cups for consistent results.
- Overbaking the bars: Baking for too long can dry out your bars. Keep an eye on them and take them out when they are just set.
- Ignoring optional ingredients: Optional ingredients like walnuts or chocolate chips add flavor and texture. Don’t skip them if you want a richer taste!
