FAQs

  • Why brown the butter in this recipe?

Browning butter adds a rich, nutty flavor that enhances the overall taste of the cookie bars, creating a deeper, more complex profile compared to regular melted butter.

  • Can I use unripe bananas for this recipe?

No, use ripe or overripe bananas. They provide more natural sweetness and moisture, which helps create a softer, more flavorful cookie bar.

Overmixing develops too much gluten, resulting in tough, dense cookie bars instead of soft, tender ones. Gently fold ingredients just until combined.

  • Avoid overmixing the dough to prevent tough, dense bars; mix just until ingredients are combined to keep the texture tender and soft.
  • Create gluten-free version by substituting all-purpose flour with a 1:1 gluten-free baking blend, ensuring the same delicious texture and taste.
