FAQs

Why is my lemon polenta cake crumbly after baking?

Lemon polenta cake can turn crumbly if coarse polenta is used or if the cake is overbaked. Always use fine polenta and remove the cake as soon as it’s just set. Pouring the lemon syrup over the cake while it’s still warm also helps bind the crumb and keep it moist.

When should I pour the lemon syrup over the polenta cake?

The syrup should be poured over the cake immediately after baking, while the cake is still warm. Pricking the surface with a skewer first allows the syrup to soak in evenly, giving the cake its signature moist texture.

Can I make lemon polenta cake ahead of time?

Yes, lemon polenta cake is ideal for making ahead. The flavour actually improves after a few hours as the syrup settles into the cake. Store it wrapped at room temperature for up to 3 days or refrigerate it for longer freshness.

Why did my lemon polenta cake sink slightly in the middle?

A slight dip can happen if the cake is underbaked or if the oven door is opened too early. Bake on the middle shelf and avoid checking before the 35-minute mark. Letting the cake cool gradually in the tin also helps it hold its shape.
