FAQs

Why did my banana and walnut loaf turn out dense?

This usually happens when the batter is overmixed or the bananas aren’t ripe enough. Mix gently once the flour is added and use very ripe bananas with brown spots for a lighter, softer crumb.

How do I stop the loaf from browning too quickly on top?

If the top is colouring too fast, loosely cover the loaf with foil halfway through baking. This protects the surface while allowing the centre to cook through evenly.

Can I freeze banana and walnut loaf?

Yes, it freezes very well. Let the loaf cool completely, then wrap it tightly or freeze individual slices. Defrost at room temperature before serving.

How do I know when the loaf is fully baked?

Insert a skewer into the centre of the loaf. It should come out clean or with a few dry crumbs. If there’s wet batter, return the loaf to the oven and check again after a few minutes.
