# Expert Advice:

01 -
  • These bars taste like a cross between banana bread and peanut butter cookies but with none of the flour mess
  • The texture is impossibly moist and stays fresh for days, unlike typical gluten-free baking that dries out within hours
02 -
  • Overripe bananas with plenty of brown spots are non-negotiable here, green bananas will make the bars dense and lack sweetness
  • These continue to firm up as they cool, so don't panic if the center seems slightly jiggly when you first pull them from the oven
03 -
  • Use the parchment paper overhang to lift the entire batch out at once, then cut on a cutting board for perfectly clean edges
  • If using natural peanut butter, stir it thoroughly before measuring since the oil separates during storage
