FAQs

Why did my coffee and walnut loaf sink in the middle?

A sunken loaf usually means the cake was underbaked or the oven door was opened too early. Bake until a skewer comes out clean and avoid opening the oven during the first two-thirds of baking time.

How strong should the coffee flavour be in coffee and walnut loaf?

The coffee flavour should be noticeable but not bitter. Dissolving the coffee granules in a small amount of hot water before adding them to the batter helps spread the flavour evenly.

Can I use fresh coffee instead of instant coffee?

Yes, strong brewed coffee can be used, but reduce the liquid slightly so the batter does not become too wet. Instant coffee gives more consistent flavour and is easier to control.

How do I keep coffee and walnut loaf moist?

Do not overbake the loaf and store it in an airtight container once cooled. Adding icing after the cake has fully cooled also helps lock in moisture.
