Recipe Tips

  • Use ripe bananas. The riper the bananas, the sweeter and softer they’ll be, making them easier to mash and naturally sweeten the bars.
  • For a smooth texture, use creamy peanut butter, but you can substitute with other nut butters like almond or cashew if desired.
  • Leave some parchment paper hanging over the edge of the pan for easy removal after baking.
  • Don’t overbake. The bars should be slightly golden but soft. 

Storing and Reheating

Storing: Keep the bars in an airtight container in the fridge for up to 1 week.

To reheat: Let them sit at room temperature for an hour before serving, or microwave straight from the fridge for about 10-15 seconds to soften.

Frequently Asked Questions

Can I freeze these bars?

Yes. Wrap bars individually in plastic wrap or place them in a freezer-safe bag. Freeze for up to 2 months. Thaw overnight in the fridge or at room temperature for an hour before serving.  

Can I use quick oats instead?

Quick oats will work, but they’ll give you a softer, denser bar with less chew. The bars may also be a bit more compact since quick oats absorb moisture faster and break down more during baking.

Rolled oats are better because they hold their shape, giving the bars that classic chewy texture most people expect.
